1D/3D hierarchical carbon skeleton confined NiFe nanoparticles with optimized three-phase interfaces as tri-functional electrocatalyst

Researchers have developed a novel carbon nanotube-modified 3D hollow carbon sphere (N-HCS@NiFe) that serves as an efficient electrocatalyst for energy conversion applications. The material demonstrates excellent performance in oxygen evolution reaction (OER), urea oxidization reaction (UOR), and oxygen reduction reaction (ORR) with strong stability at high current density.
