Preparation and Photocatalytic Properties of g-C3N4/TiO2/BiVO4

摘要

Over the last few decades, the semiconductor-based photocatalysis has emerged as an environmentally benign technology for wastewater treatment due to its destructive ability towards a wide range of inorganic and organic pollutants. TiO2 is by far the most commonly being researched photocatalytic material owing to its many advantages for photocatalytic applications, e.g. high redox potentials, long-term thermodynamic stability, costeffective and non-toxicity. Whereas the bare TiO2 suffers from several disadvantages including the limit to ultraviolet (UV) light absorption due to its wide band gap, as well as low quantum efficiency resulting from the rapid recombination of photogenerated electron¨Chole pairs. To overcome these drawbacks and enhance the photocatalytic activity of TiO2, we constructed and prepared a ternary catalyst, i.e., mpg-C3N4/TiO2/BiVO4.
