摘要

在1atm O2条件下，合成了Co/Fe比可调的钴铁层状双氢氧化物（CoFe-LDHs），用于烯烃氧化裂解羰基。结构分析表明，共存的Co2+/Co3+增强了催化活性，而LDH晶格中Co-Fe的协同相互作用促进了电子转移，与单金属催化剂相比，具有更好的转化和选择性。

CoFe-LDHs catalyzed oxidation cleavage of terminal alkenes to aldehydes or ketones†

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.
