Characterisation of carbon paste electrodes bulk-modified with surfactants for measurements in nonaqueous media

Vein-Like Ni-BTC@Ni3S4 with Sulfur Vacancy and Ni3+ Fabricated In Situ Etching Vulcanization Strategy for an Electrochemical Sensor of Dopamine

“…Compared with a glassy carbon electrode, a carbon paste electrode (CPE) has the advantages of extremely low background current, low cost, convenient preparation, simple surface renewal process, large potential window, easy modification, simple miniaturization, etc. and has been widely used in electrochemical and electroanalytical chemistry research studies …”

“…and has been widely used in electrochemical and electroanalytical chemistry research studies. 21 Metal−organic frameworks (MOFs) are a novel class of porous organic−inorganic hybrid materials, which are formed by coordination bridges between functional organic ligands and metal ions or ion clusters. 22 Because MOF materials have multiple structural advantages of both organic and inorganic compounds, including controllable surface functional groups, large specific surface area, easily loaded surface-active substances, and pore-rich structures, these are widely applied in catalysis, 23 environmental treatment, 24 biological diagnosis and treatment, 25,26 energy storage and conversion, 27−29 and other fields.…”

Investigation of the photoactivation effect of TiO2 onto carbon-clay paste electrode by cyclic voltammetry analysis

“…Modified electrodes are also used as electrochemical sensors according to their physico-chemical properties [ 2 ]. Carbon is widely used as a base material for the manufacture of conventional electrodes such as glassy carbon (GC), carbon nanotubes (CNT) or multiwall carbon nanotubes (MWCNT) [ [3] , [4] , [5] ]. It is well established as good electrical and thermal conductor with good chemical stability [ 6 ].…”

Electric Field‐Assisted Uptake of Hexavalent Chromium Ions with In Situ Regeneration of Carbon Monolith Adsorbents

“…[8] The introduction of oxygen-containing functional groups such as carboxyl (-COOH), hydroxyl (-OH), and carbonyl (-C=O) on the carbon surface endows the hydrophilic surface, which is beneficial to improve the transportation of metal ions inside carbons. [9] Xie et al modified the surface of carbon nanotubes as an adsorbent to remove Cr(VI) and found that its removal performance was closely related to the surface chemical properties. [10] Bharath et al prepared a nano-composite adsorbent with a high mesoporous structure and a large specific surface area by hydrothermal synthesis, and the maximum electrosorption of Cr(VI) under 1.2 V conditions was 24.5 mg g −1 .…”
