Abstract More than half of the solar spectrum is near infrared (NIR) light. However, the report concerning the photocatalytic reaction using NIR light is rare. In this work, a full-spectrum-driven W₁₈O₄₉/g-C₃N₄ heterojunction catalyst was prepared and the photocatalytic RhB degradation ability was investigated. X-ray diffraction, N₂ adsorption, UV-Vis-NIR spectroscopy, scanning electron microscope, transmission electron microscope, photoluminescence, X-ray photoelectron spectroscope and electrochemical impedance spectra were used to characterize the prepared catalysts. The result indicates that as-prepared W₁₈O₄₉/g-C₃N₄ heterojunction catalysts display strong light absorption in the region of 250—1 800 nm. The reaction rate constant for W₁₈O₄₉/g-C₃N₄ heterojunction catalyst arrives 0.015 9 min^-1, which is 5.3 times and 11.4 times higher than that of neat g-C₃N₄ and W₁₈O₄₉, as well as excellent catalytic stability. In addition, the mechanism of degradation of RhB by W₁₈O₄₉/g-C₃N₄ heterojunction catalyst was investigated.

Key words： g-C₃N₄ W₁₈O₄₉ full-spectrum heterojunction photodegradation
