Facile immobilization of LnVO4 (Ln = Ce, Nd, Gd) on silica fiber via a combined alcohol-thermal and carbon nanofibers template route

• A facile method of LnVO4 (Ln = Ce, Nd, Gd) immobilization was developed.
• A combined alcohol-thermal with carbon nanofiber template route was used.
• The obtained materials work as efficient UV light driven photocatalysts.
• This method might be applicable to other novel material fabrications.

A facile immobilization method of LnVO4 (Ln = Ce, Nd, Gd) was designed for the first time, via a combined alcohol-thermal and carbon nanofibers (CNFs) template route. The physicochemical properties of the prepared samples were characterized in detail and their photocatalytic activities were evaluated via UV light photocatalytic degradation of methylene blue (MB). The results show that the photocatalytic degradation of MB was pretty effective for the prepared LnVO4 (Ln = Ce, Nd, Gd) samples, and the photocatalytic degradation efficiencies follow the order: GdVO4 > CeVO4 > NdVO4. It is expected that such unique immobilized LnVO4 materials would possess many potential applications in photocatalysis.
