电化学CO2还原(CO2RR)生成的CO是费托法生产高附加值化学原料的关键原料。有文献报道,通过在金属催化剂中引入轴向N配体,M-N4部分使得CO2RR的性能显著改善。这种配位可以破坏M-N4的对称电子结构,进而影响CO2RR中间体的结合能,这证实了轴向配位的关键作用。 故通过杂原子调节配位环境以破坏M-N4活性位点的对称电子结构,...
Their monotonous effects on the CO2RR were comprehensively elucidated. Engineering the particle size and Fe doping is critical to control extrinsic morphological factors of FeN 4 sites for optimal porosity, electrochemically active surface areas, and the graphitization of the carbon support. In contrast...
CO2RR performances The electrochemical CO2RR performances were then evaluated for these catalysts in a three-electrode setup using a two-compartment electrochemical cell with CO2-saturated 0.1 M NaHCO3 solution (pH = 6.8). The gas products were quantified by gas chromatography. As shown in the lin...

Recently, two-dimensional FeN4-embedded graphene has received increasing attention as a promising catalyst for CO2RR. Here, by means of density functional theory computations combined with the non-equilibrium Green's function (NEGF) method, we proposed a detection device to evaluate the performance ...
