英文摘要	g-C3N4@CdS nanocomposites with different mass ratios were successfully fabricated by the precipitation method. Different ratios were investigated for their influence on the microstructure, photoelectrochemical, and photocatalytic properties of the as-prepared samples. The experimental results show that g-C3N4@CdS nanocomposites are hexagonal structures with good crystallization, and g-C3N4 wraps one-dimensional CdS nanorods. g-C3N4@CdS nanocomposites exhibit excellent visible-light absorption. The PL spectra, transient photocurrent response, and EIS measurements of g-C3N4@CdS composites indicate that heterojunctions accelerate the separation and migration of photo-generated electron-hole pairs and inhibit the recombination of photo-generated carriers. Under simulated sunlight irradiation, the g-C3N4@CdS photocatalyst accelerates the redox reaction and improves photocatalytic efficiency to degrade MO, compared to pure photocatalysts. g-C3N4@ CdS photocatalysts exhibit good degradation efficiency and excellent recyclability. In addition, O-center dot(2)- and( center dot)OH play a key role in the photocatalytic degradation process.
