NiMo was
electrodeposited on Ti foil (thickness 0.025 mm, Goodfellow, ≥99.6+%)
in a two-electrode cell according to the procedure described by Fan
et al.47 (link) with certain modifications. The
molarities of NiSO4·6H2O (Sigma-Aldrich),
Na2MoO4·2H2O (Sigma-Aldrich),
and Na3C6H5O7·2H2O (Sigma-Aldrich) were kept the same, but the electrodeposition
was carried out stepwise under potentiostatic control at 2.85 V. The
Ti foil substrate served as the cathode electrode, and a Ni foam was
used as sacrificial anode with the nominal area for both electrodes
being 4 cm2. Four electrodeposition steps are discerned
with the main difference that in the two first steps the solution
was not stirred, while in the following two steps the solution was
stirred. Each step was applied successively and lasted for 60 s, and
the current ranged between 33 and 40 mA cm–2. This
procedure gave visually the most homogeneous coatings, as well as
optimized performance of the NiMo cathodes.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
