Preparation of amorphous copper - chromium oxides

2018121 · Copper-chromium amorphous catalysts have been prepared by a sol-gel method using propylene oxide [28]. Cu ... The low energy peaks of Cu 2p 3/2 at 933.0–934.2 eV are generally attributed to Cu 2+ in octahedral sites, while the high energy peaks at 935.1–935.6 eV correlate with Cu 2 + at the tetrahedral sites [31].
