“…Tauc plots revealed that their optical band gap energies, 2.35 and 1.63 eV, respectively, were consistent with those found in the literature studies. 29,38 In addition, the Mott−Schottky plots (Figures S4a,b) demonstrated that CuO is a p-type semiconductor, whereas branching BiVO 4 is an n-type semiconductor. BiVO 4 and CuO samples had flat band potentials (E fb ) of approximately −0.22 and −0.43 eV, respectively (in contrast to normal hydrogen electrode (NHE), pH = 7.0).…”

The solar-driven transformation of lignin into aromatic compounds is a promising approach for biomass utilization. However, selective cleavage of lignin C–C bonds on the solid catalyst surface under suitable conditions is a difficult task. Here, a CuO/BiVO4 hybrid was reported for the selective oxidation of C–C bonds under simulated sunlight at room temperature. The synergistic effect of CuO and BiVO4 benefited charge dynamics and transfer from the photoexcitation sites to the active centers. The model substrate representing lignin β-O-4 linkages was converted into aromatic compounds with 86.5% C–C cleavage selectivity, and the aromatic compounds were produced with a yield reaching 665.03 μmol gcat –1·h–1. Mechanistic studies showed that Cα–Cβ bonds were efficiently cleaved mainly through hydrogen abstraction from the β-carbon by photogenerated holes and the generation of •O2 – from adsorbed O2 by photoexcited electrons. The result provided new views into the development of more efficient photocatalysts for the cleavage of lignin C–C bonds through interfacial engineering.

“…The increased photocurrent density of this new material indicates that it has a high ability to promote the formation and, transfer of and avoid the recombination of

pairs ( Faraji et al, 2019 ; Peter et al, 2020 ). In a more recent study, Mao et al (2022) prepared a CuO/BiOCl p-n type heterojunction for simultaneous photoelectrochemical detection and photoelectrocatalytic degradation of aflatoxin B1 (AFB1). The modification with CuO nanoparticles improved the responsivity of BiOCl and thus the photocurrent conversion.…”

Bismuth Oxyhalide-Based Materials (BiOX: X = Cl, Br, I) and Their Application in Photoelectrocatalytic Degradation of Organic Pollutants in Water: A Review

An important target of photoelectrocatalysis (PEC) technology is the development of semiconductor-based photoelectrodes capable of absorbing solar energy (visible light) and promoting oxidation and reduction reactions. Bismuth oxyhalide-based materials BiOX (X = Cl, Br, and I) meet these requirements. Their crystalline structure, optical and electronic properties, and photocatalytic activity under visible light mean that these materials can be coupled to other semiconductors to develop novel heterostructures for photoelectrochemical degradation systems. This review provides a general overview of controlled BiOX powder synthesis methods, and discusses the optical and structural features of BiOX-based materials, focusing on heterojunction photoanodes. In addition, it summarizes the most recent applications in this field, particularly photoelectrochemical performance, experimental conditions and degradation efficiencies reported for some organic pollutants (e.g., pharmaceuticals, organic dyes, phenolic derivatives, etc.). Finally, as this review seeks to serve as a guide for the characteristics and various properties of these interesting semiconductors, it discusses future PEC-related challenges to explore.
