Abstract
Novel Ag3PO4/CNFs/silica-fiber composite photocatalyst was successfully synthesized via a facile combined chemical vapor deposition (CVD) technique and hydrothermal process. The as-prepared Ag3PO4/CNFs/silica-fiber was characterized by X-Ray diffraction, field emission scanning electron microscopy, ultraviolet–visible diffuse reflectance spectroscopy, and photoluminescence spectroscopy. The photocatalytic activity of Ag3PO4/CNFs/silica-fiber was evaluated by the degradation of rhodamine B (RhB) under visible-light irradiation. Note that the existence of unique featured CNFs not only has good adsorption ability for RhB molecules, but also benefits to the effective separation of photogenerated electron–hole pairs and thus improves the photocatalytic performance of the catalyst. Specially, the as-prepared Ag3PO4/CNFs/silica-fiber photocatalyst can easily reduce the cost for the practical application of Ag3PO4 photocatalyst. The new synthetic procedure is simple and could be applicable to a large number of efficient and inexpensive visible-light-driven photocatalytic materials.
