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 degrees C.
