In-situ etching of stainless steel: NiFe2O4 octahedral nanoparticles for efficient electrocatalytic oxygen evolution reaction

Low‐cost Trimetallic Ni‐Fe‐Mn Oxides/(Oxy)hydroxides Nanosheets Array for Efficient Oxygen Evolution Reaction

“…It is found that the leaching amount of Fe coincides with the rise of overpotential for NiFeMnO x H y ‐SSP and NiFeO x H y ‐SSP. It has been reported that FeOOH can be dissolved into the electrolyte forming FeO 4 2− during electrolysis process under alkaline condition [72–74] . We thus attribute the difference of stability to the leaching amount of Fe from NiFeMnO x H y ‐SSP and NiFeO x H y ‐SSP.…”

“…It has been reported that FeOOH can be dissolved into the electrolyte forming FeO 4 2À during electrolysis process under alkaline condition. [72][73][74] We thus attribute the difference of stability to the leaching amount of Fe from NiFeMnO x H y -SSP and NiFeO x H y -SSP. It is worth of noting that the leach of Mn for NiFeMnO x H y -SSP was observed as well (Table S7, Figure S13), but it has neglect influence on the stability.…”

NaBH4 reduced Mn-doped cobalt tetroxide R-MnxCo3−xO4 catalysts with plentiful oxygen vacancies for HCHO oxidation at low temperature

“…As a common spinel structured oxide, Co 3 O 4 has attracted widespread attention in the field of catalytic oxidation [9][10][11] due to its environmental friendliness, high cost-effectiveness, and relatively good catalytic performance. [12][13][14][15] Co 3 O 4 has been widely reported for catalytic oxidation of VOCs such as HCHO, [16][17][18] CO, 19 CH 4 , 20 C 2 H 4 , 21 C 3 H 8 22 and toluene.…”

Dual Modification of Stainless Steel by Small Molecule Oxalic Acid for Oxygen Evolution Reaction

“…Therefore, many nonprecious metal-based electrocatalysts (mainly transition metals) have been extensively investigated, including transition metal sulfides, phosphides, carbides, nitrides, etc. − In addition, materials such as layered double hydroxides (LDHs) and metal–organic frameworks (MOFs) also have been widely studied because of their large specific surface area, high design flexibility, and simple synthesis methods. , With excellent electrocatalytic properties, NiFe-based composites are highly applicable among the reported transition metal-based electrocatalysts. − With low costs, superior corrosion resistance, and mechanical properties, stainless steel (SS) materials (mainly composed of transition metals such as Fe, Ni, Cr, and Mn) are widely used in various industrial scenarios . The presence of nickel and iron provides good intrinsic catalytic activity for SS, which has excellent potential in electrocatalysis. − …”
