Design and mechanism insight on SiC quantum dots sensitized inverse opal TiO with superior photocatalytic

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 12,   Pages 1913-1924 doi: 10.1007/s11705-023-2350-8

Abstract: The combination of SiC quantum dots sensitized inverse opal TiO2 photocatalyst is designed in this work and then applied in wastewater purification under simulated sunlight. From various spectroscopic techniques, it is found that electrons transfer directionally from SiC quantum dots to inverse opal TiO2, and the energy difference between their conduction/valence bands can reduce the recombination rate of photogenerated carriers and provide a pathway with low interfacial resistance for charge transfer inside the composite. As a result, a typical type-II mechanism is proved to dominate the photoinduced charge transfer process. Meanwhile, the composite achieves excellent photocatalytic performances (the highest apparent kinetic constant of 0.037 min–1), which is 6.2 times (0.006 min–1) and 2.1 times (0.018 min–1) of the bare inverse opal TiO2 and commercial P25 photocatalysts. Therefore, the stability and non-toxicity of SiC quantum dots sensitized inverse opal TiO2 composite enables it with great potential in practical photocatalytic applications.

Construction of defect-containing UiO-66/MoSe heterojunctions with superior photocatalytic performance

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 4,   Pages 449-459 doi: 10.1007/s11705-022-2226-3

Abstract: Metal–organic frameworks are recognized as promising multifunctional materials, especially metal–organic framework-based photocatalysts, which are considered to be ideal photocatalytic materials. Herein, a new type of UiO-66/MoSe2 composite was prepared using the solvothermal method. The optimum composite was selected by adjusting the mass ratio of UiO-66 and MoSe2. X-ray diffraction analysis showed that the mass ratio influenced the crystal plane exposure rate of the composite, which may have affected its photocatalytic performance. The composite is composed of ultra-thin flower-like MoSe2 that wrapped around cubic UiO-66, a structure that increases the abundance of active sites for reactions and is more conducive to the separation of carriers. The photocatalytic properties of the composite were evaluated by measuring the degradation rate of Rhodamine B and the catalyst’s ability to reduce Cr(VI)-containing wastewater under visible light irradiation. Rhodamine B was decolorized completely in 120 min, and most of the Cr(VI) was reduced within 150 min. The photochemical mechanism of the complex was studied in detail. The existence of Mo6+ and oxygen vacancies, in addition to the Z-type heterojunction promote the separation of electrons and holes, which enhances the photocatalytic effect.

Superior performance in visible-light-driven hydrogen evolution reaction of three-dimensionally ordered

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 6,   Pages 1561-1571 doi: 10.1007/s11705-021-2089-z

Abstract: It is of broad interest to develop emerging photocatalysts with excellent light-harvesting capacity and high charge carrier separation efficiency for visible light photocatalytic hydrogen evolution reaction. However, achieving satisfying hydrogen evolution efficiency under noble metal-free conditions remains challenging. In this study, we demonstrate the fabrication of three-dimensionally ordered macroporous SrTiO3 decorated with ZnxCd1−xS nanoparticles for hydrogen production under visible light irradiation (λ>420 nm). Synergetic enhancement of photocatalytic activity is achieved by the slow photon effect and improved separation efficiency of photogenerated charge carriers. The obtained composites could afford very high hydrogen production efficiencies up to 19.67 mmol·g−1·h−1, with an apparent quantum efficiency of 35.9% at 420 nm, which is 4.2 and 23.9 times higher than those of pure Zn0.5Cd0.5S (4.67 mmol·g−1·h−1) and CdS (0.82 mmol·g−1·h−1), respectively. In particular, under Pt-free conditions, an attractive hydrogen production rate (3.23 mmol·g−1·h−1) was achieved, providing a low-cost and high-efficiency strategy to produce hydrogen from water splitting. Moreover, the composites showed excellent stability, and no obvious loss in activity was observed after five cycling tests.

