Mn-, Co-, Ni-based oxides) have attracted considerable interest in searching for noble-metal-free materials as high-performance acidic OER electrocatalysts17,18,19,20,21,22. Nevertheless, the performance of these materials remains inferior to that of the noble metal-based catalysts, and most of...
Developing non-noble catalysts with superior activity and durability for oxygen evolution reaction (OER) in acidic media is paramount for hydrogen production from water. Still, challenges remain due to the inadequate activity and stability of the OER catalyst. Here, we report a cost-effective and ...

2.1Category and Basic Properties of 2D Materials Currently, the four most commonly utilized 2D materials in PSCs are graphene and its derivatives, TMDs, MXenes, and BP [45,57,61]. Besides, other 2D materials such as antimonene, hexagonal boron nitride (h-BN), metal-free carbon nitrides (...
accelerated and stable electrocatalysis. 16−18 Interface engineer- ing through various routes like chemical doping and post- treatment relates to weak (e.g., hydrogen bonding, electrostatic attraction, van der Waals interaction) or strong (e.g., covalent bonding) coupling effects. 19 Such a...
Non-precious-metal or metal-free catalysts with stability are desirable but challenging for proton exchange membrane fuel cells. Here we partially unzip a multiwall carbon nanotube to synthesize zigzag-edged graphene nanoribbons with a carbon nanotube backbone for electrocatalysis of oxygen reduction in ...
Red mud, one of the mostly produced industrial wastes, was converted into a catalyst with exceptionally high and stable performance for hydrogen production from ammonia. Results showed that iron species produced after reduction of the HCl digested red mu
