Abstract: | Cu/TiO2 facilely synthesized from TiC13 by aerosol - spraying preparation. XRD, UV - vis spectroscopy, N2 adsorption, XP spectra were used to characterize the prepared samples. The existence of Cu ions in the anatase TiO2 sample was demonstrated. The 2% Cu/TiO2 exhibited the best photocatalytic activity for nitrate reduction. The nitrate conversion was up to 31%, and the selectivity of N2 was 56% after reaction for 240 min. |
