The MCMB were treated by the surface modification procedures and marked the product as DMCMB. Then the preparation of nanoparticles/DMCMB in-situ composites were finished by hydrothermal synthesis. The MCMB without surface treatment is used as a blank test by the same process.The samples were characterized by X-ray diffraction, FTIR spectroscopic, specific surface area test and scanning electron microscope. It was found that the DMCMB were coated by a large number of granular metallic oxide with an average di- ameter of 50~80 nm. While there was almost nothing coating over the MCM]3 without an...
