Preparation of thickness-tunable BiOCl nanosheets with high photocatalytic activity for photoreduction of CO2

Abstract: BiOCl nanosheets with different percentages of exposed {001} facets were prepared via mild hydrolysis by a controlled facile hot injection technique, which exhibited relatively high activity for photocatalytic reduction of CO2 to CH4.

[84] The photocatalytic benzyl alcohol oxidation is greatly determined by the position of VB of semiconductors, and BiOCl and Bi 12 O 17 Cl 2 was demonstrated to be efficient photocatalysts for oxidation of benzyl alcohol.…”
