Title
Improved H2 production of Pt-TiO2/g-C3N4-MnOx composites by an efficient handling of photogenerated charge pairs
Abstract

•By a simple impregnation method we achieve the g-C3N4-TiO2 photoactive composite.•The intimate junction of g-C3N4 with TiO2 leads to enhanced charge separation.•Composite photoactivity is strongly affected by Pt and MnOx co-catalysts.•Notably high photoactivities for phenol oxidation and H2 production are achieved.

Pt-TiO2/g-C3N4-MnOx hybrid structures are synthesized by means of a simple impregnation method of Pt-TiO2 and g-C3N4-MnOx. From the wide structural and surface characterization we have stated that TiO2/g-C3N4 composites are formed by an effective covering of g-C3N4 by TiO2. The modification of composite by Pt and/or MnOx leads to improved photoactivities for phenol degradation reaction. Moreover, enhanced photoactivities have been obtained for composites systems for H2 evolution reaction. The notably photocatalytic performance obtained was related with the efficient separation of charge pairs in this hybrid heterostructure.
