Abstract

Triethanolamine-assisted hydrothermal synthesis of hierarchical nickel oxide particles was studied. The thermal behavior, crystal structure, and spectral characteristics of α-Ni(OH)₂ obtained by the hydrothermal treatment of the reaction system and subsequent drying of the solid phase were investigated. It was shown that the thermal treatment at 350°C for 1 h results in the decomposition of the obtained intermediate product to form the desired nanocrystalline oxide (average coherent scattering region size of about 6 nm). Kelvin probe force microscopy was used to construct the maps of the potential distribution over the surface of particles of the studied material and to determine the work function of its surface.

摘要

研究了三乙醇胺辅助水热合成分级氧化镍颗粒。研究了通过反应体系的水热处理和随后的固相干燥得到的α-Ni(OH) ₂的热行为、晶体结构和光谱特征。结果表明，在 350°C 下热处理 1 小时导致所得中间产物分解，形成所需的纳米晶氧化物（平均相干散射区域尺寸约为 6 nm）。开尔文探针力显微镜用于构建所研究材料颗粒表面的电位分布图，并确定其表面的功函数。
