“…NiO is a promising transition metal oxide because of its advantages of low cost, environmental compatibility, and high chemical and thermal stability (Zheng et al, 2017). In practice, NiO particles are synthetized by various chemical and physicochemical technologies (Hu, Wang, Xuan, Zhang, & Xu, 2017) and have been employed in many fields such as supercapacitors (Cheng et al, 2015), lithium-ion batteries (Jadhav, Thorat, Mun, & Seo, 2016), gas sensors (Tian, Wang, Li, Nadimicherla, & Guo, 2016), adsorption (Zheng et al, 2017), and catalysis (Ye et al, 2016).…”
