Abstract

In this work, g-C3N4/TiO2 nanocatalysts were prepared by high-voltage electrospinning and hydrothermal methods. The surface of the pure TiO2 nanomaterial was treated by acidification before it was combined with g-C3N4.Various characterization methods were used to characterize the prepared photocatalyst. RhB (20 mg/L) was degraded as a target-degradable pollutant, the degradation efficiency of the nanocatalyst was measured under UV–Visible light. The results show that the degradation efficiency of the g-C3N4/TiO2 nanocomposite material that has undergone pre-acidification treatment is much higher than that of the untreated catalyst.
