Under the global carbon neutrality initiative, the advancement of efficient and low-energy urea synthesis technologies holds crucial importance for sustainable development in agriculture and industry. Electrocatalytic technology enables direct co-reduction of CO2 and NO3– for urea synthesis under ambient conditions, emerging as a highly promising strategy that has garnered significant research interest. Nevertheless, current electrocatalytic systems are constrained by low mass transfer efficiency, insufficient catalytic activity, and poor stability, posing substantial challenges for developing high-performance electrocatalysts. In this study, a honeycomb-like porous AlCuZn alloy catalyst was successfully fabricated through a facile alkali etching approach. At ambient conditions, the optimized AlCuZn-0.5 catalyst demonstrated a remarkable urea Faradaic efficiency of 65.7% at –0.3 V (vs. RHE), representing 1.4-fold enhancement over pristine AlCuZn, with a corresponding yield of 152.4 μg/(h·mgcat) achieving 1.8-fold improvement. Electrochemical cycling tests and pre-/post-reaction X-ray diffraction (XRD) analyses confirmed catalyst's superior operational stability and structural integrity. The etched AlCuZn-0.5 manifests enhanced synergistic effects among Al-Cu-Zn components, which facilitated C-N coupling reactions and improved urea selectivity. Porous architecture of the material not only enhanced reactant mass transfer but also reduced charge transfer resistance while exposing abundant active sites, collectively boosting urea production rate. This work established a novel design paradigm of C-N coupling for efficient electrocatalysis of NO3– and CO2, positioning AlCuZn-0.5 as a prospective catalyst for sustainable urea synthesis.

在全球碳中和趋势下，开发高效低能耗的尿素合成技术具有重要意义。电催化技术可以在常温常压下直接将CO2和硝酸盐（NO3−）共还原合成尿素，是一种极具前景的策略，受到研究者广泛关注。然而，当前催化体系存在传质效率低、催化剂活性不足、稳定性差等问题，开发高效电催化剂依然面临巨大挑战。本研究通过简单的碱刻蚀方法，成功制备出蜂窝状多孔结构的AlCuZn合金催化剂。在设计环境条件下，AlCuZn-0.5催化剂在–0.3 V（vs. RHE）时尿素法拉第效率高达65.7%，是原始AlCuZn的1.4倍；产率为152.4 μg/（h·mgcat），是AlCuZn的1.8倍。循环试验和反应前后的X射线衍射（XRD）结果表明，改性后的AlCuZn具有良好的性能稳定性与结构稳定性。刻蚀后的AlCuZn-0.5和Al-Cu-Zn之间具有更好的协同效应，有利于C-N偶联反应的发生，提高了尿素的选择性；多孔结构提高了反应物的传质效率，降低了电荷转移阻力，同时也能暴露更多活性位点，有效提高尿素的生成速率。本研究制备的AlCuZn-0.5在尿素电催化合成中具有广泛应用前景，为高效电催化NO3−和CO2的C-N耦合提供了新的设计思路。

摘要

在全球碳中和趋势下，开发高效低能耗的尿素合成技术具有重要意义。电催化技术可以在常温常压下直接将CO2和硝酸盐（NO3−）共还原合成尿素，是一种极具前景的策略，受到研究者广泛关注。然而，当前催化体系存在传质效率低、催化剂活性不足、稳定性差等问题，开发高效电催化剂依然面临巨大挑战。本研究通过简单的碱刻蚀方法，成功制备出蜂窝状多孔结构的AlCuZn合金催化剂。在设计环境条件下，AlCuZn-0.5催化剂在–0.3 V（vs. RHE）时尿素法拉第效率高达65.7%，是原始AlCuZn的1.4倍；产率为152.4 μg/（h·mgcat），是AlCuZn的1.8倍。循环试验和反应前后的X射线衍射（XRD）结果表明，改性后的AlCuZn具有良好的性能稳定性与结构稳定性。刻蚀后的AlCuZn-0.5和Al-Cu-Zn之间具有更好的协同效应，有利于C-N偶联反应的发生，提高了尿素的选择性；多孔结构提高了反应物的传质效率，降低了电荷转移阻力，同时也能暴露更多活性位点，有效提高尿素的生成速率。本研究制备的AlCuZn-0.5在尿素电催化合成中具有广泛应用前景，为高效电催化NO3−和CO2的C-N耦合提供了新的设计思路。

Under the global carbon neutrality initiative, the advancement of efficient and low-energy urea synthesis technologies holds crucial importance for sustainable development in agriculture and industry. Electrocatalytic technology enables direct co-reduction of CO2 and NO3– for urea synthesis under ambient conditions, emerging as a highly promising strategy that has garnered significant research interest. Nevertheless, current electrocatalytic systems are constrained by low mass transfer efficiency, insufficient catalytic activity, and poor stability, posing substantial challenges for developing high-performance electrocatalysts. In this study, a honeycomb-like porous AlCuZn alloy catalyst was successfully fabricated through a facile alkali etching approach. At ambient conditions, the optimized AlCuZn-0.5 catalyst demonstrated a remarkable urea Faradaic efficiency of 65.7% at –0.3 V (vs. RHE), representing 1.4-fold enhancement over pristine AlCuZn, with a corresponding yield of 152.4 μg/(h·mgcat) achieving 1.8-fold improvement. Electrochemical cycling tests and pre-/post-reaction X-ray diffraction (XRD) analyses confirmed catalyst's superior operational stability and structural integrity. The etched AlCuZn-0.5 manifests enhanced synergistic effects among Al-Cu-Zn components, which facilitated C-N coupling reactions and improved urea selectivity. Porous architecture of the material not only enhanced reactant mass transfer but also reduced charge transfer resistance while exposing abundant active sites, collectively boosting urea production rate. This work established a novel design paradigm of C-N coupling for efficient electrocatalysis of NO3– and CO2, positioning AlCuZn-0.5 as a prospective catalyst for sustainable urea synthesis.
