Abstract

Phis study reports the development of a novel Cr1-xNaxO3 catalyst using a simple cost-effective method for hydrogen production from NaBH4 methanolysis. The properties of the nanocomposites were investigated by employing XRD, FTIR, SEM and XPS characterization techniques. The XRD diffraction peaks confirmed the rhombohedral crystal structure of Cr1.xNaxO3 nanoparticles. The average crystal size of these nanoparticles was found to be ranging from 25.0 to 20 nm. FTIR analysis showed the characteristic absorption bands of Cr1.xNaxO3 nanoparticles. The SEM images of Cr2O3 and Cr1.7Na0.3O3 demonstrated that the nanoparticles are irregular in shape, while Cr1.4Na0.6O3 has a porous surface texture. XPS spectra of Cr2O3, Cr1.7Na0.3O3 and Cr1.4Na0.6O3 confirmed the presence of chromium, oxygen, and sodium in the samples. The optical band gaps of Cr2O3 Cr1.7Na0.3O3 and Cr1.4Na0.6O3 …
