Paper Title
Chromia and Alumina Supported and Unsupported NANO Particles As Non-Noblepotential Candidates for Co Oxidation

Abstract
Herein, we report the synthesis of chromium oxide nanoparticles, α -Cr2O3 NPs, and aluminum oxide nanoparticlesγ- Al2O3NPs, followed by full characterization via XRD, SEM, XPS, N2sorptiometry and TEM. The results revealed that the α -Cr2O3 NPs are cubic in shape while γ- Al2O3 NPs are semispherical with small particle sizes and relatively high surface areas. Also the synthesized nanoparticles were supported on reduced graphene oxide as shown in Fig. 1. The synthesized nanocatalysts will be tested for co oxidation measurements which may provide effective and economic solutions to overcome one of the major environmental threats.
