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.

Abstract Ionothermal synthesis method often results in significant structural defects the prepared crystalline carbon nitride due to insufficient penetration of molten salt. Herein, a strategy involving addition foaming agent (NH₄Cl) precursor is adopted, which significantly enhances salt during ionothermal nitride. This more uniform internal unit and fewer detrimental (terminal amine groups hydrogen bonds formed by these groups) transformation from triazine‐heptazine mixed phase heptazine phase. improvement enables photocatalyst, upon loading cocatalysts, maximally utilize photogenerated electrons holes, establishing smooth pathway for surface protonation electron‐proton coupling. The show that photocatalytic production rate reaches 8.67 mmol g −1 h exhibits high apparent quantum efficiency 22.1% (λ = 400 nm) evolution. study elucidates relationship between crystal structure process. It also reveals impact factors on perspectives carrier behavior reaction kinetics.

Cu-based multinary selenide nanomaterials have garnered significant attention in photocatalytic and photovoltaic applications, owing to their unique electronic optical properties. However, the high-yield scalable synthesis of wurtzite colloidal nanocrystals via a versatile simple method has not yet been achieved. In this work, we report general hot-injection for diverse library quaternary nanocrystals, including Cu2CdSnSe4, Cu2ZnSnSe4, Cu2FeSnSe4, Cu2CoSnSe4, Cu2MnSnSe4, Cu3InSnSe5, Cu3GaSnSe5, CuZnInSe3, CuZnGaSe3, CuCdInSe3, Cu(InGa)Se2. As proof concept, Cu2CdSnSe4 are used as photocatalysts solar-to-hydrogen production, displaying good hydrogen evolution performance. Moreover, approach broad applicability other nanomaterials, which show potential wide range applications.
