A novel reusable superhydrophilic NiO/Ni mesh produced by a facile fabrication method for superior oil/water separation

Journal Article


Abstract


  • There is a critical need to develop durable and reusable materials for

    oil–water separation, especially in harsh environments. Traditional antifouling

    mesh-based separation technologies are not reusable and

    limited by poor temperature resistance. Here we report a novel

    superhydrophilic and underwater superoleophobic NiO/Ni mesh which

    shows superior oil/water separation in harsh environments, with reusable

    and durable properties that can separate different oil–water

    mixtures with and without sand and soil contaminants, a >99% separation

    efficiency and up to 5.4 104 L m2 h1 permeate flux. The

    material is able to retain its superior performance over the 20 cycles we

    measured and for mixtures of sticky oils its performance is easily

    recoverable after a quick heat treatment. Our separation methodology

    is solely gravity-driven and consequently is expected to be highly

    energy-efficient. We anticipate that our separation methodology will

    have numerous applications, including in the clean-up of oil spills,

    wastewater treatment and other harsh condition oil–water separations.
