Oxygen Evolution Reaction: Enhanced Oxygen Evolution Reaction Activity of Nanoporous SnO₂/Fe₂O₃/IrO₂ Thin Film Composite Electrodes with Ultralow Noble Metal Loading (Adv. Mater. Interfaces 3/2019)

Abstract

Iron oxide (rust) is an attractive contender as a water oxidation anode material due to its stability and abundance. The limitations associated with its low catalytic activity and electrical conductivity are overcome by combining it with tin oxide and iridium oxide in a nanoporous geometry.

Single Atom Catalysts for Photoelectrochemical Water Splitting

“…Aligned with this objective, noble metal-based SACs have been investigated for photoelectrochemical HER and OER. Specifically, Pt and Ir SACs were developed for boosting the PEC performance of Cu 2 O, [128,129] Fe 2 O 3 , [130,131] and Si [132,133] photoelectrodes by improving catalytic activity, facilitating photogenerated charge transfer with high photon-to-conversion efficiency. Recent studies have focused on surface modification and interface engineering of photoelectrodes employing noble metal SACs.…”
