Synthesis of CaCO3/Cu2O/GO Nanocomposite Catalysts for Hydrogen Production from NaBH4 Methanolysis
نویسندگان
چکیده
The synthesis of CaCO3/Cu2O/GO nanocomposites was developed by sol-gel auto-combustion method. analysis structure completed on X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and environmental scanning electron microscopy (ESEM). XRD spectra the matched crystal CaCO3/Cu2O. average size 20 nm for Cu2O 25 CaCO3 nanoparticles. FTIR data showed absorption bands GO. confirmed formation GO sheets. ESEM micrographs displayed spherical nanoparticles dispersed in photoelectron peaks Cu 2p, O 1s, C 3s, Ca 2p. optical revealed an band around 450 nm. calcium content increase led to a decrease energy gap from 2.14 1.5 eV. production hydrogen NaBH4 across methanolysis reaction accelerated nanocomposites. Therefore, these are superior catalytic systems.

Unusually active and sinter-resistant nanocomposite materials were synthesized by combining the high reactivity of nanosized noble metal particles with the excellent hightemperature stability of hexa-aluminates through a simple one-step microemulsion-templated sol-gel synthesis. The novel nanocomposite catalysts were characterized by TEM, XRD, DTA and BET measurements after calcination at tempe...

Producing clean hydrogen from renewable resources will reduce our dependence on using fossil fuels towards a green and sustainable future. Biomass gasification is regarded as a promising technology for hydrogen production. In this work, low cost Ni-based catalyst was applied in a two-stage fixed bed reaction system. Fe was added into Ni-Al catalyst(80mol.% Al) by co-precipitation method with va...
