Synthesis of Double Helix-like Ag2CO3/Ag2O Rods for Sunlight-driven Photocatalyst and NIR-Triggered Drug Delivery System |
| 초록 |
The ellipsoidal or rod-like Ag2CO3 nanostructures were synthesized by a facile precipitation reaction in the presence of PVP. The resulting Ag2CO3 nanostructures were transformed into the Ag2CO3/Ag2O nanostructures by controlled heat treatment. During the heat treatment, both of Ag2CO3 nanostructures were changed into double helix-like microrods by fusion of individual nanostructure. Double helix-like Ag2CO3/Ag2O microrods (DHAgMRs) with high specific surface area exhibited a strong absorption band in the range of visible (vis) to near infrared (NIR) regions, meaning that the catalytic property of the DHAgMRs can be activated by the sunlight. After synthesis of mesoporous SiO2 layer on the DHAgMRs, we expect that the resulting DHAgMR/SiO2 can be used as a drug delivery carrier triggered by NIR irradiation as well. |
