Abstract

The present work introduces the formation of a highly organized one dimensional Ga₂O₃ nanoporous architecture by anodization of Ga metal at - 10 C in a mixture of phosphoric acid and ethylene glycol. In addition to pure Ga₂O₃, we perform in situ Zn doping by alloying Ga with 1 at.% Zn. After zinc doping, the Ga₂O₃ nanoporous layers demonstrate promising properties for photo-induced hydrogen generation from water.
