摘要	The inadequate utilization of low-grade energy from industrial waste heat and solar energy calls for an efficient thermochemical heat storage material. The fabrication of a low-cost but highly efficient composite comprising highly porous biochar and LiOH center dot H2O nanoparticles for heat storage applications is reported. The biochar is prepared by the KOH-assisted pyrolysis of dead banyan leaves, and its microstructure and surface properties can be finely tuned by varying the KOH-to-biomass ratio. Such biochar can be mediated to possess a large specific surface area and total pore volume reaching as high as 1255.03 m(2) g(-1) and 3.65 cm(3) g(-1), respectively, superior to most previously reported biochar/biocarbon derived from different kinds of waste biomass. Besides, adequate functional groups and a hierarchical porous structure consisting of micropores and mesopores are demonstrated in the prepared biochar. The subsequent hydrothermal reaction with a short duration yields a biochar-LiOH center dot H2O composite, where LiOH center dot H2O can be homogeneously immobilized with a nanoscale size within the porous biochar matrix. Thus, an enormous biochar/LiOH center dot H2O nanoparticles interface can be obtained, resulting in fast hydration reactions with water molecules. Consequently, a significant heat storage density of as high as 3089.6 kJ kg(-1) is achieved within only 10 min, outstripping some recently reported thermochemical heat storage systems.
