Abstract The utilization of photogenerated carriers in interfacial oxidation and reduction reactions is limited due to the kinetic imbalance between ends. Rapid equilibration photoexcited metal nanostructures forming hot on ultrafast time scales has potential accelerating rate kinetics photocatalytic reactions. In this study, hollow nanocage structures with enhanced photothermal effect are designed achieve efficient catalytic evolution furfural hydrogen by enhancing relaxation scale carriers. formed spatial structure internal external separation facilitates absorption reactants sites. Meanwhile instrumental phonon‐photon synergy, which supplies driving force for coupling reaction through interactions. simultaneously prolongs thermal electron injection heat scattering reaction, balancing half‐reactions. This work significant finely optimize total energy utilization.

Photocatalytic CO2 reduction provides a sustainable route to combat climate change by converting into valuable chemicals using sunlight. This study presents both experimental and theoretical insights the of HCOOH biomass-derived carbon dots embedded onto phytochemical-based CdS quantum dots. The 0D CDs/CdS QDs(bio) composites exhibit rich sulfur vacancies more negative conduction band, effectively inhibiting photocorrosion (SO42-) while enhancing adsorption photocurrent response. Additionally, it reduced PL intensity increased decay time, suggesting enhancement charge separation suppression recombination. optimal 0.4CDs/CdS composite exhibited remarkable formation yield 439.51 μmol g-1 h-1 (apparent 3.81%) retaining its structural morphological stability. Density functional theory calculations reveal HCOO* as key intermediate, confirming thermodynamic preference for over CO with free energy -0.71 eV. introduces novel bio-based QDs modified CDs, providing mechanistic photocatalytic fuel production.
