“…Among the various technologies, photocatalysis is a safe and highly efficient technology that is attracting the attention of researchers (Xiong et al 2010;Vidhu and Philip 2014;Xu et al 2019). The widely used inorganic semiconductor photocatalysts include ZnO, TiO 2 , La 2 O 3 , Bi 2 O 3 , Fe 2 O 3 , CdS, ZnS, CuI and many more (Huo et al 2008;Zhao et al 2011;Chauhan et al 2013;Sookhakian et al 2013;Yadav et al 2019;Ji et al 2019;Mittal et al 2019;Abdelhamid 2020;Sharma et al 2021). Among these semiconductor materials, Bi 2 O 3 (bismuth oxide) is an adaptable material having band gap value of 2.8 eV (Chung et al 2018).…”

α-β Bi 2 O 3 modified with Cu 2+ ions in various compositions have been synthesized by hydrothermal process. The crystallinity, surface structure, elemental compositions and optical characteristics were uncovered by relevant techniques including XRD, SEM, EDX, XPS, PL, and UVDRS. Total organic carbon (TOC) analysis was performed to determine the dye degradation efficiency of photocatalyst. Highly crystalline Bi 2 O 3 nanoparticles consisting of α-β phase heterojunctions were observed possessing crystallite sizes in the range of 30-40 nm. The photocatalytic activity of Cu 2+ -modified Bi 2 O 3 composites was studied using RhB dye under the illumination of visible light. The results reveal that addition of Cu 2+ ions into Bi 2 O 3 lattice significantly improved the degradation rate over the pure sample. The highest activity was obtained for sample containing 2 mol % Cu in Bi 2 O 3 lattice where complete degradation of the pollutant was attained in 120 min. The increased activity is largely ascribed to the effective separation of charge carriers due to Cu 2+ doping and formation of α-β phase heterojunctions in Bi 2 O 3 .The effect of pH conditions and role of active species on degradation kinetics were also examined.

The presence of organics in water poses a serious risk to the environment, as well as to human health. It is important to develop effective water treatment techniques that are affordable, durable, and sustainable. The removal and degradation of organic matter in water is widely explored using 2D and 3D nanomaterials, which are advantageous in providing high surface to volume ratios and favorably photoelectro activity as compared to traditional materials. The robustness of nano semiconductors has made it highly sustainable in water treatment. This review concentrates on nanostructured materials, which are demonstrating the removal of pollutants from water using various 2D and 3D nanostructured materials as photoelectrocatalytic electrodes. The 2D and 3D nanostructured materials are divided into five types according to physical morphology: nanofilms/nanosheets, nanopore structure/nanonetwork, nanoflowers, nanotubes, and other forms. Apart from this, the preparation method, characterization technology, and photoelectrocatalytic efficiency of organic pollutants degradation are reviewed. Finally, the different factors influencing degradation of organic pollutants are discussed.
