Increasing photocatalytic efficiency by photothermal effect |
| 초록 |
Photocatalytic reactions in which the semiconductor material absorbs light and affects the chemical reaction rate include hydrogen production by water decomposition, fuel production by reduction reaction of carbon dioxide, and decomposition and removal of toxic pollutants in fine dust and wastewater. Thermodynamic major factors which include photocatalytic energy level and band gap and kinetic major factors which include reactant concentration, light intensity, reaction temperature affect the photocatalytic reaction. In this study, we fabricated nanohybrid composite fibers that contained conjugated polymer nanoparticles (CPNs) with photothermal property inside the fibers and porous silver nanoshells. Photocatalytic effects of the silver nanoshells was dramatically increased by synergetic effects of enhanced light harvesting followed by efficient energy transfer and photothermal temperature increase. |
