Hydrochar-Supported NiFe2O4Nanosheets with a Tailored Microstructure for Enhanced CO2Photoreduction to Syngas

“…49,50 The transient photocurrents of C/NFO were much stronger than those of the pure NFO (Figure S7), also suggesting a significant enhancement on the generation and migration of photogenerated charge in C/NFO. 51 These results and discussions collectively support the idea that the reduced charge recombination rate and enhanced charge transfer ability are the key factors contributing to the improved photocatalytic activity for the 16%-C/NFO composite.…”

“…The catalytic role of C/NFO in the CO 2 photoreduction system was demonstrated by measuring the in situ fluorescence spectra. As depicted in Figure a, compared to the pure Ru­(bpy) 3 2+ system, the inclusion of C/NFO led to a decrease in photoluminescence (PL) intensity, indicating its effective suppression of charge carrier recombination by facilitating electron transfer from the photosensitizer and thereby enhancing photocatalytic performance for CO 2 reduction. , Additionally, the electrochemical impedance measurement results (Figure b) revealed that the 16%-C/NFO composite exhibited the smallest impedance among these C/NFO catalysts, indicating its more efficient transfer kinetics of photoexcited electrons and holes. , The transient photocurrents of C/NFO were much stronger than those of the pure NFO (Figure S7), also suggesting a significant enhancement on the generation and migration of photogenerated charge in C/NFO .

Recent progress in metal halide perovskite photocatalysts for hydrogen evolution

“…139 Both S-type and Ztype heterostructures effectively promote charge transfer without compromising the respective oxidation and reduction capabilities of the two semiconductors, garnering considerable research interest in recent years. [140][141][142][143] Meanwhile, the redox reaction is separated in space, and it is therefore expected to achieve an efficient overall water splitting through the appropriate medium and test system. 77 In order to improve the hydrogen production performance of MHP-based photocatalysts, various composite structures have been constructed, such as black phosphorus/MAPbI 3 I heterojunction, 116 MAPbI 3 /MoS 2 II heterojunction, 131 etc.…”

Photocorrosion-Resistant ZnCo2S4/CdS Z-Scheme Heterojunction for Efficient Co-production of Aromatic Aldehydes and Hydrogen

“…Z-scheme heterojunction photocatalysts can maintain high reduction and oxidation activity of photogenerated carriers in a dual-band under the simultaneous excitation of two photons, thereby resulting in an enhanced overall utilization efficiency of solar energy. Constructing a Z-scheme heterojunction by coupling CdS with an energy-level-matched semiconductor can greatly promote the separation of photogenerated charges, thereby inhibiting the photocorrosion of CdS by h + off-migration. − However, due to the kinetically sluggish 4e – process of oxygen evolution reaction (OER), , h + cannot be consumed and depleted timely from the CdS surface, leading to photocorrosion.…”
