摘要Mesoporous silica−cellulose hybrid composites were prepared by surface sol−gel coating process on nature cellulose substance. The template CTAB (hexadecyl trimethyl ammonium Bromide) in the silica film can be removed by extraction to obtain high specific surface area (80.7 m2 g−1), which is 2 orders of magnitude higher than that of raw cellulose. In the following, the enzyme-mimetic catalyst and chromogenic agent were introduced onto the hybrid system. Just as the peroxidase, the resultant hybrid material exhibits extraordinary sensitivity for the H2O2 and shows an immediate and obvious color change. The detection limit is about 1 μmol L−1 by the naked eye.; Mesoporous silica-cellulose hybrid composites were prepared by surface sol-gel coating process on nature cellulose substance.
