Ni-doped MF(melamine-formaldehyde) aerogels are prepared through impregnation-reduction with the hydrazinium hydroxide(80%, AR) as the reducing agent after MF aerogels being activated by PdCl2. Both the Scanning Electron Microscope(SEM) and the Transmission Electron Microscope (TEM) images demonstrate that there are a great deal of Ni particles with a size of 100nm existing in the framework of MF aerogels. Meanwhile, a small part of clusters is observed in the SEM and TEM images. The nitrogen adsorption-desorption data show that the specific surface area, total pore volume and micropore volume of MF aerogels all decrease after Ni doping. Moreover, a small amount of macropore is produced by large size Ni particle clusters, further confirming that the nanochannels of MF aerogels are filled with Ni.
