This 2016 Chinese Chemistry Engram highlights the MOF catalyst for selective hydrogenation. The MOF catalyst is fabricated by sandwiching platinum nanoparticles between an inner core and an outer shell of an MOF with metal nodes of Fe³⁺, Cr³⁺ or both (known as MIL-101), which can convert a range of α, β-unsaturated aldehydes with high efficiency and with significantly enhanced selectivity towards unsaturated alcohols.
