New 1D lanthanide-organic frameworks, [Ln(dpdc)1.5(IP)(H2O)]n (Ln = Sm 1, Eu 2, Gd 3; dpdc 2,2'-diphenyldicarboxylate and IP 1H-imidazo[4,5-f][1,10]-phenanthroline), were synthesized. White light emission was realized by two approaches: a single component Sm(iii) framework two-component Eu(iii)-doped Gd(iii) framework.
In thermoelectrics, phase engineering serves a crucial function in determining the power factor by affecting band degeneracy. However, for low-symmetry compounds, mainstream one-step manipulation strategy, depending solely on valley or orbital degeneracy, is inadequate to attain high density-of-states effective mass and exceptional zT. Here, we employ distinctive two-step strategy through stepwise tailoring chemical bonds GeSe. Initially, amplify degeneracy via CdTe alloying, which elevates...
Abstract In thermoelectric, phase interface engineering proves effective in reducing the lattice thermal conductivity via scattering and amplifying density-of-states mass by energy filtering. However, indiscriminate introduction of interfaces inevitably leads to diminished carrier mobility. Moreover, relying on a singular barrier is insufficient for comprehensive filtration low-energy carriers throughout entire temperature range. Addressing these challenges, we advocate establishment...
Cu-exchanged Y zeolite was investigated in order to determine the location of copper cations relative framework and which Cu are active for oxidative carbonylation methanol dimethyl carbonate (DMC). Cu−Y prepared by vapor-phase exchange H−Y with CuCl. The oxidation state, local coordination, bond distances Al were determined using K-edge X-ray absorption spectroscopy (XAS). Complimentary information obtained H2 temperature-programmed reduction in-situ infrared spectroscopy. has a Cu/Al ratio...
The metal particle size and structure of the metal−support interface platinum supported on Vulcan XC-72 (a commercial catalyst used in fuel-cell electrodes) carbon nanofibers (CNF) have been determined with extended X-ray absorption fine spectroscopy (EXAFS). CNF-supported Pt catalysts were synthesized using a homogeneous deposition precipitation (HDP) method. amount acidic oxygen groups CNF surface was modified by treatment an inert atmosphere at different temperatures. average first shell...
The complexes [Ln(3-SBA)(IP)OH(H2O)]·H2O (Ln = Gd 1 and Eu 2, 3-SBA 3-sulfobenzoate, IP 1H-imidazo[4,5-f][1,10]-phenanthroline) feature 1D chain structure. White-light emission was realized based on the doping concentration of Eu(III) ion in Gd(III) complex for first time. This result opens up a new synthetic strategy white light emitting materials through two component lanthanide–organic complexes.
Enhancing crystal symmetry is perceived as the most efficacious strategy to improve thermoelectric performance of GeSe. Although multicomponent alloying commonly employed increase symmetry, excessive point defects inevitably degrade carrier mobility. Herein, a new and promising proposed stabilize high‐symmetric rhombohedral GeSe by intentionally introducing cation vacancies. Specially, three compositional series GeSe(InSe) u , GeSe(InTe) v GeSe(InTe 3/2 ) x are studied highlight pivotal role...
Grain boundaries play a key role in carrier/phonon transport thermoelectric materials.
SnSe is considered as a thermoelectric material with great potential and advantages due to the record of high figure merit (ZT) 2.6 at 923 K in single crystals. However, it difficult use crystal practice its poor mechanical properties manufacturing costs. Meanwhile, polycrystalline also not suitable for applications much lower performance compared SnSe. Therefore, improving has become hot research topic. In this paper, AgSnSe2 doped into increase carrier density system thus improve...
