Topic: Photocatalytic Strategies for Green Chemistry

The transition toward sustainable chemical processes has intensified the search for cleaner, safer, and more energy-efficient technologies. Photocatalysis has emerged as a transformative approach within green chemistry, offering the ability to drive chemical reactions using light-an abundant and renewable energy source. By enabling pollutant degradation, selective organic synthesis, CO₂ conversion, and wastewater purification under mild conditions, photocatalytic systems significantly reduce the reliance on toxic reagents, harsh reaction environments, and fossil-fuel-based energy inputs.

Recent advances in nanostructured semiconductors, plasmonic materials, metal-organic frameworks, and heterojunction architectures have dramatically enhanced photocatalytic efficiency and selectivity. These innovations open new avenues for sustainable synthesis pathways, circular chemical processes, and environmentally friendly remediation technologies. This special topic, Photocatalytic Strategies for Green Chemistry, aims to explore the latest breakthroughs, mechanistic insights, and practical applications of photocatalysis that support the global shift toward eco-responsible chemical engineering and environmental protection.
