Boosting catalytic performance of ternary FeCoNi yolk-shelled nanoreactors for organic reactions via low-content active metal decoration
(2025) In Science China Technological Sciences 68(7).- Abstract
Nanoreactors have attracted extensive research and attention in the field of catalysis due to their unique surface/interface structures and physicochemical properties. However, conventional nanoreactors have limited catalytic performance due to the confinement of their active components in the “nanochamber”. Herein, low-content active metal (AM, AM = Pd, Cu) decorated yolk-shelled FeCoNiOx (AM/FeCoNiOx) nanoreactors with magnetic recycling properties are synthesized through a simple two-step method. The obtained AM/FeCoNiOx nanospheres are characterized by their distinctive structure and the integration of two kinds of catalytically active components, namely the active FeCoNiOx substrate and...

Nanoreactors have attracted extensive research and attention in the field of catalysis due to their unique surface/interface structures and physicochemical properties. However, conventional nanoreactors have limited catalytic performance due to the confinement of their active components in the “nanochamber”. Herein, low-content active metal (AM, AM = Pd, Cu) decorated yolk-shelled FeCoNiOx (AM/FeCoNiOx) nanoreactors with magnetic recycling properties are synthesized through a simple two-step method. The obtained AM/FeCoNiOx nanospheres are characterized by their distinctive structure and the integration of two kinds of catalytically active components, namely the active FeCoNiOx substrate and the well-dispersed AMs in the whole yolk-shelled substrate. These nanospheres can be utilized as nanoreactors in two types of organic reactions (i.e., reduction and oxidation). During the catalytic reduction of prototypical nitrogen-containing unsaturated organic compounds (e.g., 4-nitrophenol) using sodium borohydride, the Pd/FeCoNiOx nanoreactors demonstrate high activity over Cu/FeCoNiOx and FeCoNiOx counterparts. The catalytic efficiency significantly surpasses that of a variety of magnetic metal-based nanocatalysts reported recently. Meanwhile, the Pd/FeCoNiOx nanoreactors demonstrate remarkable stability and broad-spectrum catalytic capability towards reduction of the other nitrogen-containing unsaturated compounds, including eight substituted nitrobenzenes and two azo dyes. Furthermore, the Pd/FeCoNiOx nanoreactors exhibit exceptional catalytic activity and selectivity in promoting the oxidation of benzyl alcohol. This research provides an effective strategy for the rational design and fabrication of a dual-active-component nanoreactor with simple recycling, which is of practical significance for future sustainable industrial applications.
