Giving Electrocatalysts an Edge Platinum (Pt) is excellent catalyst for the oxygen-reduction reaction (ORR) in fuel cells and electrolyzers, but it too expensive scarce widespread deployment, even when dispersed as Pt nanoparticles on carbon electrode supports (Pt/C). Alternatively, Chen et al.

The construction of highly active and stable non-noble-metal electrocatalysts for hydrogen oxygen evolution reactions is a major challenge overall water splitting. Herein, we report novel hybrid nanostructure with CoP nanoparticles (NPs) embedded in N-doped carbon nanotube hollow polyhedron (NCNHP) through pyrolysis–oxidation–phosphidation strategy derived from core–shell ZIF-8@ZIF-67. Benefiting the synergistic effects between NPs NCNHP, CoP/NCNHP exhibited outstanding bifunctional...

Our catalyst exhibits high selectivity for CO2RR CO Faradaic efficiency (FECO) above 90% over wide potential range from -0.57 -0.88 V (the FECO exceeded 99% at -0.73 and -0.79 V). The current density remained nearly unchanged after electrolyzing 10 h, revealing remarkable stability....
Isolated single atomic site catalysts have attracted great interest due to their remarkable catalytic properties. Because of high surface energy, atoms are highly mobile and tend form aggregate during synthetic processes. Therefore, it is a significant challenge fabricate isolated with good stability.
