![]() ![]() These results demonstrate that new MWCNT electrocatalytic systems are potential substitutes for platinum or other metal-based cathode materials in proton conducting membrane fuel cells. Rotating disk electrode and rotating ring disk electrode measurements revealed the mechanism to be a direct four-proton and four-electron redn. Generally, chemical functionalization degrades the conjugated structure of the nanotubes since they tend to modify the hybridization of sp 2 to sp 3 and. The electrodes are easily fabricated by a drop-casting vacuum drying procedure. Carbon nanotubes (CNTs) have been proposed and actively explored as multipurpose innovative carriers for drug delivery and diagnostic applications. These results demonstrate the advantages of systems of MWCNTs covalently linked to electrocatalytic mols. rates achieved are more than one order of magnitude higher than previously reported values for similar Co-porphyrin catalysts. Study of functionalized single-walled carbon nanotubes (SWCNTs) and their potential use as sensors for biomolecules by Near Infrared (NIR) Fluorescence. Ethylenediamine-functionalized multiwalled carbon nanotubes (EDA-CNTs) delivered the best HER activity holding a low-onset overpotential of 150 mV, a Tafel slope of 116 mV dec1, and a. With low catalyst loading, the oxygen redn. Six kinds of functionalized multiwalled carbon nanotubes (FCNTs) with different functional moieties were utilized as metal-free electrocatalysts towards the hydrogen evolution reaction for the first time. in acidic media (pH = 0.0-5.0) at room temp. The MWCNT-Co-porphyrin compns., mixed with Nafion, displayed excellent catalytic performance for oxygen redn. by covalently grafting a Co(II) porphyrin to functionalized multiwalled carbon nanotubes (MWCNTs) via zwitterionic functionalization of the CNT sidewalls followed by a SN2 substitution reaction. While the functionalization of nanoparticles such as Multi-walled carbon nanotubes (CNT) allows us to house the adsorption properties of atoms or molecules on the walls of CNT, therefore, in this research we performed the functionalization of carbon nanotubes with kinetin which is a plant hormone that promotes cell division, growth, and. Studies found that carboxylic group and hydroxyapatite enhanced the mechanical and bio-properties of the material. Zhang, W, Shaikh, AU, Tsui, EY, Swager, TMĬobalt porphyrin functionalized carbon nanotube ca, fuel cell cobalt porphyrin functionalized carbon nĬarbon nanotube (CNT) compns. explored functionalized multiwalled carbon nanotubes with the carboxylic groups and an anodic procedure was used to obtain TiO 2 nanotubes. Cobalt Porphyrin Functionalized Carbon Nanotubes for Oxygen Reduction ![]()
