摘要： Low NO combustion of blended coals is widely used in coal-fired boilers in China to control NO emission; thus, it is necessary to understand the formation mechanism of NO and H S during the combustion of blended coals. This paper focused on the investigation of reductive gases in the formation of NO and H S in the reductive zone of blended coals during combustion. Experiments with Zhundong (ZD) and Commercial (GE) coal and their blends with different mixing ratios were conducted in a drop tube furnace at 1200°C–1400°C with an excessive air ratio of 0.6–1.2. The coal conversion and formation characteristics of CO, H S, and NO in the fuel-rich zone were carefully studied under different experimental conditions for different blend ratios. Blending ZD into GE was found to increase not only the coal conversion but also the concentrations of CO and H S as NO reduction accelerated. Both the CO and H S concentrations inblended coal combustion increase with an increase in the combustion temperature and a decrease in the excessive air ratio. Based on accumulated experimental data, one interesting finding was that NO and H S from blended coal combustion were almost directly dependent on the CO concentration, and the CO concentration of the blended coal combustion depended on the single char gasification conversion.Thus, CO, NO , and H S formation characteristics from blended coal combustion can be well predicted by single char gasification kinetics.

NiFeRuO<sub>xsub> nanosheets on Ni foam as an electrocatalyst for efficient

《化学科学与工程前沿（英文）》 2023年 第17卷 第11期   页码 1698-1706 doi: 10.1007/s11705-023-2334-8

摘要： The electrocatalyst NiFeRuOx/NF, comprised of NiFeRuOx nanosheets grown on Ni foam, was synthesized using a hydrothermal process followed by thermal annealing. NiFeRuOx/NF displays high electrocatalytic activity and stability for overall alkaline seawater splitting: 98 mV@ 10 mA∙cm−2 in hydrogen evolution reaction, 318 mV@ 50 mA∙cm−2 in oxygen evolution reaction, and a cell voltage of 1.53 V@ 10 mA∙cm−2, as well as 20 h of durability. A solar-driven system containing such a bifunctional NiFeRuOx/NF has an almost 100% Faradaic efficiency. The NiFeRuOx coating around Ni foam is an anti-corrosion layer and also a critical factor for enhancement of bifunctional performances.

Superior performance in visible-light-driven hydrogen evolution reaction of three-dimensionally ordered macroporous SrTiO decorated with ZnCdS

《化学科学与工程前沿（英文）》 2021年 第15卷 第6期   页码 1561-1571 doi: 10.1007/s11705-021-2089-z

摘要： 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.

摘要：

深部煤层是分布最广泛的适宜二氧化碳（CO<sub>2sub>）地质封存的地层之一，且通常位于大型CO<sub>2sub>排放源附近。将CO<sub>2sub>注入到煤层中具有巨大的CO<sub>2sub>封存潜力，同时可以提高煤层气的采收率（CO<sub>2sub>-ECBM）。本文采用原位同步辐射X射线显微CT扫描技术，首次在原位条件下直接证明了注入氮气（N<sub>2sub>）可以置换解吸CO<sub>2sub>并减小因CO<sub>2sub>吸附引起的煤基质膨胀研究结果表明，煤层中注入经过简单处理的烟道气（主要成分为N<sub>2sub>和CO<sub>2sub>），是技术上可行的CO<sub>2sub>-ECBM 替代方案。其次，N<sub>2sub>的存在可以使煤层保持较高的渗透率，实现长期CO<sub>2sub>注入封存和煤层气增产。

Chemical poison and regeneration of SCR catalysts for NO<sub>xsub>

《环境科学与工程前沿（英文）》 2016年 第10卷 第3期   页码 413-427 doi: 10.1007/s11783-016-0832-3

摘要： Selective catalytic reduction (SCR) of NO with NH is an effective technique to remove NO from stationary sources, such as coal-fired power plant and industrial boilers. Some of elements in the fly ash deactivate the catalyst due to strong chemisorptions on the active sites. The poisons may act by simply blocking active sites or alter the adsorption behaviors of reactants and products by an electronic interaction. This review is mainly focused on the chemical poisoning on V O -based catalysts, environmental-benign catalysts and low temperature catalysts. Several common poisons including alkali/alkaline earth metals, SO and heavy metals etc. are referred and their poisoning mechanisms on catalysts are discussed. The regeneration methods of poisoned catalysts and the development of poison-resistance catalysts are also compared and analyzed. Finally, future research directions in developing poisoning resistance catalysts and facile efficient regeneration methods for SCR catalysts are proposed.

Effects of Pd doping on N

《环境科学与工程前沿（英文）》 2017年 第11卷 第6期 doi: 10.1007/s11783-017-0976-9

摘要： N O is a powerful greenhouse gas and plays an important role in destructing the ozone layer. This present work investigated the effects of Pd doping on N O formation over Pt/BaO/Al O catalyst. Three types of catalysts, Pt/BaO/Al O , Pt/Pd mechanical mixing catalyst (Pt/BaO/Al O +Pd/Al O ) and Pt-Pd co-impregnation catalyst (Pt-Pd/BaO/Al O ) were prepared by incipient wetness impregnation method. These catalysts were first evaluated in NSR activity tests using H /CO as reductants and then carefully characterized by BET, CO chemisorption, CO-DRIFTs and H -TPR techniques. In addition, temperature programmed reactions of NO with H /CO were conducted to obtain further information about N O formation mechanism. Compared with Pt/BaO/Al O , (Pt/BaO/Al O +Pd/Al O ) produced less N O and more NH during NO storage and reduction process, while an opposite trend was found over (Pt-Pd/BaO/Al O +Al O ). Temperature programmed reactions of NO with H /CO results showed that Pd/Al O component in (Pt/BaO/Al O +Pd/Al O ) played an important role in NO reduction to NH , and the formed NH could reduce NO to N leading to a decrease in N O formation. Most of N O formed over (Pt-Pd/BaO/Al O +Al O ) was originated from Pd/BaO/Al O component. H -TPR results indicated Pd-Ba interaction resulted in more difficult-to-reduce PdO species over Pd/BaO/Al O , which inhibits the NO dissociation and thus drives the selectivity to N O in NO reduction.

The effect of preparation conditions of Pt/Al

《环境科学与工程前沿（英文）》 2013年 第7卷 第3期   页码 457-463 doi: 10.1007/s11783-013-0512-5

摘要： Selective catalytic reduction of NO by H in the presence of oxygen has been investigated over Pt/Al O catalysts pre-treated under different conditions. Catalyst preparation conditions exert significant influence on the catalytic performance, and the catalyst pre-treated by H or H then followed by O is much more active than that pre-treated by air. The higher surface area and the presence of metallic Pt over Pt/Al O pre-treated by H or pretreated by H then followed by O can contribute to the formation of NO , which then promotes the reaction to proceed at low temperatures.
