Mini Review: Recent Green Advances on the Preparation of V2O5, ZnO, and NiO Nanosheets

“…Nickel (II) oxide (NiO) and nickel (II) composites in meticulously have attracted substantial interest because of a broad range of applications, namely magnetic materials [17], photovoltaic [18] Li ion batteries [19], catalysis [20], gas sensors [21], p-type transparent conducting films, infrared detectors, storage oxygen materials, fuels cells, supercapacitors, ferromagnetic oxides, gas sensors and luminescence materials, photochromic materials, [22], electrochromic windows [23], biomedicine, desalination, waste water treatment, energy related fields, catalytic reduction, adsorption, photocatalytic reduction, degradation, magnetic material, reinforcing agents in composites [24,25]. Different methods have been reported for the synthesis of NiO, such as sol-gel [26], microemulsion [27], hydrothermal [28], co-precipitation, precipitation [29], sonochemical [15], microwave [30], metal-organic chemical vapor deposition (MOCVD), sputtering method [30], pulsed laser deposition (PLD), infrared irradiation, thermal decomposition, thermal evaporation and condensation [29,30].…”

Improved size-tunable synthesis of monodisperse NiO nanoparticles

“…The nickel oxide (NiO) is obviously p-type semiconductor and has a relatively wide band gap energy in the range of 3.6-4.0 eV among the various oxides materials [2]. Because of its unique electronic structure [3], NiO nanoparticles have an extensively application research field [4], such as photocatalysts [5], photovoltaic devices [6], gas sensors [7], solar cell [8] and electrochromic film [9].…”

Thermal and Multifunctional Properties of Nanoparticles

“…Magnetic particles (MP) (6) can be also used as efficient labels for MRI diagnostics and can be precisely quantified even inside a living organism by an external induction probe (7,8). At present, MP are widely studied for hyperthermia of tumors by heating in an AC magnetic field and for targeted delivery of drugs by magnetic field gradients, to avoid systemic intoxication of the organism (9,10). Specific immunological targeting of nanoparticles by antibodies against pathogenic cells is another noteworthy application.…”

“…Among various nano-particles, magnetic nanoparticles especially nanosized ferrite materials have been frequently used in variety of fields such as biosensors, gas sensors, magnetic catalysis, transformer core drug delivery, magnetic resonance imaging (MRI), lithium ion batteries, magnetic materials and microwave devices [3][4][5]. Cobalt ferrite (CoFe2O) is one of the most widely used ferrites because of its high coercivity, chemical stability, mechanical hardness, moderate saturation magnetization and photo-induced magnetic effects [1,[6][7][8][9]. Though variety of applications of cobalt ferrite have been investigated, but its application as an adsorbent material for the treatment of metallic pollutants is not yet much explored.…”
