Abstract

Diatomite is a kind of non-metallic mineral formed by diatom plants through a long period of sedimentation and diagenesis.Diatomite can be used as a good adsorption carrier material and has been widely concerned because of its rich micropores,high temperature resistance,corrosion resistance,low price and abundant resources.The structural characteristics of diatomite was introduced,and the common modification methods of diatomite were summarized.The research status on the types and preparation methods of diatomite-based shape-stabilized phase change materials (SPCMs) was reviewed,and the application progress of diatomite-based SPCMs in the field of architecture was summarized.On this basis,in order to provide some references for the large-scale promotion of diatomite-based SPCMs,the problems existing in the current research stage were analyzed,and the key work of future research was proposed.
