Abstract Heterojunction engineering into quantum dot (QD) assemblies has emerged as an effective approach to optimize photocatalytic systems through enhanced charge separation and extended light‐harvesting capabilities. Nevertheless, fabricating QD heterojunctions with robust interfacial coupling remains challenging due stringent morphological lattice matching constraints. Here, a class of atomically fused ZnCdSe–CdS aerogels tailored heterointerfaces is reported for superior solar‐driven CO 2 reduction. The high compatibility between ZnCdSe CdS enables seamless heterojunction formation strong electronic coupling, while strategic Cd doping in ZnSe extends optical absorption maximize solar utilization. optimized exhibit exceptional photoreduction activity, achieving CH 4 production rate 240 µmol g⁻ 1 h⁻ 87% selectivity apparent yield (AQY) 1.2% under visible light. Combined spectroscopic characterization density functional theory (DFT) simulations elucidate that suppressed carrier recombination at the engineered interface serves key mechanistic determinant performance. This work establishes universal platform designing interfacial‐engineered aerogels, advancing their applicability high‐efficiency fuel generation systems.
