Abstract

Scientists improve energy storage technologies to meet the increasing energy crisis caused by non-renewable resources. Supercapacitors (SCs), are revolutionary energy storage system that have extended lifetime and greater power density. Here, the hydrothermal approach was adopted to synthesize CuZrO₃/rGO nanohybrid electrode for SCsCuZrO₃/rGO was evaluated using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) to calculate its shape, crystal structure, and functional groups. Numerous perovskites have been employed as SCs materials, but, due to their cycle stability, rGO was included to develop the electrochemical technique of perovskites. CuZrO₃/rGO displayed a specific capacitance (C_sp) of 1376.09 F g⁻¹ at 1 A g⁻¹. The CuZrO₃/rGO//AC asymmetric structure showed an ideal C_sp of 211.36 F g⁻¹ with an E_d of 1578.70 W h kg⁻¹ and C_d of 1 A g⁻¹. This work shows that the CuZrO₃/rGO nanocomposite's superb features and high stability and affordability create it suitable for next-era SCs applications.

高性能超级电容器用CuZrO3/rGO纳米杂化材料的三电极研究及非对称器件制备

科学家改进储能技术，以满足日益严重的不可再生资源造成的能源危机。超级电容器（SCs）是一种具有更长的使用寿命和更高功率密度的革命性储能系统。本文采用水热法合成CuZrO3/rGO纳米杂化电极，利用x射线衍射（XRD）、傅里叶变换红外光谱（FTIR）和扫描电镜（SEM）对其形貌、晶体结构和官能团进行了评价。许多钙钛矿已被用作超导材料，但由于其循环稳定性，将还原氧化石墨烯纳入钙钛矿的电化学技术中。CuZrO3/rGO在1ag−1时的比电容（Csp）为1376.09 F g−1。CuZrO3/rGO/ AC不对称结构的理想Csp为211.36 F g−1，Ed为1578.70 W h kg−1，Cd为1 A g−1。这项工作表明，CuZrO3/rGO纳米复合材料的卓越特性、高稳定性和可负担性使其适合下一个时代的纳米材料应用。

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
