摘要: Abstract Multi-walled carbon nanotubes (MWNTs) were used as a catalyst for catalytic wet air oxidation (CWAO) of phenol in batch reactor. SEM, TEM and FT-IR technique applied to investigate the microstructure surface functional group MWNTs. When carboxylic groups (–COOH) are grafted onto MWNTs, functionalized MWNTs exhibit good activity CWAO phenol. At reaction temperature 160 °C, oxygen pressure 2.0 MPa concentration 1000 mg/L, 100% 76% TOC removed after 120 min reaction.
