| 제목 | Modulating Photocatalytic Activity of ZnO/Au Hybrid Systems via Thermoresponsive Polymer Linkers |
| 초록 | It has been investigated that the surface plasmon resonance (SPR) can improve the efficiency of photocatalytic activity and the effect is extremely sensitive to the distance between the constituent elements, which is exploited in Plasmon ruler. Poly(N-isopropylacrylamide) (PNIPAM) undergoes a reversible phase transition at a lower critical solution (LCST) of about 32 ℃ in pure water from a swollen state to a shrunken state. In this work, PNIPAM brushes were anchored on the Au film by atom transfer radical polymerization and ZnO nanoparticles were immobilized on PNIPAM for controlled photocatalytic activity. We demonstrate that the photocatalytic activity was influenced by various features such as the synthesis conditions, grafting density and molecular weight of PNIPAM involved in the ZnO-PNIPAM-Au film. Changing the distance between Au films and ZnO nanoparticles with respect to the temperature led to plasmonic-coupling-controlled photophysical properties. Finally, we observe different plasmonic effects in terms of the degradation of organic pollutants. |
