Electrospinning Preparation of GaN:ZnO Solid Solution Nanorods with Visible-Light-Driven Photocatalytic Activity toward H<sub>2</sub> Production

The development of a facile method for the synthesis of GaN:ZnO solid solution, an attractive material with a wurtzite-type structure, is vital to enhance its photocatalytic activity toward H<sub>2</sub> evolution. Herein, GaN:ZnO solid solution nanorods with diameters of around 180 nm w...
