Summary
Photocatalysis offers a sustainable route to harness solar energy for clean-energy production and pollution control, addressing two of the most pressing challenges of our time: energy transition and water/environmental security. Advances in functional materials now make it possible to drive solar-to-fuel conversion and the destruction of persistent pollutants under mild, light-driven conditions.
This Special Issue focuses on the rational design of advanced photocatalysts and their applications across the energy-environment nexus. We welcome original research and reviews on porous frameworks (MOFs, COFs) and polymeric semiconductors, magnetic and magnetically recoverable photocatalysts, and carbon-based hybrids.
Suggested themes include:
(i) photocatalytic and photoelectrochemical hydrogen evolution and water splitting;
(ii) CO2 photoreduction to solar fuels;
(iii) photocatalytic degradation of antibiotics, dyes, and emerging contaminants;
(iv) S-scheme/Z-scheme heterojunction engineering;
(v) structure-activity relationships, in-situ/operando studies, and mechanistic insights;
(vi) scalable, recyclable, and stable photocatalyst design.
