Electrochemically reduced graphene oxide on gold nanoparticles modified with a polyoxomolybdate film. Highly sensitive non-enzymatic electrochemical detection of H2O2

Green Preparation of Ag-Au Bimetallic Nanoparticles Supported on Graphene with Alginate for Non-Enzymatic Hydrogen Peroxide Detection

“…The Ag-AuNPs/RGO modified glassy carbon electrode (GCE) was prepared as follows. Firstly, the glassy carbon electrode was thoroughly polished with alumina powder and then cleaned with water and ethanol in an ultrasonic bath [ 30 ]. Secondly, 20 μL of the prepared dispersion was dropped onto a pre-treated GCE and dried at room temperature.…”

Facile synthesis of a zeolitic imidazolate framework-8 with reduced graphene oxide hybrid material as an efficient electrocatalyst for nonenzymatic H2O2sensing

“…To obtain various nanocomposites with peroxidase-like bioactivity, noble metal-based materials (Pt, Pd, Ag, Au, etc. ), [8][9][10] carbon-based composites, 11,12 metal oxide-based composites (MnO 2 , 13 ZnO, 14 Sn 3 O 4 , 15 etc. ), MOFs, 15,16 etc., have been proposed and constructed to prepare nonenzymatic H 2 O 2 sensors.…”

ZnO‐CNT Nanostructures as Potential Materials for Non‐Enzymatic H2O2 Sensing

“…Among the recently established methodologies, non‐enzymatic amperometric detection of H 2 O 2 has raised considerable attention owing to its high sensitivity, low cost, ease of operation, and quick response . To improve the electrochemical performance of this method, various redox mediators, especially noble‐metal‐containing substrates, have been used to fabricate chemically modified electrodes for the non‐enzymatic amperometric detection of H 2 O 2 . Recently, we have reported many applications of metal oxide‐decorated sp 2 ‐hybridized carbon nanostructures .…”
