Bulk and surface modified polycrystalline CuWO4 films for photoelectrochemical water oxidation

Jin Uk Lee et al.

Summary: Polycrystalline CuWO4 film is a promising photoanode material for PEC water splitting due to its small bandgap and excellent stability. However, its poor charge transfer characteristics limit its PEC performance. To improve the performance, two modification strategies are employed, using SnO2 as an electron transfer layer and cobalt phosphate as a co-catalyst. These modifications enhance the PEC activity by two times and exhibit excellent stability in a neutral electrolyte. Further developments of synthesis method and other modification strategies could potentially improve the performance.

Recent developments in photocatalysis of industrial effluents : A review and example of phenolic compounds degradation

Mahsa Motamedi et al.

Summary: Industrial expansion and increased water consumption have led to water scarcity issues, while conventional wastewater purification methods are not efficient in degrading stubborn pollutants. This review paper discusses recent advances and challenges in using photocatalytic processes for treating industrial effluents, particularly in degrading phenolic compounds. Key operational parameters, such as catalyst loading, light intensity, initial pollutant concentration, pH, and types and concentrations of oxidants, are evaluated and discussed. Among these parameters, pH has the greatest effect on the photo-oxidation of contaminants due to the photocatalyst's ionization degree and surface charge. The review also presents major phenolic compounds and explores the applicability and barriers of photocatalytic processes in practical applications, including high energy demand, technical challenges, catalyst stability, and recyclability. Energy consumption and operational costs for large-scale processes are also discussed. Finally, research gaps in this area and suggestions for improving degradation efficiencies in industrial applications are presented, including the proposal for selective degradation processes in untreated sewage.

Pollution and health: a progress update

Richard Fuller et al.

Summary: The Lancet Commission on pollution and health reported that pollution was responsible for 9 million premature deaths in 2015, making it the world's largest environmental risk factor for disease and premature death. Updated data from 2019 shows that pollution is still responsible for approximately 9 million deaths per year, with reductions in some types of pollution offset by increases in others. Despite efforts, little progress has been made in addressing pollution, particularly in low-income and middle-income countries.

Summary: In this work, a Z-scheme Bi2S3-Bi2WO6 heterojunction with interfacial Bi-S bonds was constructed. The obtained BS-BWO heterojunction exhibited significantly enhanced piezocatalytic performance, which could be attributed to the Z-scheme charge transfer through the formed Bi-S bonds. The increased piezoelectric potential of BS-BWO also contributed to the enhanced piezocatalytic performance, as supported by COMSOL simulation.
