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, showing high photocatalytic activity for hydrogen production (5.71 mmol h−1 g−1) in the water–lactic acid system under visible-light irradiation for the first time, exhibiting excellent stability and recyclability.
