2020年3月1日 · SEM with EDAX gives the morphological and the elemental analysis of NiO samples. Finally, the antibacterial activity of nickel oxide nanoparticles extracted from Cassia auriculata at 200 °C (Ni-1) and at 700 °C (Ni-2) were determined by well diffusion method.

Nickel oxide (NiO) nanoparticles have been prepared by chemical co-precipitation method. The synthesised nanoparticles were investigated by X-ray diffraction analysis (XRD), scanning electron...

2021年1月1日 · P-type NiO powders with an average crystallite size of 16 nm as shown by x-ray diffraction analysis were produced via biosynthesis using cactus plant extract. SEM showed that the NiO powders consisted of particles with sizes in the 20–35 nm range. XPS confirmed the chemical composition and chemical state of the NiO.

Nickel oxide (NiO) is extremely popular p-type semiconductor with a wide band gap of 3.6-4 eV [1, 2] due to its presence of unique electrical, optical and magnetic properties. It...

2016年1月1日 · In this paper, thermal treatment procedures were utilised to prepare crystalline nickel oxide semiconductor nanoparticles, derived from an aqueous solution. The solution consists of three compounds, primarily nickel nitrate, polyvinyl pyrrolidine and deionised H 2 O acting as metal precursor, capping agent and solvent, respectively.

2014年8月15日 · The morphology and microstructure of the NiO nanoparticles have been investigated using SEM and TEM techniques. Figures 4 and 5 are the respective SEM and TEM images of the nanoparticles obtained from 1 and 2 which indicate their particle size around 10–15 nm. The particles are both spherical and cubic.

Field emission scanning electron microscopy (FE-SEM) measurements show that particles have well defined shapes and are dispersed in an organic matrix. X-ray absorption near edge spectroscopy (XANES) shows also the formation of fcc NiO nanoparticles structures.

The SEM image in Fig. 2(a) shows the NiO NPs are cubic and spherical in shape, and were slightly agglomerated. The formation of cubic and spherical nanoparticles was also observed in the TEM...

2023年9月6日 · Highly efficient 2D/2D layered heterostructure of nickel oxide (NiO) and molybdenum sulphide (MoS2) has been fabricated for the photoelectrochemical (PEC) water splitting and degradation of Bromophenol Blue (BPB) under visible light. The XRD spectra confirm mixed characteristic peaks of MoS2 and NiO in the n
