However, the selectivity of HB is still low due to the inevitable formation of benzaldehyde. Herein, we report In(OH)₃-ZnS photocatalyst for C<img>C coupling of BA into HB with very high selectivity (∼100 %). The introduction of In(OH)₃ onto ZnS with stable interaction facilitates light harvesting and separation of photo-excited charges. As a result, BA conversion on optimized In(0.1)-ZnS catalyst (73 %) is much higher than ZnS (29 %). Besides, the surface hydroxyl groups derived from In(OH)₃ enables the facile desorption of <img>CH(OH)Ph radical. Therefore, the over oxidation of <img>CH(OH)Ph radical into by-product of benzaldehyde can be effectively inhibited. More significantly, in-situ FTIR spectra and reduction of by-product manifest the instant reverse reduction process of benzaldehyde into <img>CH(OH)Ph radical during C<img>C coupling of BA, which is the key to realizing satisfied HB selectivity (100 %). Theoretical simulations reveal that the weak adsorption of <img>CH(OH)Ph radical over catalyst and the high energy barrier of over-oxidation of <img>CH(OH)Ph into benzaldehyde contributes to the formation of highly selective coupling products.

Furthermore, a mechanistic model is proposed that elucidates the observed synergistic catalytic behavior based on experimental characterization and DFT calculations. This proposed model is termed “Nanoparticles with Cluster and Single Metal Sites”(NCS mechanism). The retention of the Bi cluster structure within the material matrix plays a pivotal role in enhancing the adsorption and activation of formaldehyde.
