Two-dimensional (2D) transition-metal nitrides just recently entered the research arena, but already offer a potential for high-rate energy storage, which is needed portable/wearable electronics and many other applications. However, lack of efficient high-yield synthesis methods 2D metal has been major bottleneck manufacturing those potentially very important materials, only MoN, Ti4N3, GaN have reported so far. Here we report scalable method that uses reduction hexagonal oxides in ammonia...
Heteroatom-doping is a practical means to boost RuO2 for acidic oxygen evolution reaction (OER). However, major drawback conventional dopants have static electron redistribution.
