Ultrasonically assisted synthesis of lead oxide nanoflowers using ball milling

Abstract

The experimental results on the ultrasonically assisted synthesis of lead oxide nanoflowers using ball milling have been reported in the present work. Lead oxide nanoflowers were prepared employing mixed ligands by subjecting the formed precipitate to ultrasonication and grinding/ball milling. The effect of ball milling as well as fine grinding in agate mortar on the microstructure and surface morphology of the lead oxide was studied. The characteristics of synthesized PbO were studied using X-ray diffraction, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy and field emission scanning electron microscopy techniques. XRD results demonstrated the tetragonal phase of PbO with crystallite size of around 25 nm and strain of 3.6 9 10 -3 calculated from Williamson-Hall plot. FESEM images manifested the formation of nanodiscs and nanoflowers with a diameter of around 300 nm and thickness of 50 nm. XPS spectra revealed the formation of PbO with photoelectron peak of Pb 4f and O 1 s lied at 137.68 and 529.96 eV. Moreover, FTIR spectrum exhibited Pb-O bond peak in the range of 400-530 cm -1 .

Structural Analysis and Adsorption Studies of (PbO, MgO) Metal Oxide Nanocomposites for Efficient Methylene Blue Dye Removal from Water

“…The Pb-O bond stretching band is responsible for the distinctive transmittance peaks that are detected within the 680 cm −1 range. Oxides are also visible in this range due to decreased transmittance [ 30 , 31 ]. The stretching vibrations caused by the C-O bond are represented by an intense infrared absorption seen in the range of 2353.…”

Smartphone-Integrated Automated Sensor Employing Electrochemically Engineered 3D Bimetallic Nanoflowers for Hydrogen Peroxide Quantification in Milk

“…Pb metal is also known for its superior reaction sites and intrinsic chemical properties . Several Pb-based nanostructures have been synthesized so far and possess a high specific surface area, electrocatalytic activity, and energy storage capacity. , Hence, they are widely employed in sensors, solar energy conversion materials, and batteries and as in vivo imaging agents. − Hence, we tried to explore the enhanced properties of both metals to synthesize bimetallic flower-like nanostructures. Bimetallic NFs have become increasingly popular due to their synchronous effect and strong chemical makeup customizability, enabling them to exhibit enhanced physicochemical properties in comparison to monometallic components. − In light of this, an appealing and robust sensor platform based on 3D bimetallic BiPb NFs was devised employing an easy, one-step co-electrodeposition.…”

Synthesis of Enzyme-based Organic-Inorganic Hybrid Nanoflower Particles

“…It causes change, both physically and chemically by the forming, growing and collapse of bubbles in a solution [13,14]. The ultrasonic method under various conditions affects the shape and size of the NFs produced [15]. Some factors which affects the final structure and performance of the synthesized NF includes the ultrasonic waves itself, whereby, high intensity waves prevent the growth of crystal nuclei despite the prolonged duration [16].…”

“…Some factors which affects the final structure and performance of the synthesized NF includes the ultrasonic waves itself, whereby, high intensity waves prevent the growth of crystal nuclei despite the prolonged duration [16]. Different frequencies may also cause the difference in the structure of the nanoparticle (NP) whether it is 1D, 2D or 3D in shape [15]. Besides, the sonication temperature also affects the process.…”
