Multimetal doping is a promising strategy to achieve high-performance electrocatalysts for the oxygen evolution reaction (OER) due synergistic effects; however, understanding dynamic structure and clarifying catalytic mechanism of each individual metal in multimetal-based remain elusive. Here, we report synthesis homogeneous single-metal bimetal sulfides with pyrite OER catalysts via high-pressure high-temperature (HPHT) technique; operando Raman X-ray absorption spectroscopy (XAS) studies...
The electron-rich characteristic and low work function endow electrides with excellent performance in (opto)electronics catalytic applications; these two features are closely related to the structural topology, constituents, valence electron concentration of electrides. However, synthesized electrides, especially two-dimensional (2D) limited specific prototypes anionic
Nitride materials are of considerable interest due to their fundamental importance and practical applications. However, synthesis transition metal nitrides often requires extreme conditions, e.g., high temperature and/or pressure, slowing down the experimental discovery. Using global structure search methods in combination with first-principles calculations, we systematically explore stoichiometric phase space iron–nitrogen compounds on nitrogen-rich side at ambient pressures up 100 GPa....
Multicomponent alloying has displayed extraordinary potential for producing exceptional structural and functional materials. However, the synthesis of single-phase, multi-principal covalent compounds remains a challenge. Here, we present diffusion-controlled strategy realization transition metal carbides (MPTMCs) with single face-centered cubic phase. The increased interfacial diffusion promoted by addition nonstoichiometric compound leads to rapid formation phase at much lower sintering...
Accurate doping at special atomic sites can achieve effective control of active centers for the oxygen evolution reaction (OER), leading to synthesis intermediates with higher conversion efficiency.
Abstract The discovery of electrides, in particular, inorganic electrides where electrons substitute anions, has inspired striking interests the systems that exhibit unusual electronic and catalytic properties. So far, however, experimental studies such are largely restricted to ambient conditions, unable understand their interactions between electron localizations geometrical modifications under external stimuli, e.g., pressure. Here, pressure‐induced structural evolutions Ca 2 N by situ...
Diamane, the two-dimensional counterpart of diamond, is achieved from bi-layer graphene (BLG) or few-layer (FLG) through surface chemical adsorption high-pressure technology. Diamane with interlayer sp3 bonding found to have excellent heat transfer, ultra-low friction, high natural frequency, and tunable band gap, which shows potential technological industrial applications in nano-photonics, ultrasensitive resonator-based sensors, improved wear resistance. In this review, we summarize...
Abstract Developing and understanding electron-rich electrides offers a promising opportunity for variety of electronic catalytic applications. Using geometrical identification strategy, here we identify new class electride material, yttrium/scandium chlorides Y(Sc) x Cl y ( : < 2). Anionic electrons are found in the metal octahedral framework topology. The diverse dimensionality these is quantified explicitly by quasi-two-dimensional (2D) [YCl] + ∙e − [ScCl] one-dimensional (1D) [Y 2 3 ]...
