A simple, novel electrochemical sensing platform based on porous g-C3N4 (PCN) and multi-walled carbon nanotubes (MWCNTs) for the sensitive detection of uric acid (UA) has been proposed. The obtained PCN possessed good biocompatibility and large specific surface area with good dispersion, which was beneficial to electrocatalysis. The introduction of MWCNT as the conducting matrix improved the poor...
In this paper, carbon-coated LiFePO4 nano-hollow spheres (LFP@C HSs) were successfully synthesized using lithium phosphate (Li3PO4) nano-spheres as templates and precursors. The X-ray diffractometer (XRD) demonstrated the crystal structure of LFP@C HSs. The morphology of LFP@C HSs was determined by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Compared with LiFePO4...
This article reported the electrochemical deposition of polyaniline (PANI) on 316-L stainless steel (316LSS) to improve the anti-corrosion performance as PEMFC metal bipolar plates. The results indicate that PANI can increase the corrosion potential of 316LSS by more than 410.57 mV and effectively decrease the corrosion current density by four orders of magnitude in comparison with the uncoated 316LSS...
Herein, we report a simple hydrothermal synthesized V2O5 flake employed as an electrode material for non-enzymatic hydrogen peroxide (H2O2) sensor application. The morphology, structural, and electrochemical properties of the as-prepared material were characterized by using various physicochemical and electrochemical methods viz. scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy...
For the first time, an electrochemical method was proposed for the simultaneous determination of isoniazid (INZ), pyrazinamide (PYZ) and buspirone HCl (BPH) at graphene oxide (GO)/poly-l-arginine (PAG)-modified glassy carbon electrode (GCE). The GO was synthesized by modified Hummer’s method and the surface morphologies of GO and PAG were characterized by scanning electron microscopy (SEM). The simultaneous...
We have described the fabrication of high-performance amperometric sensors derived from graphene oxide–multiwalled carbon nanotube (GO–MWCNT) composite for the sensitive determination of diuron and fenuron. GO–MWCNT composite was prepared by simple solution-based approach, and its formation was confirmed by scanning electron microscopy, transmission electron microscopy and UV-visible spectroscopy...
A simple and sensitive electrochemical method was proposed for the quantitative determination of nonsteroidal anti-inflammatory drug diclofenac (DCF). For the first time, carboxyl-functionalized graphene oxide (GO-COOH)-modified glassy carbon electrode (GCE) was employed for the determination of DCF by cyclic voltammetry (CV) and linear sweep voltammetric (LSV) techniques. The proposed modified electrode...
The electrochemical detection of dopaminergic agonist drug pramipexole dihydrochloride monohydrate (PPX) has been investigated by cyclic voltammetric (CV) and amperometric i–t techniques at functionalized multi-walled carbon nanotubes-modified glassy carbon electrode. For the first time, a sensitive and rapid electrochemical method was developed for the determination of PPX. The surface morphological...
