Nitrous oxide (N2O) is a potent greenhouse and ozone‐reactive gas for which emissions are growing rapidly due to increasingly intensive agriculture. Synthetic catalysts for N2O decomposition typically contain precious metals and/or operate at elevated temperatures driving a desire for more sustainable alternatives. Here we demonstrate self‐assembly of liposomal microreactors enabling catalytic reduction of N2O to the climate neutral product N2. Photoexcitation of graphitic N‐doped carbon dots delivers electrons to encapsulated N2O Reductase enzymes via a lipid‐soluble biomolecular wire provided by the MtrCAB protein complex. Within the microreactor, electron transfer from MtrCAB to N2O Reductase is facilitated by the general redox mediator methyl viologen. The liposomal microreactors use only earth‐abundant elements to catalyze N2O removal in ambient, aqueous conditions. Self‐assembled liposome microreactors mimic the spatial separation of redox reactions seen in respiration and photosynthesis. Catalytic reduction of the climate heating gas N2O to benign N2 by encapsulated enzyme is driven by irradiation of external carbon dots through an electron transfer pathway defined by a membrane‐spanning cytochrome and redox‐cycling of internal methyl viologen.
