This special topic volume on 鈥淧hotocatalytic materials and surfaces for environmental cleanup IV鈥?addresses photocatalysis in wide sense focus on the environmental applications of photocatalytic materials. Photocatalytic materials had been widely studied for the various applications such as water and air purification, CO2 reduction, hydrogen generation, and development of auto-cleaning surfaces etc. The present special topic volume covers the application of various photocatalytic materials for CO2 reduction, hydrogen generation, removal of pesticides, degradation of organic pollutant and recent development in the fabrication of photocatalytic reactors.
