ZnO is one of the more important materials in semiconductor applications due to the specific electronic structure of the metal atoms characterized by a filled valence band, and an empty conduction band. ZnO also has also a great potential in photocatalysis and energy storage applications because of its physical and chemical stability, high oxidative capacity, low cost and readily availability. novella new synthetic strategy enables dispersion of zinc oxide (ZnO) particles in porous carbon structures, which could enhance the electrical properties of ZnO NPs. Octylamine (OA)-capped ZnO and poly(styrene-co-acrylonitrile) (PSAN)-capped ZnO nanoparticles (NPs) were synthesized by a thermal decomposition and “ligand exchange” method and ZnO-carbon nanocomposites were synthesized through pyrolysis of a mixture of OA-capped ZnO NPs/PSAN and PSAN-capped ZnO NPs. The resulting ZnO-carbon materials exhibit high capacitance and good catalytic efficiency in a methylene blue degradation test, when compared to pure ZnO. Consequently the ZnO-carbon materials show promise in supercapacitor and water pollution treatment applications.
