Title: Formation and performances of porous InVO{sub 4} films

Abstract

Porous complex oxide films consisting of preferentially orientated orthorhombic phase of InVO{sub 4} have been prepared using a novel simple method by pyrolysis of amorphous complex precursor. The formation and controlling of porous InVO{sub 4} films can be easily obtained by modifying the calcination temperature. The pure orthorhombic InVO{sub 4} phase can be obtained at a relatively lower temperature (500 deg. C), and the films are preferential orientation of the (200) face parallel to the substrate. The phase separation mechanism was suggested for the formation of porous films. Under visible light irradiation ({lambda}>400 nm), porous InVO{sub 4} films have shown the photocatalytic activity for photodegradation of gaseous formaldehyde, and can generate photocurrent. The electrochemical properties of the films with different crystal structure and pore structure were also investigated.
