Seeking a straightforward, cost-effective, and convenient method to fabricate multicomponent alloy powders holds great significance for their potential applications in industry. In this work, we successfully synthesized multicomponent alloy powders of CoCrFeNi and AlFeNiV via a molten salt method. Compared with traditional methods reported previously, such as mechanical alloying and gas atomization, the molten salt method demonstrates several advantages, including a simpler synthesis process, cost-effective, higher purity, lower reaction temperatures, and ease of large-scale production. Moreover, we further synthesized a P-doped multicomponent alloy catalyst (CoCrFeNi-P) through gas phosphorization and proved that it shows enhanced electrocatalytic performance in seawater electrolysis, which can achieve a current density of 100 mA cm^–2 at an overpotential of 462 mV. The CoCrFeNi-P catalyst maintained its catalytic activity for seawater electrolysis over a continuous period of 100 h. The multicomponent alloy powders reported herein hold great promise for applications in catalysis fields.

熔盐法合成多元合金粉末及其电解海水电催化性能


寻求一种简单、经济且方便的方法来制造多元合金粉末对于其在工业中的潜在应用具有重要意义。在这项工作中，我们通过熔盐法成功合成了CoCrFeNi和AlFeNiV多元合金粉末。与之前报道的机械合金化和气体雾化等传统方法相比，熔盐法具有多种优点，包括合成工艺更简单、成本效益高、纯度更高、反应温度更低、易于大规模生产。此外，我们进一步通过气体磷化合成了一种P掺杂多元合金催化剂（CoCrFeNi-P），并证明其在海水电解中表现出增强的电催化性能，在100 mA cm ^–2 电流密度下可以实现100 mA cm ^–2 的电流密度。 462 mV 的过电势。 CoCrFeNi-P催化剂在连续100小时内保持其对海水电解的催化活性。本文报道的多组分合金粉末在催化领域的应用具有广阔的前景。
