Regulating the transfer pathway of charge carriers in heterostructure photocatalysts is great importance for selective CO2 photoreduction. Herein, and turn redox potential succeeded to regulate 2D MoS2 /1D TiO2 by varying light wavelength range. Several situ measurements experiments confirm that follows either an S-scheme mechanism under simulated solar irradiation or a heterojunction approach visible illumination, elucidating switchable property /TiO2 heterostructure. Replacing sunlight...
The hydrothermal dissolution-recrystallization process is a key step in the crystal structure of titania-based nanotubes and their composition. This work systematically studies conditions for directly synthesizing anatase TiO2 (ATNTs), which have not been deeply discussed elsewhere. It has well-known that ATNTs can be synthesized by calcination titanate nanotubes. Herein, we found optimizing reaction temperature time rather than nanotubes, where at each temperature, there range times...
Switching between the redox potential of an appropriate semiconductor heterostructure could show critical applications in selective CO 2 reduction. Designing a photocatalyst with wavelength‐dependent response is effective strategy for regulating direction electron flow and tuning potential. Herein, switching mechanism two charge migration pathways potentials Bi S 3 /TiO /MoS by light wavelength achieved. In situ irradiated X‐ray photoelectron spectroscopy (ISI‐XPS), spin resonance (ESR),...

Abstract Combination of plasmonic noble metal with semiconductors offers a promising and potential solar energy harvesting conversion route. Herein, Z‐scheme Ag‐Bi 2 O 3 ‐ZnO (AgBZ) heterostructure is designed synthesized via solution combustion photo‐deposition method. Metallic Ag nanoparticles (NPs) were deposited over Bi heterostructure; thus, they exhibit strong visible light absorption owing to surface plasmon resonance (SPR). The photocatalytic efficiency the catalysts investigated by...
CO2 Reduction In article number 2100501, Lokanath Neratur Krishnappagowda and co-workers found that the Bi2S3/TiO2/MoS2 photocatalyst shows a different response to wavelengths. Under UV-vis-NIR irradiation, electron migration follows S-scheme system, while under Vis-NIR type-II heterojunction, resulting in wavelength-dependent selectivity for photocatalytic reduction products.
