Multiple Active Sites Engineering in Cu/γ‐Al2O3 Catalyst Enables Selective Electrocatalytic CO2 Reduction to Methane at High Rates

open access: yesCarbon Energy, EarlyView.
A multi‐site heterogeneous electrocatalyst is designed, composed of Cu nanoclusters supported on γ‐Al2O3. Within this system, CO2 activation, H2O dissociation, and *CO protonation are respectively governed by the Cu sites, γ‐Al2O3 sites, and the Cu/γ‐Al2O3 interface sites.

Directed Charge Transfer‐Driven Efficient Photocatalytic Hydrogen Production in Dual S‐Scheme WS2/Co9S8/ZnCdS Heterojunction

open access: yesCarbon Energy, EarlyView.
The photocatalytic hydrogen evolution reaction (HER) activity of the polyoxometalate (POM)‐derived dual S‐scheme heterojunction photocatalyst WS2/Co9S8/ZnCdS reaches a value as high as 15.66 mmol g−1 h−1 under visible light (λ ≥ 420 nm), providing a straightforward approach for the development of dual S‐scheme heterojunctions to enhance the efficiency ...

Enabling Wide‐Temperature Range Li‐S Batteries via Asymmetric‐Coordinated Titanium Sites‐Implanted Graphene Single‐Atom Electrocatalysts

open access: yesCarbon Energy, EarlyView.
A Ti‐based single‐atom catalyst featuring isolated Ti atoms anchored on reduced graphene oxide (Ti‐rGO) has been successfully synthesized as a sulfur host material. This Ti‐rGO composite effectively integrates the robust adsorption capacity of Ti‐O5 coordination groups toward LiPSs with the rapid mass transport kinetics inherent to its porous ...

Functionalized Organic Lithium Salt Enables Flexible Solid‐State Electrolytes With Dual‐Ion Channels for Safe Li Metal Batteries

open access: yesCarbon Energy, EarlyView.
Here, we design a flexible and non‐flammable solid‐state electrolyte with hierarchical dual‐ion conductive channels. The engineered electrolyte combines continuous organic conductive‐phase pathways for fast bulk Li+ transport and dynamic polymer networks for interfacial ion hopping, achieving unprecedented room temperature conductivity (> 1 mS cm−1 ...

Characterization of the permeability evolution of hard and soft rocks under hydro‐mechanical coupling conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
The permeability variation of rocks during complete stress–strain processes was investigated. A mathematical model describing the influence of rock damage on permeability was constructed. The permeability–stress relationship between soft rock and hard rock was proposed.

Creep properties and constitutive model of diabase in deep water conveyance tunnels

open access: yesDeep Underground Science and Engineering, EarlyView.
The axial and lateral creep characteristics of diabase were analyzed based on compression creep tests. The nonlinear viscoelastic‐plastic model capable of describing the whole creep process was established based on the fractional derivative and damage theories.
