Research summary
An atomically dispersed Pd_1/TiO_2 catalyst was prepared by a photochemical route on ethylene-glycolate-stabilised ultrathin TiO_2 nanosheets at Pd loading up to 1.5%, with C=C hydrogenation activity nine times that of commercial Pd surface atoms and no decay after 20 cycles [1]. An Fe-N-C oxygen-reduction electrocatalyst combining Fe-N_x coordination and Fe/Fe_3C nanocrystals was characterised across a designed catalyst series to establish that Fe/Fe_3C nanoparticles amplify Fe-N_x intrinsic activity [2]. Small sulfur allotropes S_{2-4} were synthesised in a conductive microporous-carbon host to suppress soluble-polysulfide intermediates in Li-S cathodes [3]. Ultrafine jagged Pt nanowires were formed from solution-synthesised Pt/NiO core/shell nanowires by thermal annealing to PtNi alloys followed by electrochemical dealloying, achieving an ECSA of 118 m^2/g_Pt, a specific activity of 11.5 mA/cm^2 at 0.9 V vs RHE, and a mass activity of 13.6 A/mg_Pt for oxygen reduction [4]. A joint experimental and theoretical study of point defects in monolayer MoS_2 prepared by mechanical exfoliation, physical CVD, and chemical CVD identified defect species and quantified concentrations up to 3.5 x 10^13 cm^-2 by aberration-corrected scanning transmission electron microscopy and ab-initio calculations [5]. Rhombohedral and tetragonal polymorphic nanodomains were embedded in a cubic matrix of lead-free relaxor-ferroelectric solid-solution films, producing an energy density of 112 J/cm^3 at ~80% efficiency with minimised hysteresis [6].
