Recently, barium carbonate nanomaterial has been shown to be a proven versatile candidate for the catalysis and sensor applications. The catalytic and sensing efficiency can be improved by making barium carbonate composite with a suitable transition element. In this regard, the preparation of barium carbonate and its composite with nickel during the synthesis process is presented with the composite-hydroxide-mediated method, an effective, feasible, and low-temperature synthesis route. The nanomaterial produced is monitored for the structural and optical properties with various diagnostic methods. The X-ray diffraction results show the presence of orthorhombic structure of barium carbonate in both pure and 5% nickel samples. A mixed structure is formed with the phases of barium carbonate, Ba(NO 3 ) 2 , and Ni(NO 3 ) 2 for the sample with 15% nickel. The average crystallite size estimated is in the range of 14-22 nm. The scanning electron microscope pictures captured on silicon (Si) covered with the product material reveal interesting rods, needle, and flower-type morphological features. The bandgap energy obtained by diffused reflectance spectroscopy is in the expected range of 5.48-5.71 eV. The proposed method seems effective to provide a feasible route for the synthesis of a broad range of nanomaterials for research purposes.

“…The main source materials used for this experiment are; Ni (NO 3 ) 2 .6H 2 O, NaOH, and KOH. The synthesis procedure has been given in our previous reports [32][33][34]. Briefly, for the synthesis of NiO, an appropriate amount of mixed hydroxide (NaOH: KOH=51.5:48.5) were added in a Teflon beaker, and covered beaker was then placed in an electric furnace at 180 o C followed by further experiments at temperatures; 200°C, 220°C, and 250°C.…”

Composite-hydroxide-mediated (CHM) approach was used to synthesize NiO nanocrystals. The proposed method makes use of molten composite hydroxides; providing reaction media and lower the process temperature. Processing temperature and reaction time are the two potential parameters to control the growth of a nanomaterial. The method was used at temperatures in the range of 180-250°C and formation of the nanomaterial was monitored using XRD, SEM, EDX, FTIR, and UV-visible spectroscopy. The produced nanomaterial was purely polycrystalline with an average crystallite size in the range of 23.71-36.92 nm. Method suggested formation of pyramid shaped NiO nanocrystals in the temperature range 220-250°C. Evidence on the elemental composition, purity, and chemical bonding were obtained from EDX and FTIR analysis respectively. Estimation on direct bandgap was made from the optical analysis and found to be in the range 4.0-4.8 eV. The method is attractive and seems a cost effective route for the growth of transition metal oxides for research purpose. For further efficacy, the approach can be examined for other technologically significant nanostructures.

Polycrystalline cadmium hydroxide nanomaterials have successfully been synthesized by composite-hydroxide-mediated approach with growth time variation. The influence of growth time on structural, morphological, elemental, and optical properties was explored using X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, energy dispersive X-ray spectroscopy, and ultraviolet-visible spectroscopy. X-ray diffraction results revealed the hexagonal and monoclinic phases of cadmium hydroxide along with rhombohedral impurity phase of cadmium carbonate. Fourier transform infrared spectroscopy further endorsed the X-ray diffraction results and confirmed the Cd-O bonding vibrations. Time-dependent uniform distribution of spherical morphology was observed in the scanning electron micrographs of the product. The presence of cadmium and oxygen in the energy dispersive X-ray spectroscopy results fingerprinted the purity and formation of the desired nanomaterials. Crystallite size was decreased with the increase of growth time as estimated by the Debye-Scherrer method. Furthermore, the optical bandgap was measured by Tauc's relation using ultraviolet-visible absorption spectra and found to be in the range of 3.2-3.5 eV.
