Compared to the Run+ (where n = 2 or 3) homogenous catalysts that convert CO2 into methanol, 3d metal catalysts (such as Fen+, Con+, and Mnn+) exhibit poor activity due to catalyst poisoning and/or instability. Overcoming the hurdles observed in the case of 3d metal catalysts, in this article, we have unveiled a robust, cheap, and abundant Co(II) catalyst ([Li(DME)3][Co(L1)3]; 1, where L1 = 2,6-diisopropylanilide) which efficiently converts the CO2 into its methanol equivalent (B(OMe)3) in the presence of NaBH4, which upon hydrolysis yields methanol under mild conditions (0.1 bar CO2 and 60 °C) with the unprecedented TON and TOF of 11,171 and 508 h−1, respectively compared to any 3d metal catalyst reported to date. Further, we noticed that the activity of 1 was maintained for weeks, which is reflected in the overall TON of 54,000 obtained after 7 cycles. Moreover, we have shown that 1 can selectively reduce CO2 into methanol even from the “vehicle exhaust” directly. Systematic investigations were performed to shed light on the likely intermediates involved in the catalytic cycle, based on that we have proposed a mechanism for this reaction.
