“…Duan et al synthesized SnS 2 /MWCNTs composite material by hydrothermal method, and its modi ed electrode showed good electrocatalytic activity in the reduction of H 2 O 2 . Nevertheless, relevant data shows that there is room for further improvement in the morphology, structure, speci c surface area and conductivity of the composite material to further improve the sensitivity of the electrode to H 2 O 2 detection [9]. Graphene (G) is a two-dimensional single-layer hexagonal carbon-based nanomaterial, which has the advantages of rapid electron transfer capability, large speci c surface area, good biocompatibility, good chemical stability and environmental stability, etc.…”

In view of the importance of rapid detection of H2O2, a carbon-based three-dimensional conductive network consisting of multiwalled carbon nanotubes (MWCNTs) and reduced graphene oxide (rGO) was introduced into the preparation of SnS2 to obtain SnS2/MWCNTs/rGO modified composite, which was prepared by one-step hydrothermal method. When the mass ratio of MWCNTs and rGO was 1:1, the composite had the best detection effect on H2O2. At this time, SnS2 was uniformly distributed on the surface of tubular MWCNTs and flaky rGO, and MWCNTs were interspersed between layers of rGO. The synergistic effect of the three materials showed a high current response ability for the detection of H2O2. During the range of 0.238 ~ 12.267 mmol·L− 1, the linear equation was Ipc(mA) = -0.029–0.019c(m mol·L− 1), with a sensitivity of 388.28 µA·mmol− 1·L·cm− 2 and a detection limit of 0.236 µmol·L− 1(S/N = 3). Moreover, the prepared modified electrode also had a good selectivity, reproducibility and stability.

Hydrogen peroxide (H2O2), an important representatives of reactive oxygen species, its aberrant expression is related to many diseases including cancers. Therefore, it is very significant to design the reliable method for real-time detection endogenous H2O2. Herein, we prepared a poly (azure I)/crumpled graphene (cGN) modified electrode by electro-polymerization method. Results showed that this electrode presented obvious electrocatalytic effect on the reduction of H2O2. Amperometric method was employed to monitor H2O2, and the amperometric response exhibited a good linear relationship with its concentration in the range of 8.0×10 -6~1 .25×10 -3 mol/L, the detection limit reached to 6.7×10 -7 mol/L (S/N = 3).Furthermore, this modified also displayed the good selectivity, long-term stability and high anti-interference ability. Excitingly, the established method could be successfully used to detect H2O2 in human serum samples, and measured H2O2 secreted from living MCF-7 cells. It could have potential in cancer diagnosis.
