Titania-loaded coal char as catalyst in oxidation of styrene with aqueous hydrogen peroxide
Titania-loaded coal char catalyst was successfully prepared. The preparation steps involved pyrolysis of low rank coal at different temperatures and durations, sulfonation, impregnation of titanium(IV) isopropoxide, and then heating at 110°C. It is found that the coal chars' surfaces were rough...
