Inside Front Cover: Covalently Hydrophobic Nanocarbon Supported Ni Single‐Atom Catalysts for Highly Selective CO ₂ Electroreduction

In the Research Article e6865093, Jinlan Wang, Zhong Jin, Youfa Zhang, and co-workers covalently graft alkyl chains onto Ni single-atom catalysts supported by N-doped hollow carbon nanospheres to construct hydrophobic catalytic microenvironments. Such covalent hydrophobic functionalization disrupts interfacial water networks, raises the energy barrier for competing hydrogen evolution, stabilizes the key *COOH intermediate, and thus delivers near-unity CO selectivity alongside robust long-term electrolysis stability.
