The significance of the exogenous delivery versus the in-situ synthesis from atmospheric gases is still under debate. We experimentally demonstrate that iron-rich meteoritic and volcanic particles activate and catalyse the fixation of CO2, yielding the key precursors of life-building blocks. This catalysis is robust and produces selectively aldehydes, alcohols, and hydrocarbons, independent of the redox state of the environment. It is facilitated by common minerals and tolerates a broad range of the early planetary conditions (150\u2013300 \u00b0C, \u2272 10\u201350 bar, wet or dry climate). We find that up to 6 \u00d7 108 kg\/year of prebiotic organics could have been synthesized by this planetary-scale process from the atmospheric CO2 on Hadean Earth.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sophia Peters, Dmitry A.
