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.

Case Studies in Chemical and Environmental Engineering, Год журнала: 2024, Номер 9, С. 100698 - 100698

Опубликована: Март 19, 2024

In this study, an aqueous ammonia emulsion and a zinc sulfide/copper (ZnS/Cu) nanocomposite were blended with algae biodiesel-diesel blend, the optimum levels of parameters identified for enhanced performance reduced emissions. The cultivated concurrently wastewater treatment, biodiesel's properties as well nanocomposite's structural surface morphology analyzed. Response methodology was employed optimization, confirmation tests conducted. results indicate that cultivation effectively removes nutrients, optimal values process determined to be 10% biodiesel, 14% ammonia, 95 ppm ZnS/Cu.
