Abstract

The influence of hydrothermal, microwave, and mechanochemical treatments on porous structure of amorphous zirconium phosphate has been studied. Specific surface area and porosity of modified samples have been investigated by the help of nitrogen adsorption-desorption and adsorption of water, methanol, and benzene vapours. It has been found that hydrothermal and especially microwave treatments of wet gels allow us to prepare meso-macroporous zirconium phosphate samples which have high specific surface area, total pore volume, and size of pores. Mechanochemical treatments of gels results in formation of uniform mesoporous structure. Surface fractal dimension of zirconium phosphate samples modified via different methods has been calculated.
