In situ activation of a Ni catalyst with Mo ion for hydrogen evolution reaction in alkaline solution
In this study Ni catalyst have been activated during hydrogen evolution reaction (HER) by adding Mo ions into the alkaline electrolyte. After dissolving different amounts of ammonium molybdate in the 1M NaOH as electrolyte, Ni catalyst was used as cathode for HER. Afterwards a comparison between hydrogen overpotential measured in Ni catalyst with and without in situ activation has been made; th...
متن کاملEffect of temperature on kinetics of the hydrogen evolution reaction on Ni-P-C cathodes in alkaline solution
The kinetics of hydrogen evolution reaction (HER) was studied in 1M NaOH at various temperatures (298 to 358 K) on Ni-P-C (composite electrodes. The electrochemical efficiency of the electrodes has been evaluated on the basis of electrochemical data obtained from the steady-state polarization Tafel curves, electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) in 1M NaOH solut...
متن کاملNickel cobalt phosphides quasi-hollow nanocubes as an efficient electrocatalyst for hydrogen evolution in alkaline solution.
A template-engaged strategy is used to synthesize nanostructured metal phosphides with different compositions. Among the as-synthesized metal phosphides, nickel cobalt phosphides quasi-hollow nanocubes exhibit the best electrocatalytic activity for hydrogen evolution reaction in terms of lower overpotential and smaller Tafel slope in alkaline solution.

متن کاملHydrogen Atom-formaldehyde Reaction
where H-H-C and H-D-C are weak bonds and make a negligible contribution, leads to a value of -2 kcal. Therefore, E5-E2=1 kcal compared with the experimental value of 1.0 kcal. The preexponential factor for this pair of isotopic reactions can be calculated from the difference in the entropies of activation. Using the same loose complex as above and applying the expression derived by Bigeleisens ...
