Abstract
This thesis is concerned with the synthesis and characterisation of CuAPO-5, CuSAPO-5 and also copper ion-exchanged SAPO-5, SAPO-11 and ZSM-5. The ability of these materials to catalyse the selective reduction of NOx using propene as the reducing agent (SCR-HC) in an oxygen rich environment has been investigated. NOx, a term representing the nitrogen oxides, is part of the waste gases emitted from combustion processes in both stationary and mobile sources. NOx is a potent pollutant because it reacts with sunlight in photochemical processes to produce smog and acid rain making it a serious environmental challenge globally.
