Abstract

A route to prepare nitrides, such as GaN, VN, and other nitrides, is reported. The reaction pathway involves a two-step process by using the as-synthesized a-C3N3.69 as precursor. The route is so potent that a series of nitrides can be directly synthesized from their oxides at moderate temperatures. A striking feature of this method lies in that a-C3N3.69 is found to play double roles as both carbonizing and nitridizing agent in these reactions. These results will greatly deepen our understandings of the mechanism for solid-state metathesis reactions.

摘要

报道了一种制备氮化物（如氮化镓、氮化钒和其他氮化物）的方法。该反应途径涉及一个两步过程，使用合成的a-C3N3.69作为前驱体。该方法非常有效，以至于一系列氮化物可以在中等温度下直接从其氧化物合成。该方法的一个显著特点在于，发现a-C3N3.69在这些反应中同时起到碳化剂和氮化剂的双重作用。这些结果将极大地加深我们对固态复分解反应机理的理解。
