Developing Type-I core/shell quantum dots is of great importance toward fabricating stable and sustainable photocatalysts. However, the application systems has been limited due to strongly confined photogenerated charges by energy barrier originating from wide-bandgap shell material. In this project, we found that through decoration Au satellite-type domains on surface CdS/ZnS dots, such an can be effectively overcome over 400-fold enhancement photocatalytic H2 evolution rate was achieved...
Abstract Crystalline carbon nitride (CCN), derived from amorphous polymeric CN, is considered as a new generation of metal‐free photocatalyst because its high crystallinity. In order to further promote the photocatalytic performance CCN, p‐type MnO nanoparticles are in situ synthesized and merged with n‐type CCN through one‐pot process form p–n heterojunction. The formed interfacial electric field between semiconductors different work functions efficiently breaks coulomb interaction CCN....
Monolayer transition metal dichalcogenides (TMDs) have been regarded as the most promising low-cost alternatives to noble metals catalysts for hydrogen evolution reaction (HER). However, their limited catalytically active sites HER hinder practical application. In this paper, catalytic performances of edge Janus monolayer MoXY (X/Y = S, Se and Te) were investigated using density functional theory. The results show that both Mo-edge chalcogen atomic edges are HER; thus exhibits better...
Two-dimensional materials have attracted much attention due to their good thermoelectric (TE) performance caused by the unique density of states at Fermi energy and low lattice thermal conductivity. Inspired high TE bulk Sb2Si2Te6, in this work, electronic transport, properties Sb2X2Te6 (X = Si, Ge) monolayers were investigated using functional theory combination with semiclassical Boltzmann transport theory. The results indicate that are dynamically indirect semiconductors. Sb2Si2Te6...
The diffusion behavior of lithium in the α-Sn and β-Sn were investigated using density function theory (DFT). barrier single atom is 0.21 eV, which shows a little change as another was next to it. However, 0.39eV for tend bond together when more atoms appear. different barriers are attributed binding energy Li-Li Sn with crystal structures. used an anode material ion batteries preferable fast lithium.
A low thermal conductivity and a high power factor are essential for efficient thermoelectric materials. The lattice can be reduced by reducing the dimensions of materials, thus improving performance. In this work, electronic, carrier phonon transport properties ZrNX (X = Cl, Br, I) monolayers were investigated using density functional theory Boltzmann theory. electronic show anisotropic properties. conductivities 20.8, 14.6 12.4 W m-1 K-1 at room temperature along y-direction ZrNCl, ZrNBr,...
This device demonstrated a magnetization-controlled diode-like behavior with forward-allowed current under antiparallel magnetizations and reverse-forbidden parallel of the two electrodes.
Using first principles calculation based on density functional theory, effect of Al-doping the adsorption and diffusion behavior Li/Na/Mg in Ge was investigated. Results show that undoped is unfavorable for Na Mg insertion.

Single-atom catalysts (SACs) have attracted wide attention to be acted as potential electrocatalysts for nitrogen reduction reaction (NRR). However, the coordination environment of single transition metal (TM) atoms is essential catalytic activity NRR. Herein, we proposed four types 3-, 4-coordinated and π-d conjugated TM
Thermoelectric (TE) materials have attracted great attention in solving the problems waste heat field, while low figure of merit and poor material stability drastically limit their practical applications. In this work, a two-dimensional (2D) Sc2Si2Te6 monolayer was systematically explored as promising TE via ab initio methods. The results reveal that possesses an indirect band gap with rhombohedral crystal phase exhibits excellent dynamic stability. lower electronic/lattice thermal...
