The vertices are Al or Si and an O is assumed to be bonded between the vertices. In the present work, ZSM-5 was prepared by using Colloidal Silica and sodium aluminate as silicon and aluminium sources respectively. Since, ZSM-5 acts as catalyst even at prolonged high temperature, the ZSM-5 is used for the Selective Catalytic Reduction of (SCR) of NOx in the exhaust pipe of diesel engine. A thin film of ZSM-5 was developed on the metal sheet by hydrothermal method forms a Selective Catalytic Reduction (SCR) catalyst of plate type of structure. The characterization of SCR catalyst is carried by subjecting to X-ray diffraction, BET test, erosion test. The surface area per unit weight for uncalcined sample was 40.635 m2/g. The X-ray diffraction shows that the topology of the prepared silicate-1. Keywords: ZSM-5;SCR catalyst;COMSOL multiphysics;X-ray diffraction
