Herein, a novel CdIn2S4/In2O3 heterojunction photocatalyst, aiming to enhance photocatalytic performance for pollutant degradation, is fabricated by a self‐assembly process at low temperature. Ternary CdIn2S4 nanoparticles are uniformly deposited on the In2O3 nanoflowers, forming a step‐scheme (S‐scheme) hybrid heterostructure. As a result, the light absorption efficiency and charge separation efficiency of CdIn2S4/In2O3 are greatly improved. Among these fabricated samples are activated by visible light, and the degradation efficiency of gaseous acetone is as great as 92.3% over 10% CdIn2S4/In2O3 within 3 h, which is the highest value observed. Furthermore, the key intermediate compounds are elucidated using in situ Fourier transform infrared (FTIR) spectra, which strongly validate the hypothesized light degradation mechanism over CdIn2S4/In2O3. Correspondingly, a potential photocatalytic mechanism over CdIn2S4/In2O3 S‐scheme heterojunction is explored and discussed.

“…Second, the separation and transfer efficiency of photoinduced charge carriers mainly depends on the recombination and mobility of photogenerated electrons and holes inside semiconductors [64][65][66]. If the lifetime and diffusion distance of photoexcited charge carriers are longer and larger, respectively, it is easier to separate and transport the carriers, leading to the higher process efficiencies.…”

Solar-driven photoelectrochemical (PEC) water splitting systems are highly promising for converting solar energy into clean and sustainable chemical energy. In such PEC systems, an integrated photoelectrode incorporates a light harvester for absorbing solar energy, an interlayer for transporting photogenerated charge carriers, and a co-catalyst for triggering redox reactions. Thus, understanding the correlations between the intrinsic structural properties and functions of the photoelectrodes is crucial. Here we critically examine various 2D layered photoanodes/photocathodes, including graphitic carbon nitrides, transition metal dichalcogenides, layered double hydroxides, layered bismuth oxyhalide nanosheets, and MXenes, combined with advanced nanocarbons (carbon dots, carbon nanotubes, graphene, and graphdiyne) as co-catalysts to assemble integrated photoelectrodes for oxygen evolution/hydrogen evolution reactions. The fundamental principles of PEC water splitting and physicochemical properties of photoelectrodes and the associated catalytic reactions are analyzed. Elaborate strategies for the assembly of 2D photoelectrodes with nanocarbons to enhance the PEC performances are introduced. The mechanisms of interplay of 2D photoelectrodes and nanocarbon co-catalysts are further discussed. The challenges and opportunities in the field are identified to guide future research for maximizing the conversion efficiency of PEC water splitting.
