Synthesis of Nickel Oxide (NiO) Nanoparticles and Their Combination with Carbon Paste for Increasing the Electrical Conductivity

Carbon-based materials have been used as electrodes in numerous electro-optical devices in recent years. In some cases, it can be a promising altarnative to those common nobel electrodes because of its advantages such as high thermal and mechanical stability and low cost, which has attracted tremendous amount of attentions. Although carbon has favorable electrical properties, but its combination with low conductive binders limits its performance as electrode or hole transport layer in opto-electronic devices. In this work, using nickel oxide (NiO) nanoparticles in carbon paste has been investigated to affirm that this attractive conductive combination has better electrochemichal performance than the raw material. NiO nanoparticles and NiO-modified carbon paste have been synthesized by sol-gel and mechanical admixing, respectively. The properties of NiO nanoparticles were investigated by XRD and Field Emission Scanning Electron Microscope (FE-SEM) analysis.
