Increasing the Mo/V ratio accelerates the dispersion of V–O–V on TiO2 support.
Improving the loading of active species with constant Mo/V ratio went against catalytic property.
The V0.9–Mo7.2/Ti/CC catalyst exhibits the best catalytic performance in 350–450 °C.
The V–Mo/Ti/CC catalysts exhibit a desirable mechanical strength and washcoating stability.
