Herein we report a novel strategy involving the hybridization of nanoporous NiO flakes with graphene oxide (GO) sheets. The as-prepared flake-like nickel cyano-bridged coordination polymers (NiCNNi) are hybridized with GO sheets and thermally treated in air, so the organic materials can be removed without affecting the integrity of the parent GO sheets. Thus, the layer-by-layer construction followed by a thermal treatment can produce a new hybrid nanoporous material consisting of NiO and GO. The obtained hybrid material exhibits an efficient catalytic activity and stability for the oxygen reduction reaction (ORR).
在此，我们报道了一种涉及纳米多孔氧化镍薄片与氧化石墨烯（GO）片层杂交的新策略。所制备的片状镍氰基桥联配位聚合物（NiCNNi）与GO片层杂交并在空气中进行热处理，这样可以去除有机材料而不影响母体GO片层的完整性。因此，通过逐层构建并随后进行热处理，可以制备出一种由氧化镍和GO组成的新型杂化纳米多孔材料。所获得的杂化材料对氧还原反应（ORR）表现出高效的催化活性和稳定性。
