A series of TeMox (x = 3–6) mixed oxides were prepared and investigated for the selective oxidation of isobutane and isobutene. Both the characterization results and the catalytic properties of the samples are quite different, depending on the composition of the calcined samples. Among them, TeMo3 catalyst showed the best total selectivity to methacrolein and methacrylic acid (as high as 46%), and their yield reached 10.1% at 400°C in the selective oxidation of isobutane. How ever, TeMo4 catalyst showed the best catalytic performance in the selective oxidation of isobutene, in which 73% selectivity to methacrolein and 9% selectivity to methacrylic acid can be obtained at 77.5% isobutene conversion at 440 graduate C.
