The pre-acidizing corrosion on the surface of TiO2 enhanced the photocatalytic activity of g-C3N4/TiO2

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.

Automated summary

g-C3N4/TiO2 nanocatalysts were prepared using high-voltage electrospinning and hydrothermal methods, with the surface of TiO2 nanomaterial treated by acidification. Characterization methods were used to analyze the prepared photocatalyst, showing higher degradation efficiency for the nanocomposite material with pre-acidification treatment compared to the untreated catalyst.
