One of the goals of this project was to utilize the hydrothermal method in preparation of α-MoO3 nano-belts as bluish power at 180 o C for 5h.This nanomaterial was incorporated with rutile-TiO2 to produce a nanocomposite photocatalyst by a direct ultrasonic method in a ratio of 0.25(α-MoO3): 9.75(TiO2) as w/w ratio.The characterized of samples found by X-ray diffraction(XRD), scan electron microsc...
