N-doped bamboo-like CNTs combined with CoFe–CoFe2O4 as a highly efficient electrocatalyst towards oxygen evolution

Active sites and optimization of mixed copper-cobalt oxide anodes for anion exchange membrane water electrolysis

“…Bare Carbon Paper similar to the best values obtained in other equivalent studies in the literature [56,58,59].…”

Preparation of Bimetallic CoFe@CSC-700 Carbonated Microspheres and Activated Peroxymonosulfate for Degradation of Levofloxacin

“…Firstly, the CoFe@CSC-700 consists of C, O, N, Fe, and Co elements, as seen in the survey spectrum (Figure 3a), which was compatible with the EDX results. Figure 3b shows the high-resolution C1s energy spectra obtained from the test, which corresponded to the C-C characteristic peak at 284.8 eV binding energy, the C-N bond characteristic peak at 285.7 eV binding energy, the C=O bond characteristic peak at 288.1 eV, and the O-C=O bond characteristic peak at 290.0 eV, as shown in the past literature [29], whereas the π-π vibration of carbon corresponds to the π-π vibration at 291.6 eV. The incorporation of C-N bonds indicated that nitrogen had been successfully doped into the carbon molecular structure, constituting a crucial facet of the redox reaction process [30].…”

Research progress of spinel CoFe2O4 as an electrocatalyst for the oxygen evolution reaction

“…However, the high cost and defects of these materials have limited their large number of commercial applications. [18][19][20] It makes sense to develop nonnoble metal electrocatalysts that are highly efficient and inexpensive. In recent years, researchers have been dedicated to investigating high-performing non-precious OER catalysts, including carbon materials and transition metal compounds, such as oxides, carbides, phosphides, hydroxides, etc.…”
