It has been found that multiwalled carbon nanotubes (CS-CNT) can be produced in mass level, simply by pyrolysing mustard oil which was then derivatized with carboxylic acid (CS-CNT (acid)) and ammonia (CS-CNT (base)). A low cost electrode was fabricated on Teflon substrate with three silver wires which was coated with different types of carbon nanotube. A comparative study of electrochemical be...

We explore the use of two-dimensional (2D) MoS2 nanosheets as an electrocatalyst for the Hydrogen Evolution Reaction (HER). Using four commonly employed commercially available carbon based electrode support materials, namely edge plane pyrolytic graphite (EPPG), glassy carbon (GC), boron-doped diamond (BDD) and screen-printed graphite electrodes (SPE), we critically evaluate the reported electr...

The aim of this work is to show how the integration of gold nanoparticles (AuNPs) into multi-wall-carbon-nanotubes (MWCNTs) based screen-printed electrodes and into graphene-based screen-printed electrodes (GPHs) could represent a potential way to further enhance the electrochemical properties of those electrodes based on nanoparticles. Laccase from Trametes versicolor (TvL) was immobilized ove...

A sensitive capsaicin sensor was constructed based on a poly(sodium 4-styrenesulfonate) functionalized graphite modified screen printed electrode (PSS-Grp/SPE) in this study. The PSS-Grp and poly(diallyldimethylammonium chloride) functionalized graphite (PDDA-Grp) were easily synthesized by interacting Grp with PSS and PDDA through sonication, and resulted in negative and with positive charges ...

In this study, we developed a simple high-throughput and cost-effective method for monitoring toxic metal ion in an environmental aqueous sample. Mercury determination with Sequential Injection Analysis system (SIAs) coupled the electrochemical detection on modified screen-printed carbon working electrode (SPCE) is alternative green analysis of mercury ion. The gold film was used as material im...
