Synthesis of a three-phase heterojunction NdVO₄/V₂O₅/BiVO₄ by cation exchange method for the degradation of anionic azo dye orange II

Dalton Transactions, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 1, 2025

Photocatalytic degradation of the azo dye orange II using NdVO4/V2O5/BiVO4 under visible light is reported here, and this oxygen-rich defect three-phase heterojunction structure constructed a two-step cation exchange method. This significantly enhances separation migration efficiency photo-induced charges, while accompanying oxygen defects effectively capture photogenerated electrons, thereby suppressing recombination electrons holes. Experimental characterization theoretical calculations demonstrate efficient transfer capabilities carriers their excellent photocatalytic performance. Particularly, when treating anionic II, achieves up to 96.15%. Cycling tests show that NVB-24 exhibits good stability during reaction process. research provides promising photocatalyst for dyes offers new insights developing high-quality materials.

Graphene-Based Organic Semiconductor Film for Highly Selective Photocatalytic CO2 Reduction

Nanomaterials, Journal Year: 2025, Volume and Issue: 15(9), P. 677 - 677

Published: April 29, 2025

Mimicking artificial photosynthesis utilizing solar energy for the production of high-value chemicals is a sustainable strategy to tackle fossil fuel-based crisis and mitigate greenhouse effect. In this study, we developed two-dimensional (2D) graphene oxide (GO)–diketopyrrolopyrrole (DPP) film photocatalyst. GO nanosheets facilitate uniform dispersion DPP nanoparticles (~5 nm) while simultaneously constructing an efficient charge transport network carrier recombination. Under visible-light irradiation in aqueous solution without sacrificial agents, optimized GO–DPP50 catalyst exhibited exceptional performance, achieving CO rate 32.62 μmol·g⁻1·h⁻1 with nearly 100% selectivity. This represents 2.77-fold 3.28-fold enhancements over pristine (8.65 μmol·g−1·h−1) bare (7.62 μmol·g−1·h−1), respectively. Mechanistic analysis reveals synergistic mechanism. The 2D framework not only serves as high-surface-area substrate anchoring, but also substantially suppresses recombination through rapid electron channels. Concurrently, uniformly distributed improve absorption efficiency effective photogenerated excitation. work establishes novel paradigm integration nanomaterials organic semiconductors, providing critical design principles developing high-performance film-based photocatalysts selectivity control CO2 reduction applications.

Chemistry - A European Journal, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 2, 2024

Abstract The utilization of CO 2 , H O, and solar energy is regarded as a sustainable route for converting into chemical feedstocks, paving the way carbon neutrality reclamation. However, simultaneous photocatalytic reduction O oxidation under non‐sacrificial ambient conditions still significant challenge. Researchers have carried out extensive exploration achieved dramatic developments in this area. In review, we first primarily elucidate principles two half‐reactions conversion with i. e., by photo‐generated electrons protons, holes without sacrificial agents. Subsequently, strategies to promote are summarized, including vacancy/facet/morphology design, adjacent redox site construction, Z‐scheme heterojunction development. Finally, present advanced situ characterizations future perspectives field. This review aims provide fresh insights effectively conditions.
