Enhanced electrochemical sensing of nitroaromatic compounds based on hydroxyl modified carbon submicroparticles

“…The areas enclosed by CVs are in the order of OCNPs/GC > HCSs/GC % CNPs/GC > GC, which is in accord with the order of background currents in above LSV test. It is well known that carbon materials with high specific surface area (SSA) and abundant surface groups facilitate to providing large interface for detection of target molecules on electrochemical sensor [15,16], but causing undesired higher background current and noise that from double-layer capacity [46]. As compared with the OCNPs or CNPs in size of nanometers, HCSs in size of submicrometers possess smaller SSA and exhibit relatively small background current in the absence of NB.…”

“…Carbon materials such as graphenes [11][12][13][14], carbon nanotubes [15] and nanoporous carbons [16][17][18] are fascinating candidates for electrochemical determination of NACs due to their unique structures and excellent properties, such as large surface area, superior electrical conductivity, and ease of functionalization.…”

Synthesis of Co‐doped CeO2 nanorods modified glassy carbon electrode for electrochemical detection of nitrobenzene

“…Nitrobenzene (NB), a high priority pollutant in wastewater that originates from industries and its carcinogenicity effects motivate researchers exploit methods for the detection of NB . Wei et al, has reported the synthesis of CeO 2 nanoparticles modified glassy carbon (GC) electrode and its detection towards uric acid and ascorbic acid .…”
