By a News Reporter-Staff News Editor at Science Letter -- New research on Materials Science and Physical Chemistry is the subject of a report. According to news reporting originating from Maharashtra, India, by NewsRx correspondents, research stated, "A facile, cost-effective, surfactant-free chemical route has been demonstrated for the fabrication of porous beta-Co(OH)(2) hierarchical nanostructure in gram level simply by adopting cobalt acetate as a precursor salt and ethanolamine as a hydrolyzing agent at room temperature. A couple of different morphologies of beta-Co(OH)(2) have been distinctly identified by varying the mole ratio of the precursor and hydrolyzing agent."
Our news editors obtained a quote from the research from Bhabha Atomic Research Center, "The cyclic voltammetry measurements on beta-Co(OH)(2) displayed significantly high capacitance. The specific capacitance obtained from charge-discharge measurements made at a discharge current of 1 A/g is 416 F/g for the Co(OH)(2) sample obtained at room temperature. The charge-discharge stability measurements indicate retention of specific capacitance about 93% after 500 continuous charge-discharge cycles at a current density of 1 A g(-1). The capacitive behavior of the other synthesized morphology was also accounted. The nanoflower-shaped porous beta-Co(OH)(2) with a characteristic three-dimensional architecture accompanied highest pore volume which made it promising electrode material for supercapacitor application. The porous nanostructures accompanied by high surface area facilitates the contact and transport of electrolyte, providing longer electron pathways and therefore giving rise to highest capacitance in nanoflower morphology."
According to the news editors, the research concluded: "From a broad view, this study reveals a low-temperature synthetic route of beta-Co(OH)(2) of various morphologies, qualifying it as supercapacitor electrode material."
