“…The cliff-like conduction band offset (CBO) in CuSbS 2 (CAS)/ZnO was modified by coupling another material, CdS, to form spike-like CBO, resulting in a reduced interface combination rate and increased photocatalytic efficiency. The CAS-ZnO-CdS heterojunction prepared by the microwave-assisted method produced a hydrogen evolution of 140.45 µmol/g after 4 h of illumination [58]. A combination of solvothermal and electrospinning technology was used for preparing CuBi 2 O 4 -Bi 2 WO 6 nanofibres with Z scheme heterojunction with a 90% degradation efficiency of tetracycline hydrochloride [59].…”

Environmental pollution poses a pressing global challenge, demanding innovative solutions for effective pollutant removal.. Photocatalysts, particularly titanium dioxide (TiO2), are renowned for their catalytic prowess; however, they often require ultraviolet light for activation. Researchers had turned to doping with metals and non-metals to extend their utility into the visible spectrum. While this approach shows promise, it also presents challenges such as material stability and dopant leaching. Co-doping, involving both metals and non-metals, has emerged as a viable strategy to mitigate these limitations. Inthe fieldof adsorbents, carbon-based materials doped with nitrogen are gaining attention for their improved adsorption capabilities and CO2/N2 selectivity. Nitrogen doping enhances surface area and fosters interactions between acidic CO2 molecules and basic nitrogen functionalities. The optimal combination of an ultramicroporous surface area and specific nitrogen functional groups is key to achievehigh CO2 uptake values and selectivity. The integration of photocatalysis and adsorption processes in doped materials has shown synergistic pollutant removal efficiency. Various synthesis methods, including sol–gel, co-precipitation, and hydrothermal approaches had been employed to create hybrid units of doped photocatalysts and adsorbents. While progress has been made in enhancing the performance of doped materials at the laboratory scale, challenges persist in transitioning these technologies to large-scale industrial applications. Rigorous studies are needed to investigate the impact of doping on material structure and stability, optimize process parameters, and assess performance in real-world industrial reactors. These advancements are promising foraddressing environmental pollution challenges, promoting sustainability, and paving the way for a cleaner and healthier future. This manuscript provides a comprehensive overview of recent developments in doping strategies for photocatalysts and adsorbents, offering insights into the potential of these materials to revolutionize environmental remediation technologies.
