Oxygen‐Vacancy‐Rich Heterostructured CeO 2 ‐CuO Nanowires for Urea Electrosynthesis via Co‐Reduction of Nitrate and CO 2
Source abstract
Abstract
Abstract The mild electrosynthesis of urea presents a promising approach to replace the energy‐intensive conventional manufacturing processes, and identifying highly active and selective electrocatalysts is of paramount importance. Herein, the synthesis of oxygen‐vacancy‐rich CeO 2 ‐CuO heterostructure nanowires on copper foam (CeO 2 ‐CuO/CF) are reported. The CuO‐CeO 2 heterostructure notably enhances electron transfer and quickens reaction dynamics, and the increased oxygen vacancies greatly promote the C‐N coupling of nitrate and CO 2 to urea. As such, the CeO 2 ‐CuO/CF achieves a remarkable faraday efficiency of 31.96% and urea yield of 720.9 µg cm −2 h −1 , along with outstanding stability. This research offers a promising electrocatalyst for the sustainable on‐site production of urea.
