Herein, a potassium phosphotungstate\/carbon nitride nanosheet (KPW\/CNS) heterojunction was constructed through a facile electrostatic assembly strategy for photocatalytic CO\n                    <jats:sub>2<\/jats:sub>\n                    reduction. The optimized photocatalyst (5KPW\/CNS) exhibited CH\n                    <jats:sub>4<\/jats:sub>\n                    and CO evolution rates of 6.3 and 9.3\u2009\u03bcmol\u2009g\n                    <jats:sup>\u22121<\/jats:sup>\n                    \u2009h\n                    <jats:sup>\u22121<\/jats:sup>\n                    , respectively, corresponding to a CH\n                    <jats:sub>4<\/jats:sub>\n                    selectivity of 40% and excellent photostability. In comparison, pristine CNS produced only 0.4\u2009\u03bcmol\u2009g\n                    <jats:sup>\u22121<\/jats:sup>\n                    \u2009h\n                    <jats:sup>\u22121<\/jats:sup>\n                    of CH\n                    <jats:sub>4<\/jats:sub>\n                    , and showed a much lower CH\n                    <jats:sub>4<\/jats:sub>\n                    selectivity of 7.0%. Combined X\u2010ray photoelectron spectroscopy, Kelvin probe force microscopy and density functional theory calculations revealed the formation of built\u2010in electric field at the KPW\/CNS interface, which drives an S\u2010scheme charge\u2013transfer pathway and promotes efficient spatial separation of photogenerated charge carriers. More importantly, mechanistic investigations demonstrated a cooperative catalytic pathway involving both components of the heterojunction. CNS primarily acts as the electron\u2010enriched site for CO\n                    <jats:sub>2<\/jats:sub>\n                    adsorption and activation to form *CO intermediates, whereas KPW facilitates the subsequent hydrogenation of *CO toward *CHO, *CH\n                    <jats:sub>2<\/jats:sub>\n                    O, and ultimately CH\n                    <jats:sub>4<\/jats:sub>\n                    .
