Phys.org  December 17, 2024 The synergistic integration of all the components for efficient light harvesting, cascade electron transfer, and efficient biocatalytic reactions presents a formidable challenge. Researchers in the UK described the bottom-up construction of a visible-light-driven chemical–biological hybrid nanoreactor with augmented photocatalytic efficiency by anchoring an α-carboxysome shell encasing on the surface of a hydrogen-bonded organic molecular crystal, a microporous α-polymorph of tetra(4′-carboxyphenyl)pyrene (TBAP-α). Within this hybrid photobiocatalyst, TBAP-α functioned as an antenna for visible-light absorption and exciton generation, supplying electrons for hydrogen production by H–S in aqueous solutions. This coordination allowed the hybrid nanoreactor to execute hydrogen evolution […]
