Thermochemical heat storage is a practical approach for overcoming the challenge in solar energy applications. Herein, we synthesize a novel MgCl₂/MXene (Ti₃C₂T_x) composite sorbent by impregnation method for low-temperature thermochemical heat storage application. Various techniques, including Thermogravimetric coupled with Differential Scanning Calorimetric (TG-DSC), X-Ray, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) were applied to characterize the mechanical and thermal properties of MgCl₂/MXene composites. The result showed that Ti₃C₂T_x possess a larger specific surface area and the hydrophilic groups allow maximum MgCl₂ adsorption without structural distortion. The TG-DSC studies showed that the fourth DSC peak of MgCl₂ (181.33 °C) is shifted in composites MX/Mg 15 % (159.63 °C) and MX/Mg 10 %, (141.67 °C) toward lower dehydration …
