CoFe-LDHs catalyzed oxidation cleavage of terminal alkenes to aldehydes or ketones†
Abstract
Cobalt–iron layered double hydroxides (CoFe-LDHs) with adjustable Co/Fe ratios were synthesized for the alkene oxidative cleavage to carbonyls under 1 atm O2. Structural analyses reveal that coexisting Co2+/Co3+ species enhance catalytic activity, while synergistic Co–Fe interactions in the LDH lattice promote electron transfer, achieving superior conversion and selectivity compared to monometallic catalysts.
