abstract = {Light-driven photocatalytic conversion of biomass-derived substrates into
value-added chemicals, coupled with hydrogen (H2) evolution, offers a
promising route for solar energy utilization and sustainable chemical
production. However, achieving high efficiency and selectivity in such
dual-functional systems remains a challenge. Herein, the rational construction
of a hierarchical Au/Zn3In2S6/Co3O4 (Au/ZIS/Co3O4) photocatalyst is
reported for selective dehydrogenation of 5-hydroxymethylfurfural (HMF) to
2,5-diformylfuran (DFF), coupled with H2 generation. The unique
dual-interfacial electric fields at the Au/ZIS and ZIS/Co3O4 interfaces enable
directional and spatially separated migration of photogenerated electrons and
holes to Au and Co3O4, respectively. As a result, Au/ZIS/Co3O4 achieves a
remarkable H2 evolution rate of 2012.4 µmol g−1 h−1, with 67.2% of DFF yield
and excellent recyclability, which is 7.7 times higher than blank Zn3In2S6
(260.4 µmol g−1 h−1). This H2 yield rate is the highest among reported
photocatalysts for concurrent HMF valorization and H2 production.
Furthermore, the intrinsic quantum efficiency of the system is quantitatively
evaluated for the first time by solving the radiative transfer equation in a
tubular photoreactor. This work demonstrates a generalizable strategy for
engineering redox-site-separated photocatalysts for biomass valorization and
solar hydrogen production, offering valuable insights into the design
principles of next-generation photocatalytic systems for sustainable energy.},
