Thiolate-mediated photoreduction and aerobic oxidation cycles in a bismuth–bismuth oxide nanosystem towards thiol-to-disulfide photocatalytic transformation

Abstract

Bismuth(III) alkanethiolates [Bi(SR)3] formed by reacting Bi2O3 with alkanethiols (RSH) undergo a UV-blue driven ligand-to-metal charge transfer photoreduction to disulfides and Bi colloids, which are then oxidised to Bi2O3 by...
