Cetyltrimethylammonium bromide(CTAB)and polyethylene glycol(PEG),as well as CTAB and polyethylene glycol octylphenylmethylene(OP)were used as dual templating agents to induce the synthesis of MoVTeNbO composite metal oxide catalysts with mesoporous structure.The synthesized catalysts were applied to the selective oxidation of propylene to acrylic acid.The results show that when using the dual template agents CTAB and PEG,MoVTeNbO composite metal oxide can be induced to form a mesoporous structure with uniform pore size distribution concentrated at 4~10 nm and pore volume of 0.058 cm³/g under n（Mo）∶n（V）∶n（Te）∶n（Nb）∶n（PEG）∶n（CTAB）=1∶0.34∶0.22∶0.13∶0.056∶0.047.When CTAB and OP were used as dual template agents with different concentrations,mesoporous MoVTeNbO catalysts could also be induced to synthesize,in which, when n（Mo）∶n（V）∶n（Te）∶n（Nb）∶n（OP）∶n（CTAB）=1∶0.34∶0.22∶0.13∶0.011∶0.044,the pore size distribution was concentrated in the range of 7-14 nm with pore capacity of 0.132 cm3/g.The synthesized catalyst showed good catalytic activity in the oxidation of propylene to acrylic acid,the selectivity of acrylic acid could reach up to 82%.Compared with the catalyst prepared without CTAB and OP,the selectivity of acrylic acid was increased by at least 22.78%.
