AI Technical Summary
Existing denitrification catalysts suffer from high costs due to high precious metal loading, low utilization of active sites, and poor catalytic activity at low temperatures.
Using materials such as magnesium oxide, titanium oxide, or cerium oxide as carriers, an amorphous coating layer is formed on the surface of an active metal through hydrothermal treatment. This constructs active sites at the active metal/oxide reverse interface, alters the adsorption configuration of NO molecules, and promotes efficient coupling between H2 and NO at the active sites at the interface.
It significantly improves the low-temperature catalytic activity and active site utilization of the denitration catalyst, reduces the loading of precious metals, and lowers the catalyst cost.
