New ceramic materials based on silicon nitride and obtained by self-propagating high-temperature (SPHT) synthesis were investigated. The Si3N4 materials modified with Zr and Al compounds were used as supports for silver-containing catalysts of selective oxidation of ethyleneglycol into glyoxal. The procedure for the synthesis of supported silver-containing catalysts affected the structural and morphological states of the active component before and after the catalytic reaction.
