The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 13395-16-9 is helpful to your research. Synthetic Route of 13395-16-9

Synthetic Route of 13395-16-9, One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time.Mentioned the application of 13395-16-9.

Mesoporous Hollow Cu-Ni Alloy Nanocage from Core-Shell Cu@Ni Nanocube for Efficient Hydrogen Evolution Reaction

We have created a facial self-templated method to synthesize three distinct nanostructures, including the unique edge-cut Cu@Ni nanocubes, edge-notched Cu@Ni nanocubes, and mesoporous Cu-Ni nanocages by selective wet chemical etching method. Moreover, in the synthesis process, the corners of edge-cut Cu@Ni nanocubes and mesoporous Cu-Ni nanocages can be etched to produce the highly catalytically active (111) facets. Impressively, compared to edge-notched Cu@Ni nanocubes and edge-cut Cu@Ni nanocubes, the Cu-Ni nanocages exhibit higher electrocatalytic activity in the hydrogen evolution reaction (HER) under alkaline conditions. When obtained overpotential is 140 mV, the current density can reach 10 mA cm-2 meanwhile, the corresponding Tafel slope is 79 mV dec-1. Moreover, from the calculation results of density functional theory (DFT), it can be found that the reason why the activity of pure Ni is lower than that of Cu-Ni alloy is that the adsorption energy of the intermediate state (adsorbed H?) is too strong. Meanwhile the Gibbs free-energy (|DeltaGH?|) of (111) facets is smaller than that of (100) facets, which brings more active sites or adsorbs more hydrogen.
