Experimental Study of V_2O_5-WO_3 DeNO_x Catalystsover Commercial Anatase TiO_2;

An experiment was performed on the vehicle diesel engine to study the DeNOx performance of V2O5-WO3/TiO2 catalyst based on SCR technology,and the comparison between the test results and foreign commercial catalyst was made.

Physical-chemical characteristics of the self-developed catalyst V_2O_5-WO_3-MoO_3/TiO_2 have been determined by static N_2 adsorption and XRD,its activity evaluated with a fixed bed continuous reactor and factors that influence the catalyst's activity analyzed.

In order to enhance the performance of inert anodes of Ag/NiFe_2O_4 cermet,the inert anode of nickel ferrite based cermet with 15% excess NiO was prepared by the powder metallurgy method using NiO,Fe_2O_3,Ag and a little V_2O_5 as raw materials.

Carbon was chosen as the reductant to prepare VO_2 from V_2O_5.

Nano structured tungsten oxide films have been prepared using a sol-gel process with the starting tungsten powders together with the spin coating method in this paper.

Nano powder tungsten oxide is prepared by using a sol-gel process with oxalic acid and benzoic acid as coagulator.
