另外,研究发现,该催化剂展现出极强的抗一氧化碳毒化性能,经过一氧化碳毒化测试之后,该催化剂仍能保持95.38%的活性,而商业铂催化剂仅为13.76%。相关研究成果发表在Nano Letters上,论文题为“Neighboring Pt Atom Sites in an Ultrathin FePt Nanosheet for the Efficient and Highly CO-Tolerant Oxygen Reduction R...
近日,北京科技大学唐晓龙教授团队于化工领域顶级期刊Chemical engineering journal(中科院一区,IF=16.744)上发表题为“Recent advances in NO reduction with CO over copper-based catalysts: reaction mechanisms, optimization strategies, and anti-inactivation measures”的综述文章。该论文系统总结了Cu基催化剂催化CO+NO...
equation,2NO2+4CO = N2+4CO2. Enter the amount of any of the substances to determine the ideal amounts to maximize the theoretical yield of the reaction. To find the limiting and excess reagents when a non-ideal amount of each substance is used, you can use thelimiting reactant ...
Fig. 9. Schematic of a plausible reaction mechanism and intermediates for the synthesis ofn-butanol from CO2 hydrogenation over the Na–CuCo-9 catalyst. 总结 总结来说,我们展示了通过CO₂加氢,在双金属Co–Cu串联催化剂上实现了富含正丁醇的C₃+醇的直接和选择性生产,且偏离了ASF分布。严格的实验调节...
As O2 enters the vial of blood, the plasma pO2 increases and more O2 binds with hemoglobin.pO2Hb + O2 <———–>HbO2The reaction also causes the color of the red blood cells (RBCs) in the vial to change from purple to red.
