Abstract

article i nfo Article history: Lamellar BiVO4 was prepared through a surfactant-assisted hydrothermal process. The obtained lamellar BiVO4 withmonoclinicphasewasusedasphotocatalystforthereductionofCO2,andexhibitedaselectivemethanolpro- duction undervisible-light irradiation.It isfoundthatthe methanol yield can be significantlyenhancedby adding NaOH solution intheBiVO4suspension because the causticsolution can dissolve moreCO2and the OH − servesas a stronger hole-scavenger as compared to water. The possible mechanism for the selective methanol production from the present photocatalytic CO2 reduction system was also discussed. © 2012 Published by Elsevier B.V.
