The composing effect of bismuth on titania hollow microspheres for their visible-light photocatalytic activity

Abstract

Bismuth-composed titania hollow microspheres are fabricated by an impregnating-calcination method using the hydrothermally prepared titania hollow microspheres as precursors and Bi(NO3)3 as Bi resource. A series of characterizations and analyses,...

Preparation and photocatalytic hydrogen evolution performance of square platform Cu2MoS4/lamellar ZnIn2S4

“…ZnIn 2 S 4 is widely used in photocatalysis due to its suitable forbidden band width, but it exhibits poor photocatalytic hydrogen evolution performance due to the high recombination rate of photogenerated electrons and holes. [20][21][22] In order to improve the photocatalytic performance, the construction of heterojunctions or adjustment of sulfur vacancies of ZnIn 2 S 4 to reduce the recombination efficiency of photogenerated carriers is usually used to improve the photocatalytic efficiency. For example, a composite of 5% CuInS 4 and ZnIn 2 S 4 exhibited enhanced hydrogen evolution efficiency by a factor of 5 over pure ZnIn 2 S 4 .…”
