Congratulations to Jiuli and coauthors on their publication in Advanced Science!

CO2 reduction to commodity chemicals and fuels holds great promise to alleviate the global warming. The realization typically requires earth-abundant catalysts and inexpensive driving force. In this paper, Jiuli and coauthors reported a Cu2+-substituted hydroxyapatite (Ca10(PO4)6(OH)2) mineral photocatalyst achieving peak CO2-to-CO performance of 215 μmol per gram catalyst per hour without CH4 byproduct. The activity originates from novel active sites of surface frustrated Lewis pairs—the proximal Lewis acidic Cu2+ and Lewis basic OH-, which selectively produce CO via a formate intermediate.
