摘要: Solar-light-driven carbon-based photocatalysts have been widely used for CO2 conversion reaction. In this work, silver iodide (AgI)-decorated 2D structure graphitic carbon nitride (GCN) composite was prepared using nitrogen-rich melamine precursor and the characterization results reveal that mixture of hexagonal wurtzite cubic phases β,γ-AgI are incorporated on GCN surface. Consequently, photoconversion over AgI/GCN tested under visible light irradiation in triethanolamine medium. The main products from were methane, acetone ethanol. Besides, effects metal AgI loading (0.5–1.5%), amount photocatalyst (1–4 g/L) time evaluated. Furthermore, charge separation mechanism associated with also discussed.
