Large-scale synthesis and enhanced visible-light-driven photocatalytic performance of hierarchical Ag/AgCl nanocrystals derived from freeze-dried PVP–Ag+ hybrid precursors with porosity

(Z)-Cinnamate derivatives are prevalent in natural bioactive products and in organic synthesis. Herein, we report a practical approach toward the efficient synthesis of (Z)-cinnamate derivatives via visible-light-driven isomerization. When E-isomers of cinnamate derivatives were irradiated with blue light in the presence of 1 mol% Ir2(ppy)4Cl2 (ppy = 2-phenylpyridine), Z-isomers were readily obtained in good yields. This strategy allows the large-scale synthesis of (Z)-cinnamate derivatives with simple purification. This convenient, mild, and green synthetic methodology was subsequently applied to the synthesis of coumarins.

Poor Stability

Visible-light-driven hydrogen production through photocatalysis has attracted enormous interest owing to its great potential to address energy and environmental issues. However, photocatalysis possesses several limitations to overcome for practical applications, such as low light absorption efficiency, rapid charge recombination, and poor stability of photocatalysts. Here, the preparation of efficient noble metal–semiconductor hybrid photocatalysts for photocatalytic hydrogen production is presented. The prepared ternary Rh–TiO2–CeO2 hybrid photocatalysts exhibited excellent photocatalytic performance toward the hydrogen production reaction compared with their counterparts, ascribed to the synergistic combination of Rh, TiO2, and CeO2.
