The crystal facets featured with facet-dependent physical and chemical properties can exhibit varied electrocatalytic activity toward hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) attributed to their anisotropy. The highly active exposed crystal facets enable increased mass activity of active sites, lower reaction energy barriers, and enhanced catalytic reaction rates for HER and OER. The formation mechanism and control strategy of the crystal facet, significant contributions as well as challenges and perspectives of facet-engineered catalysts for HER and OER are provided.
具有依赖于晶面的物理和化学性质的晶面，由于其各向异性，对析氢反应（HER）和析氧反应（OER）可表现出不同的电催化活性。高活性的暴露晶面可提高活性位点的质量活性、降低反应能垒，并提高HER和OER的催化反应速率。本文介绍了晶面的形成机理和控制策略，以及晶面工程催化剂对HER和OER的重大贡献、挑战和展望。
