As a kind of porous clay mineral material, diatomite has some advantages like rich reserves, low cost, and high specific surface area, which can be used as an excellent carrier of phase change material (PCM). Recent work on high-efficiency diatomite PCM is to improve its latent heat and thermal conductivity. This review represented recent research progress on the specific surface area modification and thermal conductivity enhancement modification of diatomite PCM and analyzed the thermal properties of diatomite with different types and contents of PCMs. In addition, some problems of diatomite PCM application were described, and the future research directions were prospected.
