The excellent activity could be ascribed to the large electrochemical surface area provided by the carbon nanoarray, as well as the supersmall size (≈10 nm) of α-Ni(OH)2 which possess a large number of active sites for the reaction. In addition, the phase evolution of α-Ni(OH)2 ...
Nickel is particularly attractive as a receptor element due to its low price, abundance and excellent catalytic HCHO oxidation performance in alkaline media, based on the formation of an active redox Ni(OH)2/NiOOH couple [[8], [9], [10]]. As a result, Ni-nanoparticle-based electrodes, ...
(OH)2, respectively, coming from the surface oxidation. The Ni (0) peaks of NiCuCr/C, NiCu/C, and NiCr/C show a positive shift (~0.8 eV) compared with Ni/C, indicating the transferred electrons from Ni. Supplementary Fig.6shows the high-resolution Cu 2pspectra of NiCuCr/C and ...
The number of those proton vacancies increases when the crystallite size decreases or when the ratio of co-precipitated cobalt increases. Proton vacancies shift the oxidation potential of β-Ni(OH) 2 towards less anodic values and, therefore, improve the chargeability and the electrochemical ...
The forward peak appeared at 0.33 V is attributed to the formation of NiOOH by oxidation of NiO, while the reverse peak observed at 0.27 V is due to the reduction of NiOOH to Ni(OH)2. It is noted that the peak potential separation is 60 mV which is close to the value ...
peaks of Ni2+/Ni3+ remained almost unchanged during the EOR process on Ni/MnO2, whereas those of α-Ni(OH)2 decreased with the number of cycles, and ii) the EOR current relative to the current due to the oxidation of Ni2+ was quite larger in Ni/MnO2 than that in α-Ni(OH)2. ...
