Abstract Spindle-like CuO nanoparticles (NPs) were prepared in a single-step approach by using a cathode glow discharge electrolysis plasma (CGDEP) technique with 2.5 g L−1 NaNO3 as an electrolyte and 1.0 g L−1 cetyltrimethylammonium bromide (CTAB) as a stabilizer. When a sufficiently high voltage (>280 V) was applied, plasma was generated around the Pt needle point cathode. The copper foil anode was gradually consumed and black CuO NPs appeared. The active species formed during the CGDEP process were recorded on an optical fiber spectrometry. The structure and morphology of the CuO NPs were characterized by XRD and SEM. The results showed that spindle-like CuO NPs with the length of 250–350 nm were formed at 300 V discharge voltage.

阴极辉光放电电解等离子体合成纺锤形CuO纳米颗粒

摘要 采用阴极辉光放电电解等离子体 (CGDEP) 技术,以 2.5 g L-1 NaNO3 作为电解质和 1.0 g L-1 十六烷基三甲基溴化铵 (CTAB),一步法制备纺锤状 CuO 纳米粒子 (NPs)。作为稳定器。当施加足够高的电压 (>280 V) 时,在 Pt 针尖阴极周围会产生等离子体。铜箔阳极逐渐消耗,出现黑色的 CuO NPs。在 CGDEP 过程中形成的活性物质被记录在光纤光谱仪上。通过 XRD 和 SEM 表征了 CuO NPs 的结构和形貌。结果表明,在 300 V 的放电电压下形成了长度为 250-350 nm 的纺锤状 CuO NPs。
