The crystal structure of copper perchlorate hexahydrate, Cu(ClO4)2 • 6 H20 The Cu-(H2O)6 octahedron with a mean Cu–O length of 2.18 and the ClO4 tetrahedron with a mean Cl–O length of 1.48 are only slightly deformed from the ideal structures. The hydrogen bonds which link the wate...
-Copper does not react with hydrochloric acid. As a metal acid reaction leads to redox reaction. Copper has a higher reduction potential than hydrogen, so it does not react with mineral acids like hydrochloric acid or sulphuric acid. -Copper oxide is a metal oxide and it...
A novel method is proposed for the chlorination of a silicon compound having, in a molecule, at least one hydrogen atom directly bonded to the silicon atom. The method comprises the step of reacting the starting silicon compound with anhydrous copper (II) chloride as a chlorinating agent in ...

One of the present great challenges is finding nonprecious materials characterized by efficient electrocatalytic behavior in order to substitute the expensive platinum-based materials for the purpose of hydrogen evolution reactions (HERs). In this study, ZIF-67 and ZIF-67 were used as precursors in...
Hydrogen peroxide concentration entering the catalyst tube varied between 0.005 and 0.03 mol/m3, which scales inversely with flow rate of helium through the bubbler. Each catalyst size was tested as a campaign, working through the range of flow conditions, prior to switching to a different ...
with a high peak power density of 577 mW cm−2(18 times as high as the Ni/C anode) and a stability of more than 150 h (a degradation rate slower by 7 times than the Ni/C anode). The spectroscopies demonstrate that the alloy effect from Cu weakens the hydrogen binding, and...
