“…[1] The best catalytic properties are found in metals from the platinum group [2][3], but due to their high prices it is impossible to commercialise production of hydrogen as a common energy carrier. A solution to the problem can be application of alloy or composite catalysers of catalytic properties close to those of the platinum metals though much less expensive [4][5][6][7][8][9][10][11].…”

The article presents results of tests on potentiostatic electrodeposition of ruthenium and Co-Ru alloys.The tests applying the method of cyclic voltammetry with the use of gold disk electrode (RDE) allowed to define a potentials range in which it is possible to obtain ruthenium and its alloys with cobalt from acid chloride electrolytes. The influence of electrodeposition parameters and the electrolyte composition on the composition, morphology and structure of the obtained deposits was determined. Co-Ru alloys underwent XRD tests, an analysis with the XRF method and observations using scanning electron microscopy (SEM).

“…Among the three Ni-P/MoS2 samples, the Ni-MP/MoS2 composite possesses a minimum b value (57 mV/decade) very close to that of the Pt/C sample (52 mV/decade), thereby indicating the promising HER performance of this composite. However, values of b for Ni-LP/MoS2 and Ni-HP/MoS2 composites are 108 and 70 mV/decade, respectively, so their HER performances are lower than that of Ni-MP/MoS2 sample [35]. …”

Molybdenum disulfide (MoS 2 ) is unfavorable for practical application in the hydrogen evolution reaction (HER) process due to its inert basal surface, inferior conductivity, and limited amount of active edge sites. For the purpose of enhancing the HER performance of this catalyst, the HER activity of its basal surface should be increased. Herein, three types of nickel-phosphorus (Ni-P) coatings-namely, low phosphorus (LP), medium phosphorus (MP) and high phosphorus (HP) -were anchored onto the surfaces of MoS 2 nanoparticles via an electroless plating process; thus, three Ni-P/MoS 2 composites (Ni-LP/MoS 2 , Ni-MP/MoS 2 , and Ni-HP/MoS 2 ) were fabricated. Crystal structures, morphologies, chemical components, and HER performances of each in an alkaline solution were characterized. Both Ni-LP/MoS 2 and Ni-MP/MoS 2 showed a crystal nature, while the amorphous feature for Ni-HP/MoS 2 was validated. The three Ni-P/MoS 2 composites exhibited a higher HER activity than the pure MoS 2 . The HER performance of the Ni-MP/MoS 2 composite was more outstanding than those of other two composites, which could be attributed to the presence of metastable nickel phosphides, and the excellent conductivity of Ni-MP coating anchored on the basal surface of MoS 2 .

The kinetics studies of redox reaction between palladium(II) chloride complex ions and potassium formate in acidic aqueous solutions was investigated. It was shown, that the reduction reaction of Pd(II) is selective in respect to Pd(II) complex structure. The kinetic of the process was monitored spectrophotometrically. The influence of chloride ions concentration, Pd(II) initial concentration, reductant concentration, ionic strength as well as the temperature were investigated in respect to the process dynamics. Arrhenius equation parameters were determined and are equal to 65.8 kJ/mol, and A = 1.12×10 11 s -1 .
