This paper reports on metal phosphides as high-performance photothermal catalysts for solar-driven CO<sub>2</sub> hydrogenation. Ni<sub>12</sub>P<sub>5</sub>, an archetype, exhibits panchromatic absorption and a linearly bonded nickel-carbonyl-dominated reaction route, yielding a CO production rate of 960 ± 12 mmol g<sub>cat</sub><sup>−1</sup>h<sup>−1</sup> with near 100% selectivity and long-term stability. Extension to Co<sub>2</sub>P analogs suggests metal phosphides are a universal platform for high-rate, highly selective photothermal CO<sub>2</sub> catalysis.
