Synthesis of Pd–Ni/C bimetallic materials and their application in non-enzymatic hydrogen peroxide detection

In this study, carbon based bimetallic materials (Pd-Ni/C) were synthesized by polyol method in order to increase the hydrogen peroxide reduction catalytic activity of Pd using Ni metal. Hydrogen peroxide reduction and sensing properties of the prepared catalysts were measured by electrochemical methods. As a result, we have established that the addition of Ni at different ratios to Pd has a considerable electrocatalytic effect on H₂O₂ reduction. This work provides a simple route for preparation of Pd-Ni catalysts to create a very active and sensible electrochemical sensor for H₂O₂ sensing.
