Electrocatalytic hydrogen production on a modified pencil graphite electrode

open access: yesInternational Journal of Hydrogen Energy, 2017
Abstract The development of Polyaniline (PAni)-Chitosan (Chi) and PAni-Chi/Au conducting composite films coated on pencil graphite and used as electrocatalysts for hydrogen production from water is discussed in this study for the first time. The obtained PAni-Chi composite films and PAni-Chi/Au nanostructured composite films were characterized by ...

Aptamer-modified pencil graphite electrodes for the impedimetric determination of ochratoxin A

open access: yesFood Control, 2020
Abstract Ochratoxin A (OTA), a widespread food contaminant, is considered as one of the most hazardous mycotoxins commonly occurring in beer. Herein, we describe a novel impedimetric aptasensor based on Pencil Graphite Electrodes (PGE) for the analysis of OTA. Taking advantage of its affordability and high active surface area, a PGE was modified with
