Abstract

The electrocatalytic nitrogen reduction reaction (ENRR) offers a sustainable and cost-effective strategy for ammonia (NH₃) synthesis. However, the broad applicability of ENRR is currently limited by challenges in the adsorption and activation of N₂ at the catalyst interface. Addressing these issues, we have developed an innovative approach that constructs an interfacial electric field, coupled with an atomically local electric field induced by W-N bonds. This coupled interfacial-local electric field effectively elevates the d_z² occupancy of W active sites, thereby significantly enhancing the adsorption and activation of N₂. This work provides profound insights into the relationship between the interfacial-local electric field and the efficient execution of ENRR, paving the way for future explorations and potential breakthroughs within catalytic field.

通过界面-局部耦合电场调节 d-轨道占用率，实现电催化 N2 固定

电催化氮还原反应（ENRR）为合成氨（NH3）提供了一种可持续且具有成本效益的策略。然而，ENRR 的广泛适用性目前受到催化剂界面吸附和活化 N2 的挑战的限制。为了解决这些问题，我们开发了一种创新方法，即构建一个界面电场，再加上由 W-N 键诱导的原子局部电场。这种界面-局部耦合电场可有效提高 W 活性位点的 dz2 占有率，从而显著增强 N2 的吸附和活化。这项研究深入揭示了界面-局部电场与 ENRR 高效执行之间的关系，为催化领域的未来探索和潜在突破铺平了道路。
