S‑Scheme Photocatalyst NH<sub>2</sub>–UiO-66/CuZnS with Enhanced Photothermal-Assisted CO<sub>2</sub> Reduction Performances
Green
and mild sunlight-driven photocatalysis has emerged as a
promising technology for mitigating climate- and energy-related issues.
In CO2 reduction reactions, metal–organic framework
(MOF) materials are often compounded with inorganic semiconductor
ZnS to form S-scheme photocatalysts that facilitate effective charge
migration and separation across the composite interface. However,
the large bandwidth of unmodified or modified ZnS remains a major
hurdle in achieving efficient photocatalytic reactions. Therefore,
this study aimed to reduce the band gap width of ZnS by incorporating
Cu-doped ZnS(en)0.5 (CuZnS) as the inorganic semiconductor
substrate and NH2–UiO-66 as the organometallic framework
material to prepare NH2–UiO-66/CuZnS composite photocatalysts,
ultimately realizing a thermally assisted photocatalytic CO2 reduction reaction. With the help of photothermal conversion from
CuZnS, the temperature of CO2 reduction increased to 54.2
°C, resulting in a fast kinetic showing an improved yield of
22.85 μmol g–1 h–1 via the
photocatalytic route
