Preparation of high-quality palladium nanocubes heavily deposited on nitrogen-doped graphene nanocomposites and their application for enhanced electrochemical sensing

High-quality palladium nanocubes (PdNCs) decorated nitrogen-doped graphene (NGE/PdNC) nanocomposites was successfully prepared by using KBr as a capping agent and polyvinyl pyrrolidone as a stabilizer. Further, an enhanced electrochemical sensor for the detection of nitrite was constructed based on a GCE modified with the NGE/PdNC nanocomposites.196
