Li*, Dual plasmonic Au/TiN nanofluids for efficient solar photothermal conversion, Solar Energy, 2019, 184: 240-248

Fabrication highly efficient photothermal conversion nanofluids is a fascinating topic in solar energy harvesting applications. Herein, we present TiN is an excellent alternative plasmonic nanofluid for solar thermal conversion. The optical absorption property and the photothermal conversion performance of titanium nitride (TiN) are superior to another five traditional materials such as carbon nanotube, graphene, Au, Ag and metal sulfide (CuS).

Dual localized surface plasmon resonance (LSPR) effect between Au and TiN nanoparticles make the hybrid nanocomposite (Au/TiN) possess superior optical absorption to TiN at the same concentration. The maximal temperature rise of 100 ppm TiN after irradiation for 20 min is 14.2 °C. The photothermal conversion efficiency of TiN is much higher than another five conventional nanofluids. All Au/TiN nanofluids with different Au loadings show higher maximal temperature rise than TiN, indicating dual LSPR effect is beneficial for better photo-thermal conversion performance.

高效光热转换纳米流体是太阳能采集中的一个有趣的话题。在本文中，我们提供锡是用于太阳能热转化的极好的替代等离子体纳米流体。氮化钛(TiN)的光吸收特性和光热转换性能优于其它五种传统材料如碳纳米管、石墨烯、Au、Ag和金属硫化物(CuS)。Au与TiN纳米粒子的双局部表面等离子体共振(LSPR)效应纳米复合材料(Au/TiN)在相同浓度下具有优异的光学吸收。最大的20分钟照射后100ppm锡的温升为14.2°C，光热转换效率比其它五种常规的纳米流体高得多。具有不同Au的所有Au/TiN纳米流体载荷比TiN具有更高的最大温升，表明双LSPR效应对较好的效果是有益的光热转换性能。
