Photothermal conversion mineral material as well as preparation method and application thereof
The invention provides a photothermal conversion mineral material as well as a preparation method and application thereof. The mineral material is obtained by performing in-situ synthesis on mesoporous silica in macropores of expanded perlite and then performing carbon coating on the surface of the mesoporous silica. The photothermal conversion mineral material prepared by the invention can be self-assembled into an integral system on the surface of liquid under the action of surface tension, so that the photothermal conversion mineral material shows excellent photothermal conversion performance, water absorption performance and heat insulation performance. The photo-thermal conversion efficiency is high, solar energy can be absorbed to vaporize water, and the diffusion space of the water vapor is large. The composite material shows excellent interface water evaporation rate under irradiation of light intensity of 100mW/cm < 2 >, and has excellent performance in seawater desalination and wastewater purification.
本发明提供了一种光热转换矿物材料及其制备方法和应用。该矿物材料通过在膨胀珍珠岩的大孔中原位合成介孔二氧化硅，然后对其表面进行了碳包覆得到。本发明制备的光热转换矿物材料可以通过表面张力作用在液体表面自组装为一个整体系统，从而表现出优异的光热转换性能，吸水性能和隔热性能。其光热转换效率较高，可以吸收太阳能进而将水汽化，并且水蒸汽的扩散空间较大。在100mW/cm2光强照射下表现出优异的界面水蒸发速率，并在海水淡化和废水净化中具有出色的表现。
