Electrochemical coating and recovery by electrodeposition have been invaluably employed for facial thin film fabrication and the recycling of used materials. Herein, we have established a full data set of lanthanide (Ln: La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb) elements electrodeposited on carbon sheets. Cyclic voltammetry was performed for 10 mM Ln(III) ions in a 0.1 M NaClO₄ electrolyte over a carbon sheet between +0.5 V and −1.7 V (vs. Ag/AgCl). Amperometry was performed at a given potential to electrodeposit the Ln element on the carbon sheet. Their physicochemical properties were fully investigated by scanning electron microscopy, Fourier-transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy. The newly established full data set for Ln(III) ions over carbon electrodes provides useful fundamental information for the development of coating and recovery methods of Ln elements.

碳片上镧系元素的电沉积和表征

电化学涂层和通过电沉积的回收已经非常有用地用于面部薄膜的制造和废旧材料的回收。在这里，我们已经建立了电沉积在碳片上的镧系元素（Ln：La，Ce，Pr，Nd，Sm，Eu，Gd，Tb，Dy，Ho，Er，Tm和Yb）的完整数据集。在0.1 M NaClO _4中对10 mM Ln（III）离子进行循环伏安法在+0.5 V至-1.7 V（vs. Ag / AgCl）之间的碳板上沉积电解质。在给定的电位下进行电流分析，以将Ln元素电沉积在碳片上。通过扫描电子显微镜，傅立叶变换红外光谱，能量色散X射线光谱和X射线光电子能谱对它们的理化性质进行了全面研究。新建立的碳电极上Ln（III）离子的完整数据集为开发Ln元素的涂层和回收方法提供了有用的基本信息。
