Abstract

A porous calcium silicate hydrate, a preparation method thereof and an adsorbent are provided. The preparation method of the porous calcium silicate hydrate includes: leaching fly ash with an alkali agent to obtain a silicate leaching solution; adding the silicate leaching solution dropwise to a calcium hydroxide suspension at a constant rate, and conducting stirring and a heating reaction to obtain a calcium silicate hydrate gel; and mixing the calcium silicate hydrate gel with an organic alcohol solvent, conducting azeotropic distillation, and then conducting separation, drying and calcination to obtain the porous calcium silicate hydrate.
