摘要

本文研究了三维金-镍-钼(Au(NiMo))催化剂作为析氧反应(OER)的催化剂。采用电镀和电驱技术将催化剂沉积在钛表面。在1.2 ~ 5.2 μgAucm-2范围内，用少量Au晶修饰的NiMo在碱性介质中对OER的活性较未修饰的二元NiMo催化剂有所提高。当温度从25℃升高到75℃时，制备的三维二元NiMo/ Ti和Au(NiMo)/Ti催化剂的OER电流密度分别增加了约1.2 ~ 7.3倍和1.3 ~ 5.1倍。

Three-dimensional Au(NiMo)/Ti catalysts for efficient oxygen evolution reaction

In this study, three-dimensional gold-nickel-molybdenum (Au(NiMo)) catalysts have been studied as catalysts for the oxygen evolution reaction (OER). The catalysts have been deposited on a titanium surface using electroplating and galvanic displacement techniques. The modification of NiMo with a low amount of Au crystallites in a range of 1.2– 5.2 μgAucm–2 results in enhanced activity for OER in the alkaline medium compared to respective binary un-modified NiMo catalysts. The current densities for OER increase ca.1.2–7.3 and 1.3–5.1 times with an increase in temperature from 25 up to 75°C using the prepared 3D binary NiMo/ Ti and Au(NiMo)/Ti catalysts, respectively.
