摘要

Abstract

Photocatalytic CO

reduction to valuable product exhibit promising prospect for solving the energy crisis and the greenhouse effect. Herein

Co-Ti

/g-C

(Co-TC/CN) composite with enhanced photocatalytic performance for converting CO

to CO and CH

was constructed by electrostatic self-assembly method. The close contact interface between Co-Ti

and g-C

nanosheets can be used as fast transport channels of photogenerated electrons and effectively promote the separation of photogenerated electrons and holes

and the interface between the Co and Ti

might be the active sites for CO

adsorption and activation. The optimized Co-Ti

/g-C

composite exhibited the highest photocatalytic performance with the CO and CH

production of 55.04 μmol·g

-1

and 2.29 μmol·g

-1

respectively

which were 7.5 times and 5.8

times than those of g-C

. Furthermore

the stability of g-C

was improved after coupling with Co-Ti
