CuCl2 immobilized on amino-functionalized MCM-41 and MCM-48 and their catalytic performance toward the vapor-phase oxy-carbonylation of methanol to dimethylcarbonate

Removal of elemental mercury from flue gas by recyclable CuCl 2 modified magnetospheres catalyst from fly ash. Part 1. Catalyst characterization and performance evaluation

“…The binding energies of 934.8 eV and 955.1 eV corresponding to Cu 2p3/2 and Cu 2p1/2 is assigned to Cu 2+ in CuCl 2 [30], along with the satellite spike at 938.3-945.8 eV assignable to Cu 2+ [37]. Little Cu + in CuCl was also observed with the binging energies at 932.4 and 952.2 eV, which are attributable to Cu 2p3/2 and Cu 2p1/2 levels of Cu + species [30,37]. In this work, Cu + species were also observed for the other catalysts with different Cu loading.…”

High catalytic activity of CuY catalysts prepared by high temperature anhydrous interaction for the oxidative carbonylation of methanol

“…For XPS spectra of Cu2p, it is generally known that the overlapping peak from 930.0 eV to 940.0 eV can be resolved into two 2p 3/2 peaks at 932.4 eV and 934.9 eV attributed to Cu + and Cu 2+ respectively. [35][36][37][38] By means of XPS-peak-differentiating analysis, the relative content of copper species was determined and the results were listed in Table 1. As shown in Table 1, the total copper content and relative contents of Cu 2+ and Cu + vary with different activation atmosphere.…”

Physicochemical Properties of CuO2 (acac)2 Supported on Functionalized MCM41 Containing Thiourea Ligand

“…Then, the mixture was refluxed for 6 hours. The mixture was filtered, washed, dried at room temperature and stored in desiccators [8].…”
