Abstract

Nickel hydroxide nanoparticles with different amounts of cobalt atoms in the structure forming a unique material, were synthesized by using ultrasonic radiation. The particles of 5 nm diameter were prepared and characterized by X-Ray diffraction, Raman and Infrared spectroscopies, and thermogravimetry. The incorporation of cobalt leads to distinct crystalline planes, showing an opened and disarranged structure, indicating the stabilization of the alpha-Ni(OH)2 phase.

摘要

通过超声辐射合成了结构中含有不同数量钴原子的氢氧化镍纳米颗粒，形成了一种独特的材料。制备了直径为5nm的颗粒，并通过X射线衍射、拉曼光谱和红外光谱以及热重分析对其进行了表征。钴的掺入导致了不同的晶面，呈现出开放且无序的结构，表明α-Ni(OH)₂相得到了稳定。
