Semiconductor-based photocatalytic reactions are a practical class of advanced oxidation processes (AOPs) to address energy scarcity and environmental pollution. By utilizing solar as clean, abundant, renewable source, this process offers numerous advantages, including high efficiency, eco-friendliness, low cost. In review, we present several methods construct various photocatalyst systems with excellent visible light absorption efficient charge carrier separation ability through the optimization materials design reaction conditions. Then it introduces fundamentals photocatalysis in both clean generation remediation. other parts, introduce approaches enhance activity by applying different strategies, semiconductor structure modification (e.g., morphology regulation, co-catalysts decoration, doping, defect engineering, surface sensitization, heterojunction construction) tuning optimizing conditions (such concentration, initial contaminant pH, temperature, intensity, charge-carrier scavengers). Then, comparative study on performance recently examined photocatalysts applied production remediation will be discussed. To realize these goals, H2 via water splitting, CO2 reduction value-added products, dye, drug photodegradation lessen toxic chemicals, presented. Subsequently, report dual-functional for simultaneous pollutant reactions. brief discussion about industrial economical applications is described. The follows introducing application artificial intelligence machine learning selection an innovative issues. Finally, summary future research directions toward developing significantly improved efficiency stability provided.

Abstract The rational design of a photocatalyst and its microenvironmental modulation is crucial in the heterogeneous photocatalysis process, yet relevant research on photocatalytic biodiesel synthesis not explored. Herein, based prediction density functional theory (DFT) calculations, highly efficient ternary biocompatible montmorillonite (Mt) nanocomposites S‐scheme heterojunction photocatalysts (g‐C 3 N 4 ‐TiO 2 @Mt, CTM) are successfully rationally designed. By modulating microenvironment production, CTM‐2 demonstrates exceptional catalytic performance stability, achieving record‐breaking yield 98.5%. Through ex/in situ X‐ray photoelectron spectroscopy (XPS), absorption near‐edge (XANES), theoretical formation revealed, which can generate an interface electric field (IEF) that provides intrinsic driving force for carrier migration enhances surface positivity. This boosts enrichment effect electronegative oleic acid (OA) carboxyl molecules, thus greatly enriching substrate concentration improving reaction microenvironment. Moreover, fourier transform infrared spectrometer (FT‐IR)/Raman together with electron paramagnetic resonance (EPR) further confirm key intermediates CH O• ester carbonyl (C═O), DFT calculations provide reference pathway, determined to be capable significantly reducing energy barrier rate‐determining step.
