| titleOfInvention | Full-spectrum photo-thermal conversion heat storage material and preparation method thereof |
| abstract | The invention discloses a full-spectrum photothermal conversion heat storage material and a preparation method thereof, wherein the heat storage material consists of a heat storage substance capable of generating thermochemical reaction and a spectrum absorption enhancing substance with a full-spectrum solar photothermal conversion function, and the preparation method of the material comprises the following steps: (1) preparing a precursor solution, wherein the precursor solution is formed by mixing a solution a and a solution b, a solute in the solution a is a substance capable of generating a thermochemical reaction after the preparation step is finished, and a solute in the solution b is a substance capable of enhancing spectral absorption after the preparation step is finished; (2) evaporating water in the precursor solution in a water bath until wet gel is obtained; (3) aging; (4) drying to obtain fluffy solid; (5) crushing and grinding the fluffy solid into particles; (6) the resulting particles were calcined and annealed to room temperature. The material can realize photo-thermal conversion within the wavelength range of 280nm-2000nm with concentrated solar energy, and is combined with thermochemical heat storage, so that a heat collection and heat storage system is simplified. |
