Synthesis of single-crystalline BaCO3 nanostructures with different morphologies via a simple PVP-assisted method

Alkaline-Earth Metal Carbonate, Hydroxide and Oxide Nano-Crystals Synthesis Methods, Size and Morphologies Consideration

“…The corresponding BET-particle diameter for a spherical particle was 70 nm (specific surface area (SSA): 20.5m 2 /g) in good agreement with the TEM observations [36]. Sun et al [5] synthesized single crystalline BaCO 3 with different morphologies and sizes by a facile and practicable approach in the presence of polyvinylpyrrolidone (PVP) as a guide reagent at room temperature. Some polymer-assisted syntheses, such as polyacrylic acid (PAA), polyvinyl alcohol (PVA), and polyvinylpyrrolidone (PVP), have been used to prepare a lot of nanomaterials.…”

“…In the process of the reaction, the quantity of CO 3 2− increased gradually with the pH value of the reaction system increasing. Therefore the number of Ba 2+ is large relative to CO 3 2− under low pH conditions, and certain facets with relatively higher free energies will preferentially form the active sites and show higher growth rate, thus, the bundles of rods and dendritic structures are obtained, which indicate that the preferential orientation is strongly dependent on the pH value of the aqueous solution [5]. Zhu et al [44] synthesized BaCO 3 nanostructures in water/ethylene glycol mixed solvents by microwave-assisted method.…”

Eco Friendly Synthesis, Spectroscopic Investigation of Copper and Its Oxide Nanoparticles with Excellent Electrical Conductivity

“…To the best of our knowledge, although such a heating method has been a focus of research, most of previous reports were limited to fixed working conditions of the microwave oven. [15][16][17][18][19][20] and there is no comprehensive report addressing the effects of these heating parameters on the synthesis of nanomaterials.…”

FABRICATION OF BaCO3 NANO-RODS IN WATER/POLY VINYL ALCOHOL MIXED SOLVENTS

“…In the past decade, several methods such as reversed micelles method 1 , sonochemiacal method 2 , microemulsion-mediated solvothermal route 3 , microwave-assisted 4 and polymer-assisted method 5 have been used to prepare BaCO 3 .…”

“…It was reported that these polymers either change the surface chemistry of the crystals, or act as a guide reagent for crystal growth 5 . In this research, the synthesis of BaCO 3 particles in water and water/PVA mixed solvents was investigated.…”
