| Abstract
| - The supported nickel boride (Ni−B/MgO) catalysts have been synthesized using electroless plating method.The effects of reaction parameters including the molar ratios of the starting materials, pH value of the platingsolution, and the additives have been systematically studied. The catalysts have been characterized by varioustechniques such as inductively coupled plasma atomic emission spectrometry, high-resolution transmissionelectron microscopy, scanning electron microscopy, and chemisorption of hydrogen. The hydrogenatingproperties were evaluated using the liquid-phase hydrogenation of sulfolene and acetophenone. We foundthat (1) the size, compositions, and load of porous Ni−B nanoparticles depended on the starting ratio ofethylenediamine/Ni2+ and pH value; (2) the addition of stabilizer to plating solution resulted in changingfrom a porous Ni−B particle to a solid one, (3) the surface properties of supported Ni−B catalysts dependedon their sizes, loading, and compositions, and (4) the hydrogenation activity depended on the surfaceconcentrations of nickel.
