Special Issue Information

Dear Colleagues,

Because of the long implementation of the linear economy, our world is facing two serious challenges involving environmental pollution and the need for clean and renewable energy sources. The scientific and industrial communities, nowadays, are seeking to develop sustainable technologies for environmental remediation and energy production within the circular economy concept. One of these technologies, solar photocatalysis, has been involved in many related research areas. The objective of this SI is to address the recent advances in photocatalytic technology towards environmental remediation and energy production. Topics of interest include, but are not limited to, the following:

  • Design of innovative and effective photocatalytic materials and reactors for energy and environmental applications;
  • Developing photocatalytic materials to boost the valorisation of biomass into high value products;
  • Novel discussion of lignin conversion by photocatalysis;
  • Advances in H2 generation from biomass and wastewaters;
  • Design of novel solar materials for steam production and water desalination;
  • Combination of photocatalysis with other technologies for enhanced environmental remediation and energy production.

The development of efficient and sustainable photocatalysts for wastewater treatment remains a critical challenge in environmental remediation. In this study, a ternary photocatalyst, Cu-Cu2O/g-C3N4, was synthesized by embedding copper-copper oxide heterostructural nanocrystals onto g-C3N4 nanosheets via a simple deposition method. Structural and optical characterization confirmed the successful formation of the heterostructure, which combines the narrow bandgap of Cu2O, the high stability of g-C3N4, and the surface plasmon resonance (SPR) effect of Cu nanoparticles. The photocatalytic performance was evaluated through the degradation of Rhodamine B (RhB) in a photo-Fenton-like reaction system under visible light irradiation. Among the catalysts tested, the 30 wt% Cu-Cu2O/g-C3N4 composite exhibited the highest catalytic efficiency, achieving a reaction rate constant approximately 3 times and 1.5 times higher than those of Cu-Cu2O and g-C3N4, respectively. Mechanistic studies suggest that the heterostructure facilitates efficient charge separation and promotes the reduction of Cu2+ to Cu+, thereby enhancing ∙OH radical generation. The catalyst also demonstrated excellent stability and reusability across a wide pH range. These findings provide a new strategy for designing highly efficient photocatalysts for organic pollutant degradation, contributing to the advancement of advanced oxidation processes for environmental applications.
