In this paper, SnS2/gold nanoparticle (SnS2/GNs) hybrids were synthesized by a
facile solvothermal route. A highly sensitive hydrogen peroxide sensing was then developed
based on the SnS2/GNs hybrid nanomaterials. The obtained porous structure of the
SnS2/GNs hybrid exhibited excellent electrocatalytic activity towards the reduction of
H2O2. The fabricated biosensor exhibits good electrochemical activity for H2O2 with a
comparable linear range from 1 µmol/L to 2785 µmol/L and low detection limit of 0.33
µmol/L. Moreover, the modified electrode displayed good stability and reproducibility.
The current work provides a feasible platform to fabricate a variety of non-enzymatic biosensors.
