Guiding the Driving Factors on Plasma Super-Photothermal S-Scheme Core-Shell Nanoreactor to Enhance Photothermal Catalytic H(2) Evolution and Selective CO(2) Reduction.

Light-induced heat has a non-negligible role in photocatalytic reactions. However, it is still challenging to design highly efficient catalysts that can make use of light and thermal energy synergistically. Herein, the study proposes a plasma super-photothermal S-scheme heterojunction core-shell nanoreactor based on manipulation of the driving factors, which consists of α-Fe O encapsulated by g-C N modified with gold quantum dots. α-Fe O can promote carrier spatial separation while also acting as a thermal core to radiate heat to the shell, while Au quantum dots transfer energetic electrons and heat to g-C N via surface plasmon resonance. Consequently, the catalytic activity of Au/α-Fe O @g-C N is significantly improved by internal and external double hot spots, and it shows an H evolution rate of 5762.35 µmol h g , and the selectivity of CO conversion to CH is 91.2%. This work provides an effective strategy to design new plasma photothermal catalysts for the solar-to-fuel transition.
