Showcasing a study on nitrogen and nickel co-doped carbon nanotubes and their application in CO 2 reduction by a group of researchers led by Prof. Jing-Li Luo and Prof. Xian-Zhu Fu from Shenzhen University. Novel folic acid complex derived nitrogen and nickel co-doped carbon nanotubes with embedded Ni nanoparticles as efcient electrocatalysts for CO 2 reduction Uniform and highly porous Ni & N co-doped CNTs with embedded Ni nanoparticles were prepared from a sustainable bioligand-folic acid via a template-free method and exhibited superior electrocatalytic activity for CO 2 reduction to CO.
