A study of the catalysis of cobalt hydroxide towards the oxygen reduction in alkaline media

Single-site and nanosized Fe–Co electrocatalysts for oxygen reduction: Synthesis, characterization and catalytic performance

“…Since none of the Fe and Co catalyst is able to oxidize ethanol in either half cells or monoplanar DAFCs [61][62][63][64][65][66], the current decay at high ethanol concentration may be ascribed to competitive adsorption of oxygen and ethanol on the catalytically active sites. In contrast, the ORR activity of Pt/C and Pt/Vulcan decreased dramatically just upon adding 1 wt% ethanol to the oxygen saturated solution [23,67], which is consistent with the well known ability of Pt-based catalysts to oxidize alcohols [68].…”

Kinetic Study of the Oxygen Reduction Reaction on α-Ni(OH)2and α-Ni(OH)2Supported on Graphene Oxide

“…9,11,14 However, as stated above, the activity of the β-Ni(OH) 2 catalyst is quite low. The order of reaction with respect to O 2 is ∼1 for MnO x and CoO x , 9-10 similar to that reported for precious metal catalysts.…”

“…In these works, oxides (or hydroxides) of manganese and cobalt have received the majority of the attention with particularly promising results demonstrated for CoO/carbon nanotube hybrids, carbon-supported MnO x /C, and a Co 3 O 4 /N-doped graphene hybrid. [8][9][10][11] In contrast to manganese and cobalt, comparatively little work has been directed toward evaluating the different phases of nickel oxide or hydroxide as catalysts for the oxygen reduction reaction. Such work may uncover new oxygen reduction reaction catalysts, and may also clarify the mechanism by which doping with nickel hydroxide enhances activity and durability of MnO x catalysts.…”

The influence of KOH concentration, oxygen partial pressure and temperature on the oxygen reduction reaction at Pt electrodes

“…Structure-activity relationships have been derived for catalysts composed of either bulk single metals [16,17], or bimetallic alloys [14,15]. ORR mainly proceeds via a 4-electron pathway on Ag and Pt electrode [18,19], while 2-electron and 1-electron processes occur on the glassy carbon electrode [20]. Apart from the electrode materials, ORR kinetics has been found to be very sensitive to the electrolyte [21][22][23].…”
