Abstract
A method for oxidizing a carbonaceous material, the method comprising contacting the carbonaceous material with an effective amount of a catalytic material of formula AxMyWOz, and initiating the oxidization of the carbonaceous material at a first temperature lower than a second temperature at which the carbonaceous material is initiated to oxidize without a catalyst, wherein A is at least one of cesium and potassium, M is different from A and is at least one of cesium, potassium, magnesium, calcium, strontium, barium, iron, cobalt, nickel, ruthenium, rhodium, palladium, silver, osmium, iridium, platinum, gold, yttrium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, and bismuth, 0≦x≦1, 0≦y≦1, 2.2≦z≦3, when x=0, y>0, and when y=0, x>0.
