Two-dimensional photocatalyst with highly efficient and stable visible light photocatalytic activity

Abstract

Hex ammonium molybdate (AHM), ammonium nitrate (NH₄NO₃), and glycine were used as the precursors in a microwave-assisted solution combustion synthesis (WSCS) process to create foam-like MoO₂ nanoparticles. Methodically investigated was the effect of the glycine/NH₄NO₃ ratio (=0.25, 0.50, 0.75, 1.0 and 1.25) on the finished goods. The findings indicate that the final morphologies and phases of the products are virtually influenced by the value of Φ. MoO₂ nanoparticles measuring 20 to 30 nm can be successfully composited under the condition of Φ=0.50 to produce a foam-like result. The photocatalytic activity of foam-like MoO₂ nanoparticles was tested with several pollutants. The results show that foam-like MoO₂ nanoparticles have good degradability and stability. The photocatalytic mechanism and fabrication mechanism of foam-like MoO₂ has been presented in detail. Using foam-like MoO₂-based photocatalyst materials for energy transfer and environment protection is supported by this research.
