Procedure

To 40 ml of water is added 0.387 gram of vanadium pentoxide, 0.851 gram of oxalic acid and 1.937 grams of formamide at room temperature with stirring to form vanadium oxalate, and this solution was then mixed with 20.0 grams of the titanium dioxide anatase powder (which were first dispersed in 20 ml of water). The resulting mixture was heated with stirring at 65° C. to evaporate the majority of the water, followed by drying in an oven (101kPa) at 110° C. for 16 hours. The resulting solid was then calcined in a flowing oxygen gas stream at 450° C. for 2 hours, followed by crushing and screening to form -20+40 mesh particle size. The catalyst formed by the above impregnation procedure was determined by calculation (based on the vanadium salt and the weight of the titanium dioxide particles) to contain 1.9 wt. % V2O5 on the TiO2.
