“…Therefore, in recent years, there has been a considerable interest in the accurate determination of H 2 O 2 . Many techniques have been employed in the determination of H 2 O 2 , including titrimetry [3], spectrophotometer [4], chemiluminescence [5,6], and electrochemistry [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Among these methods the electrochemical techniques, based on the simplicity, high sensitivity, good stability, low-cost instrumentation and onsite monitoring, have been extensively applied for accurate determination of H 2 O 2 .…”

A nanohybrid composite material was prepared from single-walled carbon nanotubes and silver nanoparticles, and used to fabricate a modified carbon-ceramic electrode. The preparation of the composite is facile and efficient. The nanohybrid composite deposited on the carbon-ceramic electrode was characterized by X-ray diffraction and cyclic voltammetry. The new electrode displays favorable electrocatalytic ability towards hydrogen peroxide (H 2 O 2 ) and can be used to electrocatalytically reduce this species. Under the optimum conditions, the current measured during hydrodynamic amperometry is linearly related to the concentration of H 2 O 2 over the concentration range from 0.01 to 8 mM, with a detection limit of 2×10 −7 M at a signal-to-noise ratio of 3 and sensitivity of 3.23 μA/mM. The electrode exhibits good reproducibility, long-term stability and negligible interference by dopamine, uric acid, and other important biological compounds. The electrode was successfully applied to the determination of H 2 O 2 in honey samples, and the recovery was 101.2%.

“…S-2A, ESI †). 32,33 Moreover, the peak potentials also showed a clear shift. The increase in peak-to-peak separation likely was caused by the nonconductivity of PBI-BA and poor contact between PBI-BA and the gold electrode surface resulting from interference with side chains or distortions in the aromatic backbone.…”

Palladium Nanoparticles Embedded into Graphene Nanosheets: Preparation, Characterization, and Nonenzymatic Electrochemical Detection of H₂O₂

et al. 2014

A novel nonenzymatic H2O2 sensor based on a palladium nanoparticles/graphene (Pd‐NPs/GN) hybrid nanostructures composite film modified glassy carbon electrode (GCE) was reported. The composites of graphene (GN) decorated with Pd nanoparticles have been prepared by simultaneously reducing graphite oxide (GO) and K2PdCl4 in one pot. The Pd‐NPs were intended to enlarge the interplanar spacing of graphene nanosheets and were well dispersed on the surface or completely embedded into few‐layer GN, which maintain their high surface area and prevent GN from aggregating. XPS analysis indicated that the surface Pd atoms are negatively charged, favoring the reduction process of H2O2. Moreover, the Pd‐NPs/GN/GCE could remarkably decrease the overpotential and enhance the electron‐transfer rate due to the good contact between Pd‐NPs and GN sheets, and Pd‐NPs have high catalytical effect for H2O2 reduction. Amperometric measurements allow observation of the electrochemical reduction of H2O2 at 0.5 V (vs. Ag/AgCl). The H2O2 reduction current is linear to its concentration in the range from 1×10−9 to 2×10−3 M, and the detection limit was found to be 2×10−10 M (S/N=3). The as‐prepared nonenzymatic H2O2 sensor exhibits excellent repeatability, selectivity and long‐term stability.
