Monodispersed PtCo alloy nanoparticles with a modulated d-band center exhibiting highly efficient hydrogen evolution

“…[34][35][36] Besides, upon annealing at high temperatures, numerous active sites, rich pores, and favorable conductivity were expected, which deliver highly active performance. 37,38 To address the above-mentioned electronic modulation of alloys and eminent property of porous ZIFs, in this work, two types of ZIF derived nitrogen-containing porous carbon were employed as substrates to fabricate PtCo alloy nanoparticles deposited nitrogen doped carbon electrocatalyst (PtCo-NC). By utilizing the unique porous carbon substrate, a PtCo alloy nanoparticle (2.03 nm) with high density of active sites and optimum morphology, appropriate size, and good dispersion anchored on the intact dodecahedral structure was intentionally constructed.…”
