Efficient oxygen evolution reaction catalyzed by low- density Ni-doped Co3O4 nanomaterials derived from metal-embedded graphitic C3N4. Chem Comm 2013;49:7522e4.Zou X, Su J, Silva R, Goswami A, Sathe B R, Asefa T. Efficient oxygen evolution reaction catalyzed by low-density Ni-doped Co3...
For the low Ni-doped Co3O4, X-ray diffraction (XRD) and Raman data show that the Ni ions are successfully incorporated into the Co3O4 lattices. Electrochemical measurements indicate that Co3O4 with low amount of Ni doping possesses remarkably enhanced activity for oxygen evolution reaction (...
The XRD patterns of the pure and Ni-doped Co3O4 powders revealed the formation of single-phase spinel structure, without any impurity phases for all samples. The position and intensity of various absorption bands in the UV–Vis spectra were influenced by the distribution of Co2+ and Ni2+ ...
