文摘

A facile and low-cost microwave method was used to prepare C and N co-doped TiO₂ in just 8 min. The prepared samples were thoroughly characterized and were found to have favourable features such as surface adsorption of pollutants and photocatalysis. The rapid decomposition of CH₅N₃HCl under microwave irradiation led to mesopores and surface roughness in the as-prepared particles, resulting in large surface adsorption of pollutant and good photodegradation. The best sample is the one with the ratio of TiO₂/CH₂N₃HCl at 3:1, which adsorbed 86.3 % of a methylene orange (MO) solution (20 mg L−1) in 10 min.
