Abstract A novel sensor based on carbon black‐gold nanoparticle nanocomposite modified screen‐printed electrode (CB‐AuNPs/SPE) for the detection of As(III) has been developed. The was prepared modifying SPE with CB and AuNPs by a drop casting automatable deposition. detected CB‐AuNPs/SPE using anodic stripping voltammetry, high sensitivity (673±6 µA µM −1 cm −2 ) reaching LOD 0.4 ppb. Finally, applied to trace analysis in drinking water, obtaining satisfactory recovery values (99±9 %).
Abstract Living photovoltaics represent a growing class of microbial devices that are based on whole cell–electrode interactions. The limited charge transfer at the interface represents significant bottleneck in realizing an efficient technology. This study focuses development poly(3,4‐ethylenedioxythiophene) (PEDOT)‐based electrodes electrosynthesized presence sodium dodecyl sulphate (SDS) dopant. Potentiodynamic and potentiostatic electrochemical techniques, as well scanning electron...
The paper reports on the feasibility of obtaining graphene nanomaterials with remarkable structural and chemical features from shungite rocks. investigation composition modifications induced in pristine, natural C-containing mineraloid by a specifically designed physicochemical purification treatment is performed combined use several techniques (scanning electron microscopy, high resolution transmission X-ray diffraction, Raman photoelectron spectroscopies). adopted material processing...
We report here on soft-template electropolymerizations of polypyrrole (Ppy)-based nanocomposites triggered by graphene platelets (GP) from shungite (SH) rocks. A properly designed procedure for an efficient extraction SH powders is established to produce remarkable materials in a low oxidation state and with high electrical conductivity (1490 S cm-1). By using positively negatively charged templating surfactants the role played units electropolymerization reactions pointed out SEM, EDX, TEM,...
