Hollow Ni–B amorphous alloy with enhanced catalytic efficiency prepared in …

Abstract. Ni–B nanospheres were synthesized through chemical reduction of nickel ions with borohydride in an emulsion system comprised of cyclohexylamine, polyethylene glycol, and water. With the characterization of X-ray diffraction, selective area electronic diffraction, X-ray photoelectron spectroscopy, and transmission electron microscopy, the resulting hollow Ni–B nanospheres were …
