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.
高效光熱轉(zhuǎn)換納米流體是太陽能采集中的一個有趣的話題。在本文中，我們提供錫是用于太陽能熱轉(zhuǎn)化的極好的替代等離子體納米流體。氮化鈦(TiN)的光吸收特性和光熱轉(zhuǎn)換性能優(yōu)于其它五種傳統(tǒng)材料如碳納米管、石墨烯、Au、Ag和金屬硫化物(CuS)。Au與TiN納米粒子的雙局部表面等離子體共振(LSPR)效應(yīng)納米復(fù)合材料(Au/TiN)在相同濃度下具有優(yōu)異的光學(xué)吸收。最大的20分鐘照射后100ppm錫的溫升為14.2°C，光熱轉(zhuǎn)換效率比其它五種常規(guī)的納米流體高得多。具有不同Au的所有Au/TiN納米流體載荷比TiN具有更高的最大溫升，表明雙LSPR效應(yīng)對較好的效果是有益的光熱轉(zhuǎn)換性能。
