Abstract
An exhaust system for an internal combustion engine comprises a catalyst chamber, a silver catalyst positioned within the catalyst chamber and means to supply a quantity of hydrogen to the catalyst chamber, wherein the silver catalyst is disposed in one of the following arrangements: (i) the silver catalyst is deposited on a soot filter or as a component of a Catalytic Soot Filter; (ii) the silver catalyst is disposed upstream of a soot filter; and/or (iii) the silver catalyst is disposed upstream of a selective catalytic reduction catalyst, and wherein NO2 is generated by contacting the silver catalyst with hydrogen. A method of generating NO2 comprising the step of passing NO in the presence of a gaseous oxidising agent over a silver catalyst in the presence of a quantity of hydrogen is also disclosed. In both the exhaust system and the method of generating NO2 the catalyst may be Ag/Al2O3.
