Corrosion behavior of Mg/graphene composite in aqueous electrolyte

The effect of electrochemical reduction of carbon dioxide (CO 2 ) by changing the structure and morphology of FeTiO 3 nanoparticle prepared through sol-gel and hydrothermal methods is explained in this study. FeTiO 3 nanoparticles were used as a cathode where as a stainless steel plate and CO 2 − saturated NaHCO 3 were used as an anode and an electrolyte, respectively. The cyclic voltammetry and linear sweep voltammetry analysis were carried out comprehensively on FeTiO 3 -SG-and FeTiO 3 -HT-coated electrodes to decouple the electrochemical reduction processes of CO 2 in aqueous solution. The charge transfer resistance and the product gases were studied using electrochemical impedance spectroscopy and gas chromatography, respectively. The observed results were analyzed in light of structure/morphology, particle size, and surface area of FeTiO 3 nanoparticles and their influence on the effective cathodic behavior in CO 2 to CO reduction.

“…The synthesized Ni(OH) 2 -WDG nanocomposites powder was assorted with a polyvinylidene difluoride (PVDF) at a ratio of 85:15 in a small quantity of N-Methyl-2-pyrrolidone as a solvent to make a paste. The paste substance was covered over the separate SS plates by means of a doctor blade [24]. The coating was done repetitively multiple times so as to attain a uniform thickness (10 mm) of electrodes on the SS plates.…”

Association of the cathodic operation of Ni(OH) 2 doped water dispersible graphene (WDG) nanocomposite with three different electrolytes (NaHCO 3 , KHCO 3, and NaCO 3) with the help of carbon dioxide (CO 2) electrochemical reduction is presented in this research. Graphene in short time is effectively synthesized and Ni(OH) 2 doped on WDG by electrochemical method, structure, morphology and characterization analysis by X-ray diffraction, scanning electron microscope, transmission electron microscope and Raman spectroscopy. CO 2 is effectively reduced to carbon monoxide (CO) at enhanced situation. Fourier transform infrared spectroscopy, which is used to exanimate integrated Ni(OH) 2-WDG nanocomposite surfaces so as to uncover the carbonate ions and CO during reduction at three different electrolytes. The electron charge resistance of the nanocomposite is investigated by using electrochemical impedance spectroscopy analysis. Analysis of the Ni(OH) 2-WDG nano composite was performed to decouple electrochemical reduction processes of CO 2 to CO at different electrolytes by cyclic voltammetry and linear sweep voltammetry.

“…However, the obvious drawback of the metal‐oxide sensor is that they are typically operated at a high temperature which requires high power consumption resulting in the complex measuring system. Carbon‐based nanomaterials such as graphene, CNTs, single walled nanotubes, multiwalled nanotubes, CNF and NGPs exhibits higher electrical properties . These materials have been exploited as a sensing material for detection of different molecules that act as dopants for the nanomaterials.…”

Herein, one‐step green strategy is demonstrated for the synthesis of multifunctional polymer nanocomposite material using eco‐friendly thiol‐enephotopolymerization reaction at room temperature without use of any crosslinking agents. The greener route of thiol‐ene click reaction results in the formation of extremely high functional groups incorporated crosslinked surface as the thiol groups are reacted with each double bond in the nanograpite network, which is difficult to obtain by any other conventional method. In an attempt to encounter with environmental issues, this facile nanocomposite material can not only detect organic vapor in air but also degrades organic pollutant and microorganisms in water. The response time obtained by thiol‐ene functionalized nanocomposite (TE‐f‐NC) material is recorded as 6 seconds and the recovery is not more than 60 seconds towards formaldehyde vapors. The TE‐f‐NCs for detection of formaldehyde vapor will make a value‐added ultimate product and their commercialization will directly benefit to the society. Moreover, the photocatalytic activity of the obtained TE‐f‐NC material for the degradation of methyl blue (MB) under UV irradiation source was investigated, and found more than 50% of the initial concentration of MB dye degraded within first 3 min using TE‐f‐NC (0.6%) polymer nanocomposite. Along with photocatalytic activity, It is worth pointing out that the hybrid material can be readily used for antimicrobial activity toward various pathogenic microbes depicting the growth inhibition of microorganism by disrupting the cell walls.
