Stability and reactivity of copper oxo-clusters in ZSM-5 zeolite for selective methane oxidation to methanol

[Display omitted] •Cu speciation in ZSM-5 zeolite depends on the conditions of thermochemical activation.•Trinuclear [Cu3O3]2+ cationic clusters are preferentially formed in HZSM-5 upon calcination.•Trinuclear Cu-oxo clusters favor the direct methane to methanol oxidation.•Methane activation by binu...
