Porous Co<sub>3</sub>O<sub>4</sub> Nanorods–Reduced Graphene Oxide with Intrinsic Peroxidase-Like Activity and Catalysis in the Degradation of Methylene Blue
A facile two step process was developed
for the synthesis of porous
Co<sub>3</sub>O<sub>4</sub> nanorods–reduced graphene oxide
(PCNG) hybrid materials based on the hydrothermal treatment cobalt
acetate tetrahydrate and graphene oxide in a glycerol–water
mixed solvent, followed by annealing the intermediate of reduced graphene
oxide-supported CoÂ(CO<sub>3</sub>)<sub>0.5</sub>(OH)·0.11H<sub>2</sub>O nanorods in a N<sub>2</sub> atmosphere. The morphology and
microstructure of the composites were examined by X-ray diffraction,
X-ray photoelectron spectroscopy, transmission electron microscopy
and Raman spectroscopy. It is shown that the obtained PCNG have intrinsic
peroxidase-like activity. The PCNG are utilized for the catalytic
degradation of methylene blue. The good catalytic performance of the
composites could be attributed to the synergy between the functions
of porous Co<sub>3</sub>O<sub>4</sub> nanorods and reduced graphene
oxide
