Abstract

The invention relates to a microwave-assisted preparation method for spherical transition metal and zirconium diphosphonate in one step. The microwave-assisted preparation method comprises the following steps: preparing a water-soluble transition metal salt, a water-soluble zirconium, a water-soluble phosphoric acid source and water-soluble fluoride into an aqueous solution respectively, and mixing; then, performing microwave-assisted heating, centrifuging, washing and drying to obtain transition metal and zirconium diphosphonate. The microwave-assisted preparation method is simple, convenient to operate, less in time consumption and high in efficiency; the prepared transition metal and zirconium diphosphonate are regular in morphology, and can be used as a catalyst, an ion exchange material, an antibacterial material and the like without being roasted at a high temperature.

Description

technical field

[0001] The invention belongs to the field of preparation methods of bisphosphonates, in particular to a method for preparing spherical transition metal and zirconium bisphosphates in one step with microwave assistance. Background technique

[0002] Zirconium phosphate α-ZrP(α-Zr(HPO 4 ) 2 ·H 2 O) is a typical cationic layered structure compound. Zirconium phosphate and its derivatives have high thermal stability, chemical stability and strong acid and alkali resistance, as well as zeolite-like shape-selective adsorption and Catalytic performance, so it is widely used in intercalation chemistry, catalysis, adsorption, membrane, fuel cell, biology, photochemistry and other fields.

[0003] Transition metal and zirconium bisphosphate ZrM(PO 4 ) 2 As a catalyst, it can be used to catalyze isomerization of alkanes, selective oxidation of methane to generate synthetic gas, oxidation of propane to dehydrogenation, selective oxidation of propylene to alcohols to...
