Figure 2. Observation of a superoxo intermediate by SEIRAS-ATR on a CoOx(OH)y-Au electrode.Spectra collected on electrodes in contact with 0.1 M solutions of KPi in: (a) D2O, (b) H2O, and (c) H218O at a sample potential of 2.21 V. A spectrum at 1.61 V served as a referencespe...
TCoIII2O4CoIV=O/CoIV(CH3CO2)mono/H2O = DCoIIIO4CoIV=O/CoIV, CoIV(CH3CO2)mono/H2O + e− +0.86 SCoIII2O4CoIII–OOH/CoIII(CH3CO2H)mono = DCoIII2O4CoIV–OOH/CoIII(CH3CO2H)mono + e− +0.12 In situ EPR Oxidation of (1) by one electron results in the well-known param...
0.582 g of Co(NO3)2·6H2O and 0.097 g of Cu(NO3)2·3H2O were dissolved in 40 mL of distilled water with the molar ratios of Co2+/Cu2+=5:1. Then, the above mixture was quickly poured into 40 mL of distilled water containing 1.32 g of 2-methylimidazole (2-MIM)....
On the other hand, the electron-rich dπ orbitals of a FePc sheet not only contain the spin-up orbitals of HOMO-2 and HOMO-3, but also the HOMOs with spin-down. Additionally, contrary to the high-lying dz2 orbital of a CrPc sheet, the electron-deficient dz2 orbital of the FePc ...
The cobalt (II) complexes have been synthesized from the reaction of the cationic entities (3,4-dimethylaniline (1) and histamine (2)) with metallic salt CoCl2⋅6H2O and thiocyanate ion (SCN−) as a ligand in H2O/ethanolic solution and processing by the evaporation crystal growth method ...
(China).For the three-electrode configuration,the as-prepared samples were used as the working electrode,Pt foil and Hg/HgO as the counter electrode and the reference electrode,respectively,and 6 mol L−1KOH was used as the electrolyte.For the two-electrode configuration,the sample and AC ...
after which it was rinsed using DI water, dried with blowing air, and sintered at 200 °C for 30 min in a vacuum evacuated tube furnace. The Pt plating solution consists two separate parts: (1) 0.01 M H2PtCl6·6H2O (Sigma-Aldrich) aqueous solution; (2) 0.3 M NH3(30%,...
(9)CO2+H2O+2e-→CO+2OH- Gaseous CO2 is formed at the interface of the BPM where protons are delivered. Hence, since the catalyst has to be in contact with the membrane in order to suppress the HER, Membrane Electrode Assembly configuration is necessary. This configuration follows the ...
