Facile preparation of yttrium and aluminum co-doped ZnO via a sol–gel route for photocatalytic hydrogen production

Abstract

Yttrium and aluminum co-doped ZnO were successfully synthesized by the sol–gel method. The obtained products showed high photocatalytic activity for hydrogen production (5.71 mmol h⁻¹ g⁻¹), and exhibited excellent stability and recyclability.
