i want to know how copper is bonded with oxygen/oxygen-hydrogen in copper-oxide/copper-hydroxide nanostructures? what type of bonding exists between them/?
mix bonding covalent and ionic
I reduced CuO and Cu(OH)2 separately into Cu and performed FTIR. I want to make sure no traces of Cu-O or CuO-H bond remains in the final material. How can I analyze the FTIR spectra (attached...