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 3,   Pages 467-472 doi: 10.1007/s11705-018-1717-8

Abstract:

It is highly attractive but still remains a great challenge to develop an efficient electrocatalyst for oxygen evolution reaction under nearly neutral conditions. In this work, we report the transformation of Ni3S2 nanowire array on nickel foam into the amorphous nickel carbonate nanowire array on nickel foam (NiCO3/NF). The resulting NiCO3/NF shows high electrocatalytic activity towards water oxidation and affords current density of 50 mA·cm−2 at overpotential of 395 mV in 1.0 mol·L−1 KHCO3. Moreover, this NiCO3/NF is also durable with a long-term electrochemical durability of 60 h. This catalyst electrode achieves a high turnover frequency of 0.21 mol O2·s−1 at the overpotential of 500 mV.

Superior Mechanical Behavior and Flame Retardancy FRP via a Distribution Controllable 1D/2D Hybrid Nanoclay Article

Zixuan Chen, Tianyu Yu, Zetian Yang, Zhibiao Wei, Yan Li, Weidong Yang, Tao Yu

Engineering 2024, Volume 40, Issue 9,   Pages 166-178 doi: 10.1016/j.eng.2024.03.017

Abstract:

The incorporation of commercial flame retardants into fiber-reinforced polymer (FRP) composites has been proposed as a potential solution to improve the latter's poor flame resistance. However, this approach often poses a challenge, as it can adversely affect the mechanical properties of the FRP. Thus, balancing the need for improved flame resistance with the preservation of mechanical integrity remains a complex issue in FRP research. Addressing this critical concern, this study introduces a novel additive system featuring a combination of one-dimensional (1D) hollow tubular structured halloysite nanotubes (HNTs) and two-dimensional (2D) polygonal flake-shaped nano kaolinite (NKN). By employing a 1D/2D hybrid kaolinite nanoclay system, this research aims to simultaneously improve the flame retardancy and mechanical properties. This innovative approach offers several advantages. During combustion and pyrolysis processes, the 1D/2D hybrid kaolinite nanoclay system proves effective in reducing heat release and volatile leaching. Furthermore, the system facilitates the formation of reinforcing skeletons through a crosslinking mechanism during pyrolysis, resulting in the development of a compact char layer. This char layer acts as a protective barrier, enhancing the material's resistance to heat and flames. In terms of mechanical properties, the multilayered polygonal flake-shaped 2D NKN plays a crucial role by impeding the formation of cracks that typically arise from vulnerable areas, such as adhesive phase particles. Simultaneously, the 1D HNT bridges these cracks within the matrix, ensuring the structural integrity of the composite material. In an optimal scenario, the homogeneously distributed 1D/2D hybrid kaolinite nanoclays exhibit remarkable results, with a 51.0% improvement in mode II fracture toughness (GIIC), indicating increased resistance to crack propagation. In addition, there is a 34.5% reduction in total heat release, signifying improved flame retardancy. This study represents a significant step forward in the field of composite materials. The innovative use of hybrid low-dimensional nanomaterials offers a promising avenue for the development of multifunctional composites. By carefully designing and incorporating these nanoclays, researchers can potentially create a new generation of FRP composites that excel in both flame resistance and mechanical strength.

Tailoring Photonic-Engineered Textiles with Butterfly-Mimetic Tertiary Micro/Nano Architectures for Superior Article

Hongyu Guo, Tianye Niu, Jianyong Yu, Xueli Wang, Yang Si

Engineering 2023, Volume 31, Issue 12,   Pages 120-126 doi: 10.1016/j.eng.2023.07.019

Abstract:

People could potentially mitigate heat discomfort when outdoors by combining passive radiative cooling (PRC) strategies with personal thermal management techniques. However, most current PRC materials lack wearing comfort and durability. In this study, a microarray technique is applied to fabricate the tailoring photonic-engineered textiles with intriguing PRC capability and appealing wearability. The developed radiative cooling textiles (RCTs) demonstrate appropriate air–moisture permeability, structural stability, and extended spectroscopic response with high sunlight reflectivity (91.7%) and robust heat emissivity (95.8%) through the atmospheric transparent spectral window. In a hot outdoor cooling test, a skin simulator covered by the RCTs displays a temperature drop of ∼4.4 °C at noon compared with cotton textiles. The evolution of our mimetic structures may provide new insights into the generation of wearable, thermal–wet comfortable, and robust textiles for exploring PRC techniques in personal thermal management applications.
