脉冲色谱H2-O2滴定法测定Pd/C催化剂中Pd的分散度 陈继东 张曼征 (湖北省化学研究所,武昌) 近来脉冲色谱H2-O2滴定法已用于 负载型Pd催化剂分散度的测定[1]。但对于 Pd/C催化剂,由于同时存在溶解氢和溢出 (Spillover)氢而使问题复杂化,至今未见 该法用于Pd/C中Pd的分散度测定的报道。
The actual catalyst is a NiFe or Fe metallocomplex encased in a protein. Tunnels in the protein allow H2 to access or egress from the active site. A series of FeS clusters form an electrical circuit connecting the active site with binding sites (for cytochromes, pyridine nucleotides, and ...
However, how the TMD crystal phase affects the growth of the secondary material is poorly understood, although relevant, particularly for catalyst development. In the case of Pt nanoparticles on two-dimensional MoS2 nanosheets used as electrocatalysts for the hydrogen evolution reaction7, only about ...
