Ammonium metatungstate (AMT) is a significant tungsten compound, highly valued for its catalytic properties in industrial applications. For instance, in the production of denitration catalysts, AMT-based catalysts typically use titanium dioxide as a carrier. Through specialized preparation processes, AMT is loaded onto the carrier, forming a catalyst with high activity and stability, used to adsorb pollutants like sulfur and nitrogen oxides emitted from coal-fired power plants. In petroleum refining, AMT serves as a catalyst to promote cracking reactions, hydrodesulfurization, and hydrodenitrogenation reactions.
