Magnetically tunable selectivity in methane oxidation enabled by Fe-embedded liquid metal catalysts.

ABSTRACT: As they are liquids at room temperature, gallium-based metal substrates allow catalytic metal atoms to move freely without lattice constraints, thereby facilitating the development of catalysts with reconfigurable structures. Here we design an iron-embedded liquid metal catalyst that enables reversible switching of the aggregation and electron spin of iron atoms by controlling an external magnetic field. This facilitates a reversible conversion of the primary liquid products, methyl hydroperoxide (CH₃OOH) and acetic acid (CH₃COOH), under ambient conditions. The catalyst achieves promising production rates (CH₃OOH, 1,679.6  mmolgFe-1h-1 ; CH₃COOH, 790.5  mmolgFe-1h-1 ) and high selectivities (CH₃OOH, 99.9%; CH₃COOH, 91.7%). I
