The development of new strategies to improve reaction efficiency and light utilization is one of the biggest challenges in photosynthetic chemistry. Dynamics control, in particular, tuning the adsorption/desorption of reactants and products is an ideal way to improve the conversion and selectivity in a catalytic reaction, but it is rarely studied in photocatalytic organic synthesis. Here, we designed an amorphous FeOOH coating to decorate the CdS photocatalyst to control the adsorption/desorption of reactants and products to improve reaction efficiency. The best conversion of the core-shell photocatalyst reaches up to 74.1% in 2 h together with >99.9% selectivity, and the photocatalyst responses above 600 nm, which is the longest active wavelength reported for the reaction. Further data illustrate that amorphous FeOOH coating enables selective sorption of BA/BAD molecules by H-bonding induced interaction, which may result in the excellent performance. Construction of amorphous coating layers and understanding the selective permeability may provide a new strategy for design more efficient photocatalytic system for organic synthesis.
