N₂-to-NH₃ conversion by excess electrons trapped in point vacancies on 5f-element dioxide surfaces.

ABSTRACT: Ammonia (NH₃) is one of the basic chemicals in artificial fertilizers and a promising carbon-free energy storage carrier. Its industrial synthesis is typically realized via the Haber-Bosch process using traditional iron-based catalysts. Developing advanced catalysts that can reduce the N₂ activation barrier and make NH₃ synthesis more efficient is a long-term goal in the field. Most heterogeneous catalysts for N₂-to-NH₃ conversion are multicomponent systems with singly dispersed metal clusters on supporting materials to activate N₂ and H₂ molecules. Herein, we report single-component heterogeneous catalysts based on 5f actinide dioxide surfaces (ThO₂ and UO₂) with oxygen vacanci
