Nanoceria‐Supported Ru‐Based Nanoparticles as Highly Efficient Catalysts for Hydrolysis of Ethane 1,2‐Diamine Borane

Abstract

Here, the first ever preparation of some series of nanoceria‐supported Ru‐based nanoparticles with different compositions (RuxM100‐x@NC, M: Co, Ni, Pd) and their use as highly active catalysts to liberate hydrogen gas from hydrolysis of ethane 1,2‐diamine borane (EDAB) is reported. For the preparation of totally fifteen RuxM100‐x@NC nanoparticles with different compositions, the related metal cations are first supported on nanoceria surfaces by wet impregnation method in aqueous solution. Then, Ru3+‐M2+‐exchanged nanoceria samples are synchronously reduced during hydrolysis reaction of EDAB to form corresponding RuxM100x@NC nanoparticles meanwhile the formed nanoparticles catalyze the same reaction. RuxM100x@NC nanoparticles are identified by inductively coupled plasma‐optical emission spectroscopy (ICP‐OES), powder X‐ray diffraction (PXRD), transmission electron microscopy (TEM), X‐ray photoelectron spectroscopy (XPS), and BET surface area techniques. They provide quiet high catalytic activities in the hydrolysis reaction of EDAB. Among them, Ru20Pd80@NC nanoparticles are by far the best one up to date with a TOF value of 608.49 min−1 at 25 °C.
