Well-defined metallic nanoporous sphere with single gyroid (SG) structure can be fabricated by simply using self-assembled diblock copolymer with double gyroid (DG) structure as a template for electroless plating. With the control of nucleation and growth process, SG-structured Ni with uniform pore size and high specific surface area was successfully fabricated. Combining the structural and morphological characters of the fabricated nanoporous Ni sphere, it is appealing to be used in a wide variety of applications, such as high-efficiency and well selectivity hydrogenation catalyst with recyclability.
