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.

ChemSusChem, Год журнала: 2024, Номер unknown

Опубликована: Июль 10, 2024

Abstract The rampant exploitation of fossil fuels has led to the significant energy scarcity and environmental disruption, affecting sound momentum development progress human civilization. To build a closed‐loop anthropogenic carbon cycle, biofuels employing sustainable biomass feedstocks stands at forefront advancing neutrality, yet its widespread adoption is mainly hampered by high production costs. Montmorillonite, however, garnered considerable attention serving as an efficient heterogeneous catalyst ideal economic feasibility for biofuel production, primarily due affordability, accessibility, stability, excellent plasticity. Up now, nevertheless, it merely received finite concerns interests in various using montmorillonite‐based catalysts. There no timely comprehensive review that addresses this latest relevant progress. This fills gap providing systematically summary controllable synthesis, performance enhancement, applications related different kinds including biodiesel, biohydrogenated diesel, levulinate, γ ‐valerolactone, 5‐ethoxymethylfurfural, gaseous (CO, H 2 ), cycloalkane, montmorillonite catalysts modified forms. Particularly, critically depicts design strategies montmorillonite, illustrates reaction mechanisms, assesses their viability, realizing via valorization. Overall, may offer valuable insights into cost‐effective proposes strategic recommendations advancement future development.
