✦ Synopsis

The formation of metallic lead phase normally observed in lead oxide-promoted Li/MgO catalysts during the oxidative methylation of toluene with methane was overcome by the substitution of lead oxide precursom, such as Pb(NOa)2 with Pb.~(PO4)~ in the catalyst preparation step. The PbO phase formed in the initial calcination of lead phosphate-promoted Li/MgO catalyst was stabilized by the cooperative effect of Li, P and 0 components during the catalytic reaction.
