Preparation of magnetic Ni/wollastonite and zeolite P/Ni/wollastonite composite fibers

► Core-shell Ni/wollastonite fibers were fabricated by electroless plating. ► Zeolite P/Ni/wollastonite fibers were prepared by in situ hydrothermal method. ► Zeolite P/Ni/wollastonite fibers exhibited good magnetic properties. ► Zeolite P/Ni/wollastonite fibers showed good sorption properties for Cu2+ ions.
