At present, few‐layer graphene is deposited on copper (Cu) foil by chemical vapor deposition (CVD) method. Then, the few‐layer graphenes produced on the Cu foil are coated onto the indium tin oxide (ITO) electrode to investigate their glucose electrooxidation activities. Hexane and hydrogen flow rate and deposition time parameters with CVD method are examined on different Cu foils. These electrodes are characterized by scanning electron microscopy‐energy dispersive X‐ray analysis (SEM‐EDX), X‐ray photoelectron spectroscopy (XPS), and Raman spectroscopy. Furthermore, glucose electrooxidation is examined with cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS) measurements. One could note that the graphene network is clearly visible from SEM images. The deconvoluted XPS spectrum indicates that carbon appeared in the form of non‐oxygenated ring C atoms for few‐layer graphene. The few‐layer graphene structure is confirmed by Raman analysis. Few‐layer graphene/ITO produced at 5 sccm Hexane and 50 sccm hydrogen flow rate and 20 minutes deposition time (G7/ITO) reveals the best electrode activity. The specific activity of G7/ITO electrode is obtained as 6.58 mA cm−2. According to CV, CA, and EIS results, G7/ITO electrode has high electrocatalytic activity, stability, and resistance in comparison with other electrodes.

A Pt nanoparticle modified Pencil Graphite Electrode (PGE) was proposed for the electrocatalytic oxidation and non‐enzymatic determination of H2O2 in Flow Injection Analysis (FIA) system. Platinum nanoparticles (PtNPs) electrochemically deposited on pretreated PGE (p.PGE) surface by recording cyclic voltammograms of 1.0 mM of H2PtCl6 solution in 0.10 M KCl at scan rate of 50 mV s−1 for 30 cycles. Cyclic voltammograms show that the oxidation peak potential of H2O2 shifts from about +700 mV at bare PGE to +50 mV at PtNPs/p.PGE vs. Ag/AgCl /KCl (sat.). It can be concluded that PtNPs/p.PGE exhibits a good electrocatalytic activity towards oxidation of H2O2. Then, FI amperometric analysis of H2O2 was performed under optimized conditions using a new homemade electrochemical flow cell which was constructed for PGE. Linear range was found as 2.5 μM to 750.0 μM H2O2 with a detection limit of 0.73 μM (based on Sb/m of 3). As a result, this study shows the first study on the FI amperometric determination of H2O2 at PtNPs/p.PGE which exhibits a simple, low cost, commercially available, disposable sensor for H2O2 detection. The proposed electrode was successfully applied to determination of H2O2 in real sample.

“…One direction is a nonenzymatic platform which provides very rapid, high sensitivity detection of H 2 O 2 and does not suffer from limitations which are inherently present in biological materials, like in enzyme proteins. These are usually related to the reduced stability when isolated from their natural (biological) environment due to high sensitivity to environmental factors and/or to autocatalytic degradation processes [22][23][24][25]. In addition, the nonenzymatic biosensors are usually simpler and of low cost, and thanks to recent developments their selectivity and sensitivity are increasing in recent publications [24,26].…”

The accurate and sensitive determination of H2O2 is very important in many cases because it is a product of reactions catalysed by several oxidase enzymes in living cells and it is essential in environmental and pharmaceutical analyses. The fabrication of enzyme protein activity based biosensors is a very promising way for this purpose because the function of biological molecules is very specific, sensitive, and selective. Horseradish peroxidase (HRP) is the most commonly used enzyme for H2O2 detection because it can oxidize hydrogen atoms and, for example, xenobiotics in the presence of H2O2. In order to define the limit of detection (LOD) of H2O2 we made calibrations with guaiacol and amplex red (AR), which are hydrogen donors of HRP. The accumulation of the reaction products, tetraguaiacol, and resorufin, respectively, then can be easily detected by absorption or emission (fluorescence) spectroscopy. In our experiments an enzyme electrode was fabricated from ITO (indium tin oxide), functionalized multiwalled carbon nanotubes (f-MWCNTs), and HRP. Although the enzyme activity was smaller by about two orders of magnitude when the enzyme was bound to the f-MWCNTs (ca. 10−2 M H2O2/(M HRP·sec) compared to ca. 2 M H2O2/(M HRP·sec) and 5 M H2O2/(M HRP·sec) with AR and guaiacol in buffer solution), LOD of the H2O2 decomposition was about 6 pM H2O2/sec and 10 pM H2O2/sec in the case of AR and guaiacol, respectively.
