Carbon foams (CFs) were prepared by using waste polyurethane foams (PUFs) as hard templates and phenolic resin as a carbon source. The obtained CFs were treated to be hydrophilic with plenty of carboxyle group by a wet oxidization method. Mesoporous TiO2 films were then facilely deposited on hydrophilic carbon foams (hydro-CFs) because the hydrophilic carbon surface facilitates the formation of uniform coating layer. The macroporous hydro-CFs act as not only the supports of TiO2 films but also the adsorbent for enriching the VOCs at the interface of hydro-CF and mesoTiO(2) films. The UV-vis and visible light irradiation photocatalytic oxidation of acetone and toluene was evaluated on mesoTiO(2)/hydro-CF, which is higher than that of pure mesoTiO(2) and mesoTiO(2)/CF. The mesoTiO(2)/hydro-CF even showed visible light activity for acetone degradation due to the plausible carbon doping due to the strong interaction between the TiO2 precursor and the hydro-CFs.
