摘要： A preparation method for a silver (Ag) and graphitic carbon nitride (g-C3N4) co-modified zinc oxide (ZnO) nanocomposite material using a polymer network gel method includes: dispersing zinc oxide, bulk graphitic carbon nitride, and a soluble silver salt in water to obtain a first solution; adding glucose, a complexing agent, a polymer monomer, and a cross-linking agent into the first solution to obtain a second solution; performing a heating reaction on the second solution to obtain a three-dimensional network wet gel; drying the three-dimensional network wet gel to obtain a dry gel, and calcining the dry gel to obtain the Ag and g-C3N4 co-modified ZnO nanocomposite material. The preparation method has advantages of low cost, short period and simple steps; and the prepared nanocomposite material can be simultaneously applied to photocatalytic degradation of organic dye pollutants and photoexcitation detection of nitrogen dioxide gas at room temperature.
