Abstract
Abstract A one step simultaneous synthesis of V 2 O 5 /TiO 2 nanocomposite particles was carried out using a modified-chemical vapor deposition (CVD) process employing two metal-organic precursors. The flow rate of the vanadium precursor was varied from 0 to 3 L/min with the flow rate of the TTIP precursor kept constant. The pure TiO 2 and prepared V 2 O 5 /TiO 2 nanocomposite particles were examined by BET, XRD, XPS, TEM and SEM-EDS. The results showed that both the vanadium concentration and particle size increased with increasing flow rate of the vanadium precursor, whereas the specific surface area decreased. XPS confirmed that the nanocomposite particles consisted of Ti, V and O. The V 2 O 5 /TiO 2 nanocomposite particles had a mean size of 20–40 nm. TEM showed that the flow rate had a significant effect on the particle size. The V 2 O 5 /TiO 2 nanocomposite particles are expected to have a wide range of applications in many fields, such as catalysts, photoelectron materials and sensors.
