Abstract:

Currently, with the scarcity of primary energy, the significance of energy utilization efficiency has been gained much attention. Phase change thermal storage can effectively enhance energy utilization efficiency, people have started to combine phase change materials with other substances to further increase their application scope. Nano-titanium dioxide has been widely studied for phase change thermal storage thanks to its low cost, non-toxic, high electrical conductivity, high chemical stability, and high thermal stability, etc. The research progress of nano-titanium dioxide in phase change energy storage field is reviewed, which is mainly divided into the following two parts in terms of function of nano-titanium dioxide in composite phase change materials: (1) the current situation of research on the application of nano-titanium dioxide in shape-stabilized phase change materials; (2) the research progress of nano-titanium dioxide in other functional phase change materials. The aim of this paper is to provide a theoretical basis and reference for further applications of nano-titanium dioxide in phase change energy storage filed.

Key words: titanium dioxide, nanomaterials, phase change, renewable energy
