The catalytic activity of M/Ga–H-ZSM-5 metal zeolites in the selective reduction of nitrous oxide by methane was found to depend on the combined action of free acid sites of zeolite and redox sites of d-metal oxide nanoparticles. A relationship was

Bimetallic AuPd catalysts were prepared by deposition of bimetallic aqueous sols formed in different ways: (i) co-reduction of the precursor Au and Pd ions by Na-citrate/tannic acid mixture, (ii) reduction of Au(III) ions onto preformed Pd sol, and (
