Photocatalytic Conversion of Lipid to Diesel and Syngas via Engineering the Surface Proton Transfer

ACS Catalysis, Journal Year: 2024, Volume and Issue: 14(3), P. 1699 - 1705

Published: Jan. 17, 2024

Photocatalysis provides a promising pathway for the production of fuels and chemicals from biomass, where slow proton reduction by surface-confined photoinduced electrons limits efficiency. Herein, we propose to engineer surface structure facilitate transfer on catalyst thus promote confined electrons. We found introducing NH4+ TiO2 (NH4–TiO2) could improve conductivity. The group effectively minimizes distance promotes forming hydrogen-bond networks. Consequently, NH4–TiO2 shows high yield (≥80%) alkanes bio-derived fatty acids which is about 3.8 times that pristine TiO2. Glycerol can be reformed syngas with generation rate [CO (0.69 mmol g–1 h–1)/H2 (0.21 h–1)]. Moreover, industrial palm oil converted into 59% [4% CO H2 (0.04 h–1)] via hydrolysis-photocatalysis two-step process. This work an efficient approach biomass upgrading rationally controlled

Photocatalysis coupling of H2 evolution and lignocellulose oxidation remain great foreground, but slow photodynamic process limits its development. Here, we explored the effect defect engineering on electronic structure d-band center Pt/TiO2 catalyst. Oxygen vacancies lead to delocalization electrons near O atom, moves down, which will redistribute facilitate desorption intermediates The density functional theory results indicate that Pt TiO2 surfaces form electron-rich electron-deficient regions, respectively. Meanwhile, in situ electron paramagnetic resonance shows thermal energy accelerated generation free radicals. Thus, rate lignin derivative conversion were effectively facilitated. Especially, efficiency thermo-photo reforming can reach 989.7 μmol g–1 h–1, is 18.2 times photo reforming. This work not only delves deeply into modulation defect-type catalysts also offers new insights efficient utilization lignin-based biomass.
