摘要 | Developing plasmonic materials as cermet composites is desirable for selective solar absorbers. Silver nanoparticles/alumina (Ag-Al2O3) cermet possesses reasonable resistance to high-temperature oxidation; however, an inherent long-range diffusion of Ag element limits their applications at elevated temperatures. In this work, a well-designed AgAl-Al2O3 nanocermet, after low-temperature pretreatment in air, exhibits stable plasmonic absorption feature with negligible degradation at 500 degrees C for 990 h in nitrogen ambient. Based on this cermet, an Al2O3/low metal volume fraction AgAl-Al2O3/high metal volume fraction AgAl-Al2O3/Al2O3/AgAl tandem absorber was successfully constructed, demonstrating a high solar absorptance of approximate to 95% and a low infrared emittance of approximate to 11%@673 K after annealing at 500 degrees C for 1002 h in nitrogen ambient. It is believed that thermal-induced out-diffusion of Al atoms from AgAl bimetallic nanoparticles and their consequent oxidation afford an opportunity to generate self-organized alumina-capped Ag nanoparticles. The alumina-capped Ag particles and unalloyed Ag agglomerations are mixed together to form mosaic structure, suppressing the long-distance diffusion of active Ag and wild growth of particle agglomerations so as to guarantee the microstructural integrity and plasmon absorption stability. These results demonstrate that the proposed AgAl-Al2O3-based solar absorber is remarkably promising to be used in high-temperature solar thermal conversion. |
