Abstract The raw attapulgite mineral was purified into nano-fibers and the nano-purification of attapulgite was modified by electroless plating a continuous layer of nickel on it.The effects of pre-treatment on the electroless nickel plating of attapulgite were analyzed by transmission electron microscopy(TEM) and X-ray diffraction(XRD).The results showed that by adding activated sites before electroless plating,the surface of attapulgites can be coated with layer of nickel.And it is difficult to gain continuous uniform distribution elcetroless plating layer for attapulgites because of its large proportion of longitudinal axis length and diameter,and its weak reaction capacity.Therefore,further optimization way of pre-treatment(especially coarsening and activation) and process parameters were needed to be successful coated with complete layers of nickel on attapulgites.
