Abstract

This study investigates the environmentally friendly synthesis of ZrO2‐NdO mixed nanomaterial using green reducing and capping agents derived from the plant Amaranthus viridis. X‐ray diffraction (XRD) analysis confirmed the successful synthesis of the mixed nanomaterial, revealing an optical band gap of 2.5 eV. The morphology was characterized by spherical‐shaped particles with an average size ranging from 66 to 77 nm. The synthesized ZrO2‐NdO mixed nanomaterial was evaluated for its potential application as an electrode material in energy devices, specifically for pseudocapacitors and water splitting studies. Electrochemical performance was assessed using cyclic voltammetry (CV) and galvanostatic charge–discharge (GCD) techniques. Notably, a specific capacitance of 573.5 F/g was achieved through CV at a scan rate of 2 mV/s. Fabricated electrocatalyst was further analyzed for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), and the results showed better over potential value of 164 mV for HER studies. The stability analysis further endorsed the large‐scale commercialization possibility of ZrO‐NdO‐based electrode material.

使用绿色封端剂合成 ZrO2-NdO 基混合纳米材料并将其功能化作为能源设备的电极材料：伪电容器和水分离

本研究利用从植物苋菜（Amaranthus viridis）中提取的绿色还原剂和封端剂，研究了 ZrO2-NdO 混合纳米材料的环保型合成。X 射线衍射（XRD）分析证实了混合纳米材料的成功合成，并显示出 2.5 eV 的光带隙。其形态特征为平均尺寸为 66 至 77 nm 的球形颗粒。对合成的 ZrO2-NdO 混合纳米材料进行了评估，以确定其作为电极材料在能源设备中的潜在应用，特别是在伪电容器和水分离研究中的应用。采用循环伏安法（CV）和电静态充放电（GCD）技术对其电化学性能进行了评估。值得注意的是，在 2 mV/s 的扫描速率下，通过 CV 获得了 573.5 F/g 的比电容。对制备的电催化剂进行了氢进化反应（HER）和氧进化反应（OER）的进一步分析，结果表明氢进化反应的过电位值为 164 mV。稳定性分析进一步证实了基于 ZrO-NdO 的电极材料大规模商业化的可能性。
