摘要
以清洁能源为动力的电化学二氧化碳还原(ECR)反应在减少二氧化碳排放和实现碳循环方面前景广阔。本文以共价有机框架(COF)为模板,制备了具有封装结构的 Ni@N-C 电催化剂,其中利用 COF 衍生的掺氮碳(N-C)来包裹 Ni 纳米粒子。在相对于 RHE 的 -0.97 V 电位下,2Ni@N-C-800 具有高电流密度(j = 24.2 mA cm-2)和相对较高的一氧化碳法拉第效率(FECO = 72%),反映了其良好的催化活性。2Ni@N-C-800 的 ECR 性能得益于镍纳米颗粒与 N-C 结构之间的协同作用,这是从控制和中毒测量中推断出来的。这项研究为寻找高效稳定的 ECR 催化剂提供了新思路。
Nitrogen-Doped Carbon-Encapsulated Nickel Nanoparticle Catalysts Using Covalent Organic Frameworks as Templates for Electrochemical CO2 Conversion
Electrochemical CO2 reduction (ECR) reactions, powered by cleaner energy, possess significant promise in mitigating CO2 emissions and achieving carbon recycling. Herein, Ni@N-C electrocatalysts with encapsulated structures are prepared using covalent organic frameworks (COFs) as templates, where COF-derived nitrogen-doped carbon (N-C) is utilized to wrap Ni nanoparticles. At the potential of −0.97 V vs. RHE, 2Ni@N-C-800 is characterized by a high current density (j = 24.2 mA cm-2) and relatively high CO Faraday efficiency (FECO = 72%), reflecting its good catalytic activity. The ECR performance of 2Ni@N-C-800 is due to the cooperative interaction between Ni nanoparticles and the N-C structure, which is inferred from control and poisoning measurements. This study provides a new idea for finding efficient and stable ECR catalysts.
