Abstract

Encapsulating the essence of multifunctionality, the synthesized Vanadium Pentoxide (V2O5) nanorods (NRs) are adaptable innovators of visible-light photocatalytic degradation and sustainable supercapattery device fabrication. Meanwhile, the physicochemical properties are investigated by precise instruments. The V2O5 NRs demonstrate improved photocatalytic performance over a 100-min duration, effectively catalyzing the methylene blue (MB) degradation with a remarkable degradation percentage of 98.37 % (25 mg catalysis) and shows a lower wavelength shift due to MB molecular braking. In a groundbreaking twist, this work utilises tainted V2O5 NRs, ingeniously repurposing them to energy storage tenacities. In addition, the electrochemical assessment of tainted V2O5 NRs demonstrated subtle changes after MB degradation, increasing the specific capacity (Cs) value from 794 to 933C.g−1 due to developing reduced particle agglomeration. Moreover, the better Cs value of tainted V2O5 NRs reached 95.02 % after 500 cycles (5 A.g−1). The fabricated asymmetric supercapattery (ASC) device demonstrates superior ion diffusion processes, as evidenced by Dunn's method calculations, particularly at a scan rate of 5 mV.s−1. Additionally, the assembled device underscored their unique positioning between battery and capacitor materials, distinctly supported by a “b” value of 0.8 and superior capacity retentivity. They reached a superior power (P = 191.75 W.kg−1) with energy (E = 50 Wh.kg−1) and better cyclic stability, maintaining their performance over 4000 cycles at 5 A. g−1 (91.3 %). Furthermore, under exposure to the light of a yellow light emitting diode (LED) for 30 s, the real-time consequences of after cyclic stability material of tainted V2O5 NRs are investigated, providing meaningful insights into their performance dynamics.
V2O5纳米棒增强阴极电极:开拓有机染料降解和可持续超级电池设备的优化催化
合成的五氧化二钒(V2O5)纳米棒封装了多功能的本质,是可见光光催化降解和可持续超级电池器件制造的适应性创新者。同时用精密仪器对其理化性质进行了研究。V2O5 NRs在100 min的光催化时间内表现出较好的光催化性能,有效地催化亚甲基蓝(MB)的降解,在25 mg的催化作用下,降解率达到了98.37%,并且由于MB分子的制动,表现出较低的波长偏移。突破性的是,这项工作利用了受污染的V2O5核反应堆,巧妙地将它们重新用于储能能力。此外,受污染的V2O5 NRs的电化学评价在MB降解后发生了微妙的变化,比容量(Cs)值从794增加到933C。G−1是由于产生还原性颗粒团聚。经过500次循环(5 A.g−1)后,污染的V2O5 NRs的优良Cs值达到95.02%。制造的非对称超级电池(ASC)装置显示出优越的离子扩散过程,正如Dunn的方法计算所证明的那样,特别是在5 mv / s−1的扫描速率下。此外,组装的器件强调了其在电池和电容器材料之间的独特定位,明显支持“b”值为0.8和优越的容量保留率。它们在功率(P = 191.75 W.kg−1)和能量(E = 50 Wh.kg−1)方面都取得了优异的成绩,并且具有更好的循环稳定性,在5 a . g−1的条件下,在4000次循环中保持了性能(91.3%)。此外,在黄色发光二极管(LED)照射30秒的情况下,研究了污染V2O5 nr的循环稳定后材料的实时后果,为其性能动态提供了有意义的见解。
