The adsorption kinetics of cellulase and xylanase immobilized on magnetically separable, hierarchically ordered mesocellular mesoporous silica (M‐HMMS) was investigated. The adsorption of cellulase on M‐HMMS followed pseudo‐second‐order kinetics while the xylanase adsorption followed the Avrami model. Intraparticle and film diffusion also affected this process. These results enable in‐depth knowledge of the cellulase and xylanase adsorption mechanisms on M‐HMMS for better future applications by improving the stability of the immobilization.
