Popgraphene, a new 2D carbon allotrope constructed from 5–8–5 rings, is proposed for use in high-performance lithium-ion battery anodes.
The development of earth-abundant transition-metal-based electrocatalysts with bifunctional properties (oxygen evolution reaction (OER) and hydrogen (HER)) is crucial to commercial production. In this work, layered double hydroxide (LDH)-zinc oxide (ZnO) heterostructures oxygen vacancies are constructed synchronously by plasma magnetron sputtering NiFe-LDH. Using the optimal conditions, ZnO nanoparticles uniformly distributed on NiFe-LDH nanoflowers, which prepared three-dimensional porous...
Photothermal catalysis that utilizes solar energy to not only generate charge carriers but also supply heat input represents a potentially sustainable strategy for the efficient conversion of CO2 valuable chemicals. It is highly desirable develop photothermal catalysts with broadband light absorption across whole spectrum, conversion, and appropriate active sites.

Auxetic materials possess special applications due to their unique negative Poisson's ratios (NPRs). As a classic 2D carbon material, the NPR of graphene is still deliberated. Introducing in would increase its extraordinary properties, and together with other properties bring more significant for graphene. In this Letter, on basis first-principles calculations, we reconfigure structure graphene, and, as an example, propose new planar allotrope, xgraphene, which constructed by 5-6-7 rings....
Exploring new materials and methods to achieve high utilization of sulfur with lean electrolyte is still a common concern in lithium-sulfur batteries.

By using molecular dynamics simulations, the mechanical properties and failure mechanisms of a graphene sheet containing bi-grain-boundaries were examined. The results reveal that both temperature density defects play central roles in characteristics bi-grain-boundaries. increasing temperature, tensile strength fracture strain significantly decrease. high is much stronger than lower defects. dependence Young's modulus on also investigated. show processes sheets are dominated by brittle cracking.
By employing molecular dynamics simulations, a family of graphyne heterojunctions (GYHJs) made by two different graphynes (GYs) have been designed and prepared. The dependence tunable properties GYHJs, such as thermal conductivity, mechanical properties, interfacial resistance rectification, on the composition type GYHJs is determined. Upon changing GYHJ, one can keep constant value its fracture strength (and/or Young's modulus), while tuning conductivity. conductivities in zigzag direction...

Classic two-dimensional (2D) graphene possesses outstanding properties due to Dirac cone structures. When scaling up three-dimensional (3D) structures, their high porosity and large surface-area-to-volume ratio made them have more promising engineering perspectives. However, the currently synthesized density-functional-theory-predicted 3D termed as carbon honeycombs (CHCs), are metallic. Herein, we propose new families of stable semimetallic CHC which lower energies than previous...
