Abstract
- A new preparation process of the vanadium catalyst with nano-V2O5 particles was introduced in this paper. The inorganic sol-gel method is used to prepare the sols and gels with p nano-V2O5 particles. The morphology, size and distribution of the nano-V2O5 particles in the sols-gels and vanadium catalyst had been studied by TEM, SEM, XRD and DSC. The results show that with the w/v (the ratio of water and vanadium) declining, the morphology of the nano-V2O5 particles varies from needle to near-ball then to sphere; the better process parameter to prepare the sols and gels with nano-V2O5 particles is 800~860°C×10~15min; the sols and gels and catalyst with 30~60nm V2O5 particles had been obtained by this process.
