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.
