Abstract

Lithium-ion batteries and supercapacitors both depend on the utilization and fabrication of nanomaterials to enhance efficacy. For energy accumulation purposes, electrode materials were developed through these endeavors. This investigation entailed the synthesis and utilization of bimetallic PANI@Sn-MOF/Ag(NPs) in supercapattery devices. In electrochemical examination, the PANI@Sn-MOF/Ag(NPs) electrode exhibited a specific capacity of 1433 C/g at a current density of 1.0 A/g. The electrochemical performance is enhanced by the substantial specific surface area of 79.9 m²/g, as evidenced by BET analysis. The supercapattery device (PANI@Sn-MOF/Ag(NPs)//AC) is constructed with PANI@Sn-MOF/Ag(NPs) and activated carbon which demonstrated a specific capacity of 126 C/g. It showcased a power density of 970 W/kg and an energy density 44.6 Wh/kg. Following 10,000 GCD cycles, the PANI@Sn-MOF/Ag(NPs) device retained up to 89% of its capacity. In a hydrogen evolution reaction, the PANI@Sn-MOF/Ag(NPs) composite exhibited the lowest over potential of 93.83 mV. The PANI@Sn-MOF/Ag(NPs) electrode exhibits significant potential for deployment in hydrogen evolution reaction applications and energy storage devices.

PANI@Sn-MOF/Ag（NPs）在下一代超级电池中的协同性能和析氢反应

锂离子电池和超级电容器都依赖于纳米材料的利用和制造来提高效率。为了能量积累的目的，通过这些努力开发了电极材料。本文研究了双金属PANI@Sn-MOF/Ag（NPs）在超级电池器件中的合成和应用。在电化学测试中，PANI@Sn-MOF/Ag（NPs）电极在1.0 a /g电流密度下的比容量为1433 C/g。BET分析表明，该材料的比表面积可达79.9 m2/g，提高了电化学性能。超级电池装置（PANI@Sn-MOF/Ag(NPs)//AC）由PANI@Sn-MOF/Ag（NPs）和活性炭组成，比容量为126 C/g。其功率密度为970 W/kg，能量密度为44.6 Wh/kg。经过10,000次GCD循环后，PANI@Sn-MOF/Ag（NPs）器件保留了高达89%的容量。在析氢反应中，PANI@Sn-MOF/Ag（NPs）复合材料的过电位最低，为93.83 mV。PANI@Sn-MOF/Ag（NPs）电极在析氢反应和储能装置中具有重要的应用潜力。
