Abstract:
We report our observation of solution photochemical reactions catalyzed by carbon nanotubes. Addition of sub-millimolar Ag+ ions into a solution of DNA-wrapped carbon nanotubes (DNA-CNT) leads to a strong charge-transfer band in the UV region of the optical absorption spectrum. Light irradiation of the Ag+/DNA-CNT mixture results in reduction of Ag+ to Ag nanoparticles and concomitant oxidation of water.
