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.

Опубликована: Март 3, 2025

Abstract The excessive use of fossil fuels has significantly increased environmental stress, driving the need for green, sustainable biofuel alternatives. Innovations in photocatalysis (PC), electrocatalysis (EC), and their synergistic approaches, like photothermal catalysis (PTC), photo‐enzymatic (PENC), photoelectrocatalysis (PEC), offer advanced methods biomass conversion into biofuels, surpassing traditional limitations. However, comprehensive research on these processes is still lacking. This review aims to systematically analyze recent progress catalytic strategies biomass‐to‐biofuel conversion. It first describes characteristics, types, properties biofuels. Then, it explores fundamental mechanisms PC, EC, combined technologies. chemical pathways involved conversion—such as transesterification, esterification, hydrogenation, decarboxylation, bond cleavage, cyclization—are examined. Efficient catalyst design specific reactions factors influencing efficiency rates are also discussed. Additionally, this paper assesses impact economic benefits green technology production, offering a valuable reference energy application. addresses challenges deployment production suggests future directions, aiming provide scientific guidance technical support development vital field. In summary, underscores importance continued innovation promote solutions.
