Ion‐Confinement‐Assisted Erasure Purifies Oxidized MXene for Reuse

open access: yesAdvanced Science, EarlyView.
An erasure‐purification strategy removes surface‐derived TiO2 from oxidized Ti3C2Tx MXene by ion‐confinement‐induced interfacial conversion to soluble titanates, followed by brief acid washing. The scalable process enables approximately 70% material recovery, restores electrical conductivity, and recovers functional performance, including high ...

Amorphous BiSnxOy for Efficient CO2 Electroreduction to Formate via In Situ Doping

open access: yesAdvanced Science, EarlyView.
The amorphous BiSnxOy catalyst is electroreduced to Sn‐doped Bi during the electrochemical process. The Sn‐modulated Bi exhibits a favorable intermediate adsorption potential, leading to optimal catalytic efficiency. Remarkably, this catalyst demonstrates exceptional performance, achieving a Faradaic efficiency (FEformate) of 95.6% at 800 mA cm−2 in a ...

Photochemical Control of Perovskite Crystal Formation at Room Temperature

open access: yesAdvanced Science, EarlyView.
The authors demonstrate how ultraviolet (UV) light can enable the crystallization of two‐dimensional (2D) perovskite crystals that are otherwise difficult to grow using conventional thermal methods. These findings are supplemented with a detailed mechanistic description for the interaction of the UV irradiation with the perovskite precursor components.

Basal Plane Activation of SnS2 Thin‐Film by Fluorine Doping for Selective Solar‐Driven CO2 Reduction With Enhanced Quantum Efficiency

open access: yesAdvanced Science, EarlyView.
The synergistic effect of fluorine doping and sulfur vacancies boosts the activity of the active sites without active‐site modulation, leading to enhanced CO2 photoreduction efficiency and a selectivity switch from CH4 to CO on tin disulfide continuous thin films. ABSTRACT Photocatalytic conversion of CO2 into value‐added fuels offers a viable approach
