Subsurface Ce dopants in Bi₂MoO₆ monolayers as promoters for photocatalytic C‐N coupling reaction

AIChE Journal, Journal Year: 2025, Volume and Issue: unknown

Published: May 9, 2025

Abstract Understanding the role of subsurface dopants in photocatalysis is still highly challenging, although doping has always been one universal strategies for improving photocatalytic performance. Herein, Ce‐doped Bi 2 MoO 6 monolayers were prepared C–N coupling reaction. Effects Ce on investigated deeply via a series characterizations and density functional theory calculations. Especially, facilitates migration photogenerated electrons enhances adsorption nitrobenzene. Ce‐induced oxygen vacancies promote formation more frustrated Lewis acid–base pairs (Mo/O), facilitating benzyl alcohol. It establishes efficient pathways transfer carriers to reactants. Thus, typical (0.04 mmol)‐doped exhibited nitrobenzene conversion 94.5% secondary amine selectivity 99.1%. This work focuses photocatalysis, providing new insights design high‐efficiency photocatalysts investigation structure–function relationships.

Transformation of a Polyoxometalate Precursor into Carbon Doped Bismuth Molybdate Nanosheets for the Visible Light Photocatalytic Degradation of Aqueous Pollutants

ACS Applied Nano Materials, Journal Year: 2024, Volume and Issue: 7(15), P. 17596 - 17610

Published: Aug. 1, 2024

Heterogeneous photocatalysis is a convenient and effective tool for eliminating toxic organic effluents from the textile pharmaceutical industries. The analogous photocatalytic properties of polyoxometalates (POMs) with metal oxide-based semiconductors make them applicable wastewater treatment applications. However, high aqueous solubility low coverage visible solar spectrum limit wider applicability traditional POMs as heterogeneous photocatalysts. Herein, we report, first time, hydrothermal transformation UV-active polyoxometalate precursor, (C16H36N)4[Mo8O26] abbreviated TBA-Mo8, into light active carbon-doped Bi2MoO6 nanosheets (C-BMO) in presence Bi3+ salt studied its catalytic activities toward degradation dye pollutant, malachite green (MG), ciprofloxacin (CF). For comparison purposes, an undoped (U-BMO) nanosheet was also prepared under identical conditions starting situ generated POM precursor H4[Mo8O26]. successful TBA-Mo8 H4[Mo8O26] photocatalysts confirmed through series analytical spectroscopic techniques, including Fourier transform infrared, Raman, X-ray photoelectron spectroscopy, diffraction, scanning electron high-resolution transmission other analyses. results experiments revealed superior C-BMO compared to U-BMO parent cluster irradiation. achieved 70 87% MG CF irradiation against 29 35% degradation, respectively, shown by U-BMO. A plausible reason higher activity better charge separation due band gap modification resulting carbon doping. detailed pathways have been proposed based on scavenger studies ESI-MS analyses products. This work, therefore, summarizes how simple can serve precursors developing more efficient milder experimental procedures.
