Enhanced plasmon-driven photoelectrocatalytic methanol oxidation on Au decorated -Fe2O3 nanotube arrays

Highly ordered, porous -Fe2O3/Au nanotube arrays (NTAs) were successfully synthesized through a facile approach. Benefitting from the plasmonic effect, and unique aligned and porous structural features, the -Fe2O3/Au NTAs offer efficient and stable operation and exhibit a significantly enhanced catalytic activity for photoelectrochemical methanol oxidation with a faradaic efficiency of 79.23%.
