Is it possible for Cu spectra to mask the effects of Cu2O and CuO in UV-Vis?

My XRD results yielded points at CuO, Cu2O and Cu. However, my UV-Vis spectra only has one peak at around 580 nm which may or may not correspond to Cu since CuO also has a broad range. Is it...

What do twin peaks in an XRD mean?

I would like to know if there is a reason for these twin peaks in my XRD. The starting material is CuO with hydrazine as the reducing agent. End product is metallic Cu.

What is the reaction between acetic acid and a metal oxide powder?

This metal oxide is Fe(OH)3 and is sparingly soluble in acetic acid. Since this is the case, could a reaction equation be generated? What does acetic acid do to Fe(OH)3? Thanks!

For UV-Vis oxidation studies of Cu nanoparticles w/ gelatin, what is the wavelength shift with increasing time?

Cu nanoparticles coated w/ gelatin will either shift to longer or shorter wavelengths (shown is UV-VIS) as time of storage increases. Where would it most likely shift and why? Thanks!

What are some evidences of direct reduction of CuO to Cu in aqueous solution?

According to an article I've read, reaction path for the formation of Cu from CuO can come from the direct reduction of CuO to Cu or from the dissolution of CuO to Cu2+ ions leading to Cu. In the...
