FIELD: chemistry.
SUBSTANCE: invention relates to method of obtaining catalyst by covering cellular bodies with crystalline layer of metal with catalytic properties. Before application of crystalline layer coating on surfaces of cellular bodies said surfaces are preliminarily covered with precious metal powder, which has particles size <10 mcm. Cellular catalyst has twice covered surface with crystalline metal layer applied on surface. Between surface of cellular body (4) and crystalline metal layer (3) there is an intermediate layer (2) formed of burnt precious metal powder. Catalyst is applied for purification of spent gases and catalyst combustion. Method for application in flameless catalytic condensation boilers, further catalytic purification in thermal systems of spent air purification and as coating for membranes of fuel elements is also described.
EFFECT: preliminary covering with stainless steel coating results in obtaining product for long-term application, lower sensitivity, wider range of application temperatures and longer service term.
