The present Study involves synthesis and characterization of M(IV) phosphates and tungstates which are inorganic cation exchangers of the class of tetravalent metal acid (tma) salts possessing structural hydroxyl groups, the H of the structural -OH being the cation exchange sites, which indicates good potential for application as supports in heterogenized homogeneous catalysis. Ru(III) has been exchanged onto these materials by an ion exchange technique and catalytic activity investigated for oxidation of benzyl alcohol and styrene. Further, Ru(III) has been reduced to Ru(0) and catalytic activity has been explored for hydrogenation of 1-octene, nitro benzene, and cyclohexanone.
