Polymer-derived nanostructured anti-perovskite non noble metal nitrides.
Herein, we report the one-step design of a novel composition of nanocomposites made of an amorphous silicon nitride ('SiN') matrix with embedded anti-perovskite nitride Ni3CuN nanoparticles (NPs). Such compounds are prepared from a metal-modified polysilazane (PSZ) synthesized by the controlled reaction of the PSZ itse...
