Remarkably and stable catalytic activity in reduction of 4-nitrophenol by sodium sesquicarbonate-supporting FeO@Pt.

Reasonable design of bimetallic nanomaterials with support is beneficial to improve catalytic performance. This work reports a new kind of sodium sesquicarbonate-supporting FeO@Pt etching FeO@Pt@SiO, which exhibits highly efficient and stable catalytic reduction performance towards 4-NP. Sodium sesquicarbonate-supporting FeO@Pt has an interconnected one-dimensional network structure that provides sufficient channels for mass transfer. At the same time, a large amount of FeO@Pt is exposed on its surface, which hinders the aggregation of pt clusters and FeO nanoparticles, and facilitates the direct contact of FeO@Pt reaction sites with reactant molecules, thus improving the catalytic rate of 4-NP reduction reaction. Moreover, the introduction of non-metallic Fe can not only reduce the consumption of precious metal Pt, but also improve the catalytic efficiency due to the synergistic effect. This study opens up a new avenue to develop robust catalysts for heterogeneous catalytic reactions.
