The homojunction of oxygen/metal vacancies and its interfacial n-p effect on the physiochemical properties are rarely reported. Interfacial homojunctions TiO2 fabricated by directly decorating p-type titanium-defected around n-type oxygen-defected nanocrystals in amorphous-anatase homogeneous nanostructures. Experimental measurements theoretical calculations cell lattice parameters show that oxygen titanium changes charge density ; a strong EPR signal caused an unreported 2D 1 H TQ-SQ MAS...
MXenes are 2D transition metal carbides, nitrides, and/or carbonitrides that can be intercalated with cations through chemical or electrochemical pathways. While the insertion of alkali and alkaline earth into Ti3C2Tx is well studied, understanding intercalation redox-active ions its impact on their electronic properties lacking. In this work, we investigate Cu MXene effect properties. Using X-ray absorption spectroscopy (XAS) ab initio molecular dynamics (AIMD), observe an unusual...
Transition metal (TM) cations exhibit distinct electronic properties, compared to alkali and alkaline earth cations. In this work, we aim explore the coupling between different redox-active TMs guest conductive MXene host. Specifically, within confined environment of layers, inserted TM demonstrate varying structures exert influences on MXene. Unlike Cu which undergoes unusual reduction upon insertion MXenes, our Bader charge analysis X-ray absorption spectroscopy (XAS) results indicate that...
BaSnF4 is a prospective solid state electrolyte for fluoride ion batteries. However, the diffusion mechanism of ions remains difficult to study, both in experiments and simulations. In principle, ab initio molecular dynamics could allow fill this gap, but method very costly from computational point view. Using machine learning potentials promising that can potentially address accuracy issues classical empirical while maintaining high efficiency. work, we fitted dipole polarizable model...
Solid state ionic conductors are of primary importance for the design tomorrow's batteries. In lithium ion or sodium ion-based materials, alkali cations diffuse through three-dimensional channels consisting interconnected tetrahedral octahedral sites with low free energy barriers between them. Fluoride stand out in this landscape since materials highest conductivities belong to MSnF4 family (in which M2+ is a divalent cation), structure layered and characterized by double-layers Sn2+ along...
