Developing substitutes of noble metal catalysts toward oxygen reduction reaction (ORR) at the cathode is vital importance for promoting low‐temperature polymer electrolyte membrane fuel cells. Transition species have been one hot areas interest due to their low cost, high activity, and long‐term stability. The design porous carbon nanostructures decorated with transition plays a role in enhancing ORR catalytic performance. Here, recent breakthroughs (including nanoparticles atomically...
Abstract Freestanding composite structures with embedded transition metal dichalcogenides (TMDCs) as the active material are highly attractive in development of advanced electrodes for energy storage devices. Most 3D consist a bilayer design involving core–shell combination. To further enhance gravimetric and areal capacities, trilayer is proposed that has MoSe 2 TMDC sandwiched in‐between an inner carbon nanotube (CNT) core outer layer to form CNT/MoSe /C framework. The CNT creates...
