Resum
Aluminum was incorporated into SBA-15 supports at molar ratios Si/Al = 10 and 2 by the pH-adjusting method. The calcined mesoporous Al-SBA-15 supports, as well as the Al-free SBA-15 support, were impregnated with ammonium paratungstate ((NH4)(10)center dot[H2W12O42]center dot 4H(2)O) aqueous solution. Tungsten carbide (W2C) was synthesized by temperature programmed carburization (TPC) from the. WO3 supported on AI-SBA-15 and SBA-15 in a flow of CH4/H-2. These resultant materials were characteriz...
