Construction of SnO2/Co3O4 n-p heterojunctions by organometallic chemistry-assisted approach

SnO 2 /Co 3 O 4 n-p heterojunctions have been prepared by organometallic chemistry-assisted approach, where holy Co 3 O 4 nanosheets and (CH 3 ) 2 SnCl 2 were used as precursors. It is found that the surface oxygen-containing species could be regulated by changing the ratio of Co 3 O 4 precursors and Sn-containing organic compound. Our present work is of importance because it provides a new and effective approach for construction of heterojunctions .
