Abstract
•Anodization of Ga, and Zn doped Ga in H3PO4 and ethylene glycol mixed electrolyte at − 10 °C•Formation of highly ordered self-organized nanoporous structures•After annealing and Pt decoration, generate H2 from H2O upon UV illumination
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.
