Rh3+ stabilized in KRh@MFI catalyses regioselective hydroformylation

Hydroformylation has been a cornerstone of industrial organometallic catalysis, with regioselectivity being a critical aspect in this process1,2. Present industrial systems use homogeneous Rh-based catalysts with expensive and toxic phosphine-containing ligands, underscoring the need to develop alternative heterogeneous catalysts that could compete with the actual homogeneous ones3. In this direction, atomically dispersed Rh catalysts have been proposed as promising candidates for hydroformylation4,5.

However, achieving high regioselectivity at high conversion is still a big challenge. Here…
