Reactive Sputtering of Plasmonic Pt/ZnO Films for Decomposition of Gas‐Phase Methanol under Visible Light

Abstract

The preparation of ZnO films by a versatile and effective facing‐target sputtering method under various sputtering pressures is described. The ZnO films are coated with an ultrathin (2 nm) Pt layer through dc diode sputtering to form hybrid Pt/ZnO photocatalytic films. Interestingly, the Pt/ZnO films show an efficient visible‐light photoresponse for the decomposition of gas‐phase methanol owing to the unique surface plasmon resonance of the Pt film.
