英文摘要 | Spectrally selective absorber with superior thermal stability and optical properties is crucial for photothermal conversion applications, including evaporation, anti-icing, medical sterilization, photothermal catalysis, and solar-thermal power. Efforts are being made to develop entropy-stabilized high-entropy ceramics as high-performance functional materials, which promise a wide range of potential applications in the fields of energy storage and conversion owing to their diverse compositions and outstanding physical and chemical properties. Herein, an entropy-stabilized strategy is used to boost the performance of spectrally selective absorbers by carefully choosing a high-entropy alloy (TiVCrAlZr) target with a reasonable element design, which exhibits a good solar absorptance (α = 96.1%) and low thermal emittance (ϵ = 7.8%). Long-term thermal stability investigation demonstrates that the entropy-stabilized absorber could endure at 400 °C for 168 h. Under the irradiation of simulated sunlight, the surface temperature of the absorber can reach up to 105 °C, which is essential for middle- and low-temperature applications. Overall, this work provides significant insights into the spectral selectivity of high-entropy alloy nitrides and offers a new strategy for designing and developing moderate and low solar selective absorbing coatings via a high-entropy strategy. |
