AbstractSection Highlights

• The Bi₂O₃ nanoplates homogeneously decorated free-standing exfoliated graphene (Bi₂O₃/FEG) was prepared by a facile electrochemical deposition method.

• The Bi₂O₃/FEG first used as nitrogen reduction electrocatalyst exhibits excellent electrocatalysis performance and stability for nitrogen reduction reaction in neutral media.

• The superior electrocatalytic nitrogen reduction activity is attributed to the strong interaction of the Bi 6p band with the N 2p orbitals, binder-free nature of the electrodes, and facile electron transfer through the graphene nanosheets.

中性介质中环境条件氨生产的基于铋的自由电极

摘要部分重点

• 通过一种简便的电化学沉积方法制备了Bi ₂ O ₃纳米板，均匀装饰的自立式脱落石墨烯（Bi ₂ O ₃ / FEG）。

• 首次用作氮还原电催化剂的Bi ₂ O ₃ / FEG在中性介质中表现出优异的电催化性能和氮还原反应的稳定性。

• 优异的电催化氮还原活性归因于Bi 6 p带与N 2 p轨道之间的强相互作用，电极的无粘结剂性质以及通过石墨烯纳米片的便捷电子转移。
