S-scheme Porous g-C3N4/Ag2MoO4 Heterojunction Composite for CO2 Photoreduction
文献摘要：
Utilizing solar energy to achieve artificial photosynthesis of chemical fuel is prevalent in tackling excessive CO2 emission and fossil fuel depletion. Grievous charge recombination and weak redox capability aggravate the CO2 photoreduction performance. Engineering tailored morphology and constructing matched heterostructure are two significant schemes to ameliorate the CO2 photoconversion efficiency of g-C3N4-based composite. Herein, a novel S-scheme ultrathin porous g-C3N4 (UPCN)/Ag2MoO4 (AMO) composite was designed by in-situ growing te-tragonal α-AMO nanoparticles (NPs) (5-30 nm) on UPCN nanosheets (NSs). The S-scheme charge transfer route endows UPCN/AMO with fast charge separation and strong redox capability, demonstrated by X-rayphotoelectron spectroscopy (XPS), photoelectrochemical tests, steady-state and time-resolved photoluminescence (PL) spectra, and DFT calculations. The UPCN/AMO composite exhibits elevated CO2 photoreduction performance with CO and CH4 yield rates of 6.98 and 0.38 μmol g-1 h-1, which are 3.5 and 2.9 folds higher than that of pristine UPCN, respectively. Finally, the CO2 photoreduction intermediates are analyzed, and the CO2 photoreduction mechanism is discussed. This work provides a reference for various g-C3N4-based composites applied in artificial photosynthesis.
