Graphitic carbon nitride (g-C3N4) was synthesized by heating melamine and was then treated with sodium hydroxide solution under a hydrothermal condition to obtain g-C3N4 with a large specific surface area (HSSA). HSSA shows higher photocatalytic activity for decomposition of acetaldehyde than that of original g-C3N4. HSSA was modified with RuO2 as a co-catalyst by the impregnation method. HSSA loaded with 0.05 wt% RuO2 shows the highest photocatalytic activity for acetaldehyde decomposition under visible light (λ = 455 nm).
