Electric‐Field Aerosol‐Assisted CVD: Synthesis, Characterization, and Properties of Tin Oxide Microballs Prepared from a Single Source Precursor

Abstract

Mesoporous nanostructures of tin(IV) oxide microballs are synthesized, using a single source precursor [Sn (OAc)(dmae)] 2 (where OAc ¼ Acetato and dmae ¼ dimethylaminoethanolato). The as-prepared microballs are characterized using X-ray diffraction, field emission scanning electron microscopy (FESEM), Fourier transform infrared and UV-vis spectroscopy, X-ray photoelectron spectroscopy and impedance spectroscopy. The focused ion beam (FIB) images of the exterior and interior surfaces of the microballs disclosed the presence of porous structures with mesopore of sizes ranging from 56-66 nm and 8.0 to 160 nm, respectively. The microballs exhibit high BET and Langmuir surface areas of 136 and 191.6 m 2 g À1 , respectively, andshow capacities >600 mAhg À1 over 60 cycles, as compared with unmodified tin oxide-based nanomaterials which show capacity < 500 mAh g À1 after 50 cycles.

Pure and multi metal oxide nanoparticles: synthesis, antibacterial and cytotoxic properties

“…Finally, the product that is also in the gas phase is carried to a much cooler zone where it due to such temperature gradient transforms into a solid state and can get collected. These techniques are extensively employed to produce uniform and contamination-free metal oxide nanoparticles and films; such as ZnO nanowires and films [ 109 ] and defect-free ZnO nanoparticles [ 110 ], nanocubes and nanospheres of magnetite [ 111 ], Cu 2 O [ 112 ], MgO and CaO [ 113 ], SnO 2 [ 114 ], SrO [ 115 ], CoO and Co 3 O 4 [ 116 ]. When multi-metal oxides are considered, this technique allows for the production of B-doped ZnO [ 117 ], europium doped yttria (YO: Eu) [ 118 ], Li-doped MgO [ 119 ], Ca-doped [ 92 , 120 ].…”

Composite electrodes with superior catalytic activity in methanol electro-oxidation fabricated using ternary NiO–CuO–ZnO mixed metal oxides

“…1,2 The critical depletion of limited fossil fuel sources and lethal effects of the extreme use of these fossil fuels on the environment has created significant research interest in alternate clean and renewable energy sources. 3,4 Energy storage and energy production-conversion devices like batteries, 5 supercapacitors, 6 photoelectrochemical water splitting, [7][8][9][10] wind turbines, and fuel cells 11,12 have received considerable attention from researchers. Fuel cells are energy production devices that produce electricity via an electrochemical reaction in the presence of hydrogen and oxygen.…”

“…28 Additionally, the synergistic combination of binary and ternary TMOs and TMDCs has been studied to enhance the kinetic efficiency and stability of electrocatalytic electrodes used in fuel cells. 21,29 Due to their physical and chemical characteristics, like a better surface-volume ratio, structural features, increased specific capacitance, durability, stability, nontoxicity, and electrocatalytic behavior, Ni, Cu, and Zn oxides are broadly utilized in photoelectrochemical water splitting, sensors, 30,31 batteries, 5 supercapacitors, 32 solar cells, 33 and optoelectronic applications. 34 The use of mixed metal oxides in the MOR has attracted significant attention due to their synergistic effects.…”
