In order to study the process of doping carbon into TiO2 without external carbon precursor, photocatalysts with different amount of doped carbon were prepared by heating the xerogel obtained by simple sol-gel method at different temperatures. After fitting and analyzing the peaks of XPS spectra of N 1s, C 1s, Ti 2p, O 1s, it is found that the variation trend of the amounts of doped carbon with temperature...
With the purpose to investigate the effect of heating temperature on the visible-light photocatalytic activities of carbon-doped TiO2, TiO2 photocatalysts doped with different amounts of carbon were synthesized through heating the dried gel at different temperatures from 70 to 350 °C. XRD, XPS, UV-Vis analysis were used to characterize the photocatalysts. The photocatalysts are all of anatase phase...
