Synthesis of Cu₃N from CuO and NaNH₂

Peer review under responsibility of The Ceramic Society of Japan and the Korean Ceramic Society.

Abstract

We report on the low-temperature synthesis of submicron-sized Cu₃N powder produced from CuO and NaNH₂ powder mixture by heating at 150–190 °C in a Teflon-sealed autoclave. The structure was the anti-RuO₃ type with a lattice parameter of 0.3814(1) nm, and strong optical absorption was observed below ∼1.9 eV. This synthesis method has the potential of facile control of the reaction with less use of ammonia sources.
