Inexpensive synthesis of a high-performance Fe

Imran, Muhammad S. Haider, Hee Taik Kim

Frontiers of Chemical Science and Engineering 2016, Volume 10, Issue 3, Pages 405-416 doi: 10.1007/s11705-016-1579-x

Abstract: A sol-gel technique has been developed for the synthesis of a magnetite-silica-titania (Fe O -SiO -TiO ) tertiary nanocomposite with improved photocatalytic properties based on the use of inexpensive titania and silica precursors. The exceptional photocatalytic activity of the resulting materials was demonstrated by using them to photocatalyze the degradation of methylene blue solution. The best formulation achieved 98% methylene blue degradation. An interesting feature of the present work was the ability to magnetically separate and reuse the catalyst. The efficiency of the catalyst remained high during two reuses. The synthesized nanomaterials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, ultra-violet-visible spectroscopy, diffuse reflectance spectroscopy, and thermogravimetric analysis. XRD analysis revealed the formation of multicrystalline systems of cubic magnetite and anatase titania crystals. SEM and TEM characterization revealed well-developed and homogeneously dispersed particles of size less than 15 nm. FTIR spectra confirmed the chemical interaction of titania and silica. It was further noticed that the optical properties of the prepared materials were dependent on the relative contents of their constituent metal oxides.

CO2sub> capture using membrane contactors: a systematic literature review

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 4, Pages 720-754 doi: 10.1007/s11705-020-1992-z

Abstract: With fossil fuel being the major source of energy, CO emission levels need to be reduced to a minimal amount namely from anthropogenic sources. Energy consumption is expected to rise by 48% in the next 30 years, and global warming is becoming an alarming issue which needs to be addressed on a thorough technical basis. Nonetheless, exploring CO capture using membrane contactor technology has shown great potential to be applied and utilised by industry to deal with post- and pre-combustion of CO . A systematic review of the literature has been conducted to analyse and assess CO removal using membrane contactors for capturing techniques in industrial processes. The review began with a total of 2650 papers, which were obtained from three major databases, and then were excluded down to a final number of 525 papers following a defined set of criteria. The results showed that the use of hollow fibre membranes have demonstrated popularity, as well as the use of amine solvents for CO removal. This current systematic review in CO removal and capture is an important milestone in the synthesis of up to date research with the potential to serve as a benchmark databank for further research in similar areas of work. This study provides the first systematic enquiry in the evidence to research further sustainable methods to capture and separate CO .

Uncovering CO2sub> emission drivers under regional industrial transfer in China’s Yangtze River

Huijuan JIANG, Yong GENG, Xu TIAN, Xi ZHANG, Wei CHEN, Ziyan GAO

Frontiers in Energy 2021, Volume 15, Issue 2, Pages 292-307 doi: 10.1007/s11708-020-0706-z

Abstract: With the relocation of heavy industries moving from downstream region to upstream and midstream regions in the Yangtze River Economic Belt (YREB), it is critical to encourage coordinated low carbon development in different regions within the YREB. This paper uncovers the evolution of CO emissions in different regions within the YREB for the period of 2000–2017. It decomposes regional CO emission changes using the temporal and cross-regional three-layer logarithmic mean Divisia index (LMDI) method. Besides, it decomposes industrial CO emission changes using the temporal two-layer LMDI method. The research results show that economic growth is the major driver for regional CO emission disparities. The mitigation drivers, such as energy intensity and energy structure, lead to a more decreased CO emission in the downstream region than in the upstream and midstream regions. In addition, it proposes several policy recommendations based upon the local realities, including improving energy efficiency, optimizing energy structure, promoting advanced technologies and equipment transfers, and coordinating the development in the upstream, midstream and downstream regions within the YREB.
