Gas-solid heterogeneous photocatalytic oxidation (PCO) of heptane and toluene over UV-illuminated pure titania, titania-silica mixed oxides and sulfated titania was investigated at room temperature in a batch reactor. By comparing the photocatalytic activities of the different catalysts, we draw the
Doping sulfated zirconia with silica increases the acidity of the sulfated zirconia. This modified catalyst was used for liquid-phase dehydration of methanol at 413-453 K as a model reaction. Methanol is sequentially dehydrated to dimethyl ether and ethylene over both sulfated zirconia and silica-do
