Transforming carbon dioxide (CO2) into valuable chemicals is a key challenge in developing a sustainable carbon economy. While copper-based catalysts dominate the production of multicarbon (C2+) products, discovering entirely new catalyst families capable of promoting C鈥揅 coupling remains an open challenge.
In this work, we combined high-throughput density functional theory (DFT) calculations, thermodynamic and electrochemical stability analysis, and descriptor-based catalyst screening to explore a library of nearly 1,500 perovskite oxides. Through a systematic computational workflow, we narrowed the search to a small set of stable candidates and identified the ATaO3 perovskite family as a promising platform for CO2 electroreduction.
Our computational predictions led to the experimental validation of KTaO3, demonstrating that it can promote C鈥揅 coupling and the formation of C鈧� products, despite containing no copper. Electronic structure analysis revealed that the unique adsorption characteristics of the ATaO3 family closely resemble the balance of intermediate binding required for efficient C鈥揅 coupling, while mechanistic simulations uncovered a *CO鈥�*颁贬翱 coupling pathway responsible for multicarbon product formation.
This study establishes a computationally guided framework for accelerating catalyst discovery, illustrating how high-throughput screening, quantum mechanical simulations, and experimental validation can work together to identify entirely new classes of electrocatalysts for sustainable CO2 conversion.
