Abstract:-
Novelty/Improvement:
Objectives:
For the first time “Honey” was used a source for production of CMK-3 Carbon and utilized for selective determination of DA,CY,AA & PA
To synthesize CMK-3 Carbon and study its application as modified electrode in three electrode cyclic voltammetry.The modified electrode using CMK-3 Carbon is used for selective determination of Dopamine (DA), L-Cysteine (CY), Ascorbic acid (AA) & Paracetamol(PA).
Keywords: CMK-3, Modified carbon Electrode, Cyclic Voltammetry, electro catalytic activity. 1. Introduction:
Findings:
In recent research several carbon-based materials including the carbon fibre,boron doped diamond film, exfoliated graphite etc., have been explored for the electrochemical detection and separation of Dopamine(DA), Ascorbic Acid(AA) ,L-Cysteine(CY) & Paracetamol(PA) [1,2].Presently the Nitrogen- doped carbon as received increasing attention as Oxygen Reducing
The mesoporous carbon CMK-3 was synthesized using SBA15 as the hard template and honey as the natural carbon source. The SBA-15 was synthesized using Tetra Ethyl Ortho Silicate (TEOS) as the silica source & Pluronic (P123) as the structure –directing agent. The CMK3 thus obtained was systematically characterized by XRD, BET, SEM and TEM. The low-angle XRD patterns of ordered mesoporous silica (SBA-15) and carbon (CMK-3) reveal that the diffraction pattern of the mesoporous carbon is replicated the parent structure of SBA-15. The TEM and SEM results showed that the hexagonal symmetric pore structures of CMK-3 were highly ordered and the surface area was found to be 587.8 m2/g. The electrocatalytic behaviors of ordered mesoporous carbon (OMC) modified electrode towards the oxidation of dopamine (DA) and ascorbic acid (AA) L-Cysteine (Cy) and reduction of Paracetamol (Acetaminophen)(PA) were studied by cyclic voltammetry. The OMC modified electrode showed high electrocatalytic activities toward the oxidation of DA and AA, CY and reduction of paracetamol and resolved their voltammetric responses into well-defined peaks. Thus the modified carbon electrode can be used for the selective determination of these types of drug components.

Reaction(ORR) catalyst.Nitrogen-doped grapheme [3],carbon spheres[4] ordered mesoporous graphic arrays[5] carbon nano tubes[6] and ordered mesoporous carbon have been reported as the ORR catalyst.In the present investigation,we have developed a mesoporous carbon using Honey as the Carbon source.Natural Honey is a polysaccharide contains a content of 80-85 % Carbohydrates,15-17% Water,0.3% Proteins,0.2% ashes and minor quantities of amino acids and Vitamins that supply supply carbon and nitrogen atoms[7].Our result showed that prepared N-OMC s having nitrogen satisfactory electro catalytic activity.In this report,we present the electrochemical properties of the ordered mesoporous carbons which were prepared by using the Mesoporous Silica materials SBA-15 as the template and Honey as the Carbon Source. Different types of Carbon based electrodes have emerged over the last few years ,significantly widening the scope and improving the sensitivity of electrochemical sensors.Recent studies showed that Omc has attractive |
