Perfect catalytic oxidation of formaldehyde over a Pt/TiO2 catalyst at room temperature

A 1 wt% Pt/TiO2 catalyst was prepared and tested for the catalytic oxidation of formaldehyde (HCHO) at room temperature. The results of activity tests showed that HCHO can be completely oxidized over the Pt/TiO2 catalyst in the space velocity of GHSV = 50,000 h−1 at room temperature. A mass balance study proved that HCHO selectively oxidized into CO2 and H2O over Pt/TiO2 at room temperature. No by-products were found in the effluent gases. The XRD patterns indicated that platinum is in a very high dispersion degree on TiO2.
