Catalysis of gold nanoparticles supported on a layered double hydroxide

摘要

Water electrolysis is one of the most attractive approaches to produce green hydrogen. Its overpotential is originated from oxygen evolution reaction (OER). Therefore, active catalysts for OER have been intensively investigated. Among them, NiFe binary layered double hydroxide (NiFe-LDH) shows especially promising catalytic activity. This precious-metal-free catalyst has attracted much attention.
