Nickel Doped Carbon Nitride for Applications in Electrochemical Energy Systems

Abstract

Alkaline fuel cells and supercapacitors have attracted considerable attention over the last decades, mainly because these systems offer the possibility to produce and store energy in a sustainable manner Since the current limitations of these technologies requires the development of highly conductive materials with enhanced stability, this project aims to explore the uses of modified graphitic carbon nitride ( as both OH conductive fillers and pseudocapacitive electrode materials In oder to reach the project’s goal, GCN was fabricated from melamine and then doped with nickel via wet chemistry GCN was also doped with Ni in situ for comparative purposes FTIR and UV vis spectra for both GCN and NiDGCN indicate that these materials were successfully fabricated The results also indicate that the in situ method is more effective at introducing nickel into the GCN’s structure Also, a band gap reduction in Ni doped samples suggests that the presence of metal in the GCN structure, enhances its electrical conductivity
