摘要: Abstract 3C-SiC nanowires with hierarchical structure were synthesized by sol–gel carbothermal reduction method. The photocatalytic property of SiC was investigated. exhibited an enhanced activity accelerating the degradation methylene blue solution under visible light irradiation. Methylene degraded efficiently after 5 h irradiation over photocatalyst. affected initial concentration solution. Silicon dioxide layer observed on surface catalytic process. positive effect SiO 2 oxygen vacancies and nanostructures high decolorization efficiency discussed. detailed redox processes also explained.
