Published in 2021 at "Ceramics International"

DOI: 10.1016/j.ceramint.2021.06.186

Abstract: Abstract Here in, a system of Co3O4/CoO catalyst activated with the aid of bisulfite (NaHSO3) was established for the decomposition of methylene blue (MB). The Co3O4/CoO material was designed by a two-step uniform precipitation and… read more here.

Published in 2020 at "Journal of Alloys and Compounds"

DOI: 10.1016/j.jallcom.2020.155030

Abstract: Abstract We report a facile method to synthesise and modify porous Co3O4 nanosheets. The nanosheets are prepared by hydrothermal reaction and calcination, then reduced with an H2/Ar mixed gas at 250 °C within 1 min. The modification… read more here.

Published in 2018 at "New Journal of Chemistry"

DOI: 10.1039/c7nj04638c

Abstract: Cobalt oxide (Co3O4/CoO) nanoparticle-embedded carbon matrix (Co3O4/CoO@carbon) was synthesized by pyrolysis of cobalt-salen complex ([Co(salen)]) followed by hydrothermal treatment. The X-ray diffraction, Raman and Fourier transform infra-red spectroscopies confirmed the presence of Co3O4/CoO in the… read more here.
