The effect of Gd dopant on phase, morphologies and photocatalytic activities of MoO3nanobelts was investigated. The X-ray diffraction (XRD) and transmission electron microscopy (TEM) results show that pure and Gd-doped products are orthorhombic MoO3and Gd-doped MoO3nanobelts with their growth along the [001] direction. Photocatalysis of 0-3 mol% Gd-doped MoO3nanobelts were monitored through degradation of methylene blue (MB) solutions under visible radiation. The Gd-doped MoO3nanobelts show better photocatalytic performance than pure MoO3nanobelts. The 3 mol% Gd-doped MoO3photocatalyst exhibits the highest visible-light-driven activity for photodegradation of MB solution of 99% within 60 min.
