This manuscript presents a novel method to enhance the electrochemical performance of CaMoO₄ for supercapacitors by synthesizing it from a bi-metallic metal–organic framework (MOF). The resulting CaMoO₄ nanoparticles retain MOF characteristics, with a high surface area, and demonstrate improved performance over conventionally synthesized CaMoO₄. Electrochemical tests showed the MOF-derived CaMoO₄ achieved a high capacitance of 377.82 F g⁻¹ at 1 A g⁻¹ and retained 91% of its capacitance after 5000 cycles. The assembled asymmetric supercapacitor also retained 88% of its capacitance after 10 000 cycles, highlighting the potential of this approach for enhancing energy storage devices.

释放 MOF 衍生的 CaMoO4 电极在高性能超级电容器应用中的潜力


该手稿提出了一种通过从双金属金属有机框架（MOF）合成CaMoO ₄ 来增强超级电容器电化学性能的新方法。所得的 CaMoO ₄ 纳米粒子保留了 MOF 的特性，具有高表面积，并且比传统合成的 CaMoO ₄ 表现出更好的性能。电化学测试表明，MOF 衍生的 CaMoO ₄ 在 1 A g ⁻¹ 下实现了 377.82 F g ⁻¹ 的高电容，并在 5000 次后保留了 91% 的电容循环。组装的非对称超级电容器在 10000 次循环后还保留了 88% 的电容，凸显了这种方法在增强储能设备方面的潜力。
