The covalent assembly between a cobalt diimine-dioxime complex and a fullerenic moiety results in enhanced catalytic properties in terms of overpotential requirement for H evolution. The interaction between the fullerene moiety and PCBM heterojunction further allows for the easy integration of the cobalt diimine-dioxime - fullerene catalyst with a poly-3-hexylthiophene (P3HT):[6,6]-phenyl-C-butyric acid methyl ester (PCBM) bulk heterojunction, yielding hybrid photoelectrodes for H evolution from near-neutral aqueous solutions.
钴二亚胺 - 二肟配合物与富勒烯部分之间的共价组装在析氢过电位要求方面产生了增强的催化性能。富勒烯部分与PCBM异质结之间的相互作用进一步使得钴二亚胺 - 二肟 - 富勒烯催化剂能够轻松地与聚3 - 己基噻吩(P3HT):[6,6] - 苯基 - C - 丁酸甲酯(PCBM)本体异质结集成,从而产生用于从近中性水溶液中析氢的混合光电极。
