Solar-thermal utilization is one of the important ways of energy utilization at present and in the future. Nanofluids play a key role in photothermal conversion. In this work, the low-dimensional plasmonic TiN/MWCNTs nanofluids were firstly proposed. The photothermal conversion properties of low-dimensional plasmonic nanofluids was systematically investigated. The analytical results indicated that the heat transfer and optical properties of plasmonic nanofluids were significantly enhanced. Specifically, thanks to the expanded light absorption by the LSPR of nano-TiN and the enhanced thermal transport by its low-frequency phonon (LFP) resonance with MWCNTs, the photothermal conversion efficiency can reach 68.1% with 10 ppm TiN/MWCNTs nanofluids, which was 22.9% higher than that of the MWCNTs nanofluids. And the photothermal conversion efficiency of TiN/MWCNTs nanofluids (40 ppm) reached 76.4%. Furthermore, through the simulation and experimental results, this paper explained the mechanism of the enhanced solar-thermal conversion performance of nanofluids from the perspective of phonon heat transfer. |
