Abstract: In order to develop a new kind of bamboo charcoals, photocatalytic degradation with modified bamboo charcoal photocatalysts in an aqueous solutionof 2,4-dichlorophenol(DCP)was tested alongwith catalytic activity of the regenerated photocatalyst using different initial concentrations of 2,4-DCP and pH. A nanometer-sized TiO2 photocatalyst was modified for bamboo charcoal with tetrabutyl titanate using the sol-gel-dip method and then described with X-ray diffraction(XRD). Results showed thatin 75 min at an initial concentration 120 mgL- 1 and pH10, the rate of photocatalysis degradation for 2,4-DCPwas 96.4%.Thiswas more thanwith TiO2and bamboo charcoal that had a regenerated photocatalyst activity rate of 96.3%. Meanwhile, when pH was 6, the rate of photocatalysis degradation of 2,4-DCPwas only 61.7%.[Ch, 3 fig. 1 tab. 14 ref.]
