“…Using first principles calculations based on density functional theory, we study the impact of hole doping on the magnetic and electronic properties of two dimensional PtS(2). Although 2D PtS(2) is intrinsically non-magnetic, a stable ferromagnetic phase is found for a wide range of hole densities, owing to the so-called Stoner instabilities. …”

“…Although both the “nucleation and growth” and the “interface” mechanisms result in a core–shell configuration with a thin Pt-rich skin, Pt(85)Fe(15) NPs have an L1(2) Pt(3)Fe core, whereas Pt(65)Fe(35) NPs are composed of an L1(0) PtFe core. …”

“…In this study, graphene-supported nickel–iron layered double hydroxide (NiFe-LDH/rGO), in which Fe(3+) was introduced to replace Ni(2+) partially in the Ni(OH)(2) lattice to provide stronger metal–support bonding sites, was utilized to immobilize Pt nanoparticles (NPs). Given the optimized metal–support interfacial contact (Fe(3+)-O(H)-Pt) between Pt NPs and NiFe-LDH/rGO nanosheets for Pt/NiFe-LDH/rGO electrocatalysts, the Pt/NiFe-LDH/rGO electrocatalysts displayed dramatically enhanced durability than that of Pt/Ni(OH)(2)/rGO counterpart as well as commercial Pt/C, and 86.5% of its initial catalytic activity can be maintained even after 1200 cycles of cyclic voltammetry (CV) tests during MOR. …”
