Fe 3 C Nanorods Encapsulated in N-Doped Carbon Nanotubes as Active Electrocatalysts for Hydrogen Evolution Reaction
One of the main challenges to generate hydrogen is to develop cheap and highly active electrocatalysts toward hydrogen evolution reaction (HER). Herein, Fe3C nanorods encapsulated in N-doped carbon nanotubes (Fe3C@NCNT) were synthesized by a simple method involving the pyrolysis of a Fe-based metal organic framework (MOF) and melamine. The hybrid composite showed an excellent catalytic activity toward HER in an acidic electrolyte. The overpotential at the current density of 10 mA cm−2 was only 154 mV in a 0.5 M H2SO4 solution, which was lower than most of the non-precious metal and metal-free catalysts. Density functional theory (DFT) calculation results suggested that the synergistic effect between Fe3C nanorods and N dopants could effectively tune the H adsorption energy on carbon resulting in an enhanced HER activity.

Keeping up-to-date with research can feel impossible, with papers being published faster than you'll ever be able to read them. That's where Researcher comes in: we're simplifying discovery and making important discussions happen. With over 19,000 sources, including peer-reviewed journals, preprints, blogs, universities, podcasts and Live events across 10 research areas, you'll never miss what's important to you. It's like social media, but better. Oh, and we should mention - it's free.
Researcher displays publicly available abstracts and doesn’t host any full article content. If the content is open access, we will direct clicks from the abstracts to the publisher website and display the PDF copy on our platform.
