“…Multi-layered dip-coating is also applied to increase the uniformity and thickness of the film [62,93]. Simiari et al has deposited NiO on a glass substrate via the dip coating method [94]. They dissolved 2.489 gr of nickel acetate tetrahydrate (C4H6NiO4•4H2O) in 20 mL of 2methoxyethanol at 70 °C for 15 min.…”

“…Spray coating is a highly controllable and adaptable process that can be used to deposit metal oxide coatings onto a wide range of substrate materials, including glass, ceramics, and metals. It is commonly used in the production of a range of functional [94]. The AFM allows measuring the surface roughness of NiO film RMS = 6.57 nm.…”

“…Then, they immersed the substrate vertically and removed it out of the solution several times at a speed of 100 mm/min. The deposited film was dried at 300 • C for 15 min each cycle until it reached the desired thickness, and then it was annealed in an air environment for 1 h at 600 • C. The roughness, the wetting behavior, and the crystallinity of the coating film are investigated in reference[94]. The AFM allows measuring the surface roughness of NiO film RMS = 6.57 nm.…”

The review paper provides a comprehensive analysis of nickel oxide (NiO) as an emerging material in environmental monitoring by surveying recent developments primarily within the last three years and reports the growth processing and strategies employed to enhance NiO sensing performance. It covers synthesis methods for pristine NiO, including vapor-phase, liquid-phase, and solution-processing techniques, highlighting advantages and limitations. The growth mechanisms of NiO nanostructures are explored, with a focus on the most recent research studies. Additionally, different strategies to improve the gas sensing performance of NiO are discussed (i.e., surface functionalization by metallic nanoparticles, heterostructure formation, carbon-based nanomaterials, and conducting polymers). The influence of these strategies on selectivity, sensitivity, response time, and stability of NiO-based sensors is thoroughly examined. Finally, the challenges and future directions that may lead to the successful development of highly efficient NiO-based gas sensors for environmental monitoring are introduced in this review.
