摘要：

A novel hierarchical porous carbon aerogel (HPCA) was fabricated and its nanostructure was investigated by SEM and N2 adsorption. The methylene blue (MB) adsorption properties of the HPCA in water were studied. It is found that the HPCA has a hierarchical micro-, meso- and macropore structure. Its BET and micropore surface areas are 512 and 359 m2·g-1, respectively. The MB adsorption capacity increases with adsorption time, speed of stirring, temperature and pH value, and the MB removal efficiency can reach 99.8% under optimized conditions. The adsorption kinetics can be well described by a pseudo-second-order equation and the adsorption is controlled by liquid film diffusion in the initial stages and intraparticle diffusion later. © 2015, Editorial Board of New Carbon Materials.
