CO 2 reduction (CO RR) with selective benzyl alcohol (BA) oxidation in a single photoredox reaction can simultaneously utilize photogenerated electrons and holes to realize efficient production of fuels value‐added chemicals. Herein, unique 2D/1D ZnIn S 4 /In O 3 (ZIS/In ) heterostructure is developed displaying outstanding performance for catalysis. As unequivocally illustrated by various advanced ex situ/in situ characterizations theoretic calculations, the notable catalytic performances originate from built‐in interfacial electric field within ZIS/In heterostructure, which strongly ameliorates separation transport charge carriers. Remarkably, activity further be boosted after coupling additional thermal treatments, product selectivity highly temperature dependent. Thereby, precise formation targeted products, serve as valuable industrial products controlled changing temperatures, including obtaining syngas different H /CO ratios reduction, well benzaldehyde, hydrogenated benzoin, dibenzyl ether (never reported BA during photocatalysis) conversion. This study offers constructive inspiring contribution reasonably developing catalysts, fully holes, demonstrate how controllably yield thermo‐
