A general confinement co-assembly strategy enabling cross-dimensional supraspheres for boosting electrochemical performance

Modulating carrier transport by cross-dimensional compositing of Ag2Se/MXene for high-performance flexible thermoelectrics

“…Despite the boosting effect of MXene in MXene/carbon, 22 MXene/polymer, 23 and MXene/inorganic 24 TE nanocomposites, the possible synergistic effect with other dimensional materials especially one dimensional nano-fibers/wires as well as the optimal preparation strategy remain unresearched. This is very important in that cross-dimensional compositing has been shown to be promising to largely enhance the synergistic functionality, not only in the area of thermoelectrics, 25,26 but also magnetics, 27 electrochemistry, 28 photocatalysis, 29 etc. With the aim of preparing multidimensional composites that acquire high TE performance and good flexibility, we incorporate trace 2D MXene nanosheets (NSs) into 1D Ag 2 Se nanowires (NWs) matrix, where MXene acts as a bridge to connect nanowires that strengthens the linkage while regulating carrier transportation.…”

Efficient oxygen evolution reaction from iron-molybdenum nitride/molybdenum oxide heterostructured composites

“…However, the water electrolysis efficiency and large-scale industrial applications of state-ofthe-art electrocatalysts are persistently plagued by the sluggish kinetics and large overpotential of the oxygen evolution reaction (OER). 1,2 Thus, it is one of the urgent demands to develop and design efficient electrocatalysts with a favorable electron structure to ensure fast electron and mass transport and to boost OER kinetics. Transition metal nitrides (TMNs), especially N-rich Mo 5 N 6 -related systems with abundant N-metal bonds, are representative OER electrocatalysts because of their high electrical conductivity and similar electronic structure to noble metals, but their unsatisfactory durability and electrocatalytic activity limit their practical applications to some extent.…”
