Rationally designing mixed Cu–(μ-O)–M (M = Cu, Ag, Zn, Au) centers over zeolite materials with high catalytic activity towards methane activation

The direct conversion of methane to methanol on [Cu(μ-O)M]²⁺ (M = Cu, Ag, Zn, Au) bimetal centers in ZSM-5 zeolite is investigated using periodic DFT for the first time.

Effect of Brønsted acid sites on the direct conversion of methane into methanol over copper-exchanged mordenite

The direct conversion of methane into methanol was studied in a stepwise process over copper-exchanged mordenite.

DFT exploration of active site motifs in methane hydroxylation by Ni-ZSM-5 zeolite

DFT calculations suggest [Ni₂(μ-O)₂]²⁺ and [Ni₃(μ-O)₃]²⁺ species as two possible active sites in methane hydroxylation by Ni-ZSM-5 zeolite. Both of them are predicted to activate methane and desorb the formed methanol with low activation and desorption energies.
