Highly Dispersed Indium Oxide Nanoparticles Supported on Carbon Nanorods Enabling Efficient Electrochemical CO₂ Reduction.

ABSTRACT: Indium-based materials can selectively reduce CO₂ to formate, but their activities still fall short of expectations to be considered for practical applications. Structural engineering at the nanoscale offers a promising solution. However, it is challenging to directly prepare nanostructures of metallic indium because of its low melting point and high oxophilicity. Herein, a strategy to prepare highly dispersed indium oxide nanoparticles as the precatalyst supported on conductive carbon nanorods from annealing the MIL-68 (In) precursor is proposed. When assessed in an H-cell, the product enables CO₂ reduction to formate with great faradaic efficiency of around 90% over a wide potential window in 0.5 m KHCO₃. When applied in a gas-diffusion-electrode-based fl
