Herein, we aim to suggest a facile method for fabrication of Ni-based nanonetworks via templated electroless plating using mesoporous polymers as templates. With the control of spinodal decomposition for the polymer/crystalline solvent mixture, it is feasible to fabricate mesoporous polystyrene with controlled porosity and pore size as well as its distribution that could serve as a template for templated electroless plating. By taking advantage of the development of reduced Ni from the electroless plating, nanoporous Ni spheres with controlled micrometer-sized particle could be directly acquired, providing the feasibility as heterogeneous catalysts in aimed reactions. With the high specific surface area, the fabricated nanonetwork Ni gave rise to superior performance for catalytic hydrogenation of unsaturated organics and polymers. With the magnetic properties of Ni, catalyst recyclability could be simply achieved by magnetic field. This approach is simple and cost-effective to create nanoporous Ni spheres with high catalytic efficiency and well selectivity for hydrogenation performance.
