Ce Single Atom‐Engineered Amorphous/Crystalline Nanosheets for Enhanced Alkaline Water Electrolysis

open access: yesAdvanced Materials, EarlyView.
We leveraged Ce single‐atom engineering to generate short‐range ordered crystalline nanodomains in amorphous RuOx for creating amorphous/crystalline nanojunctions, in an effort to regulate the water dissociation kinetics for enhanced HER. Specifically, the Ce‐doped crystalline nanodomains greatly reduce the energy barrier to water dissociation and ...

De‐Saturation of Single‐Atom Copper Catalysts for Accelerating Propargylic Substitution Reactions

open access: yesAdvanced Materials, EarlyView.
De‐saturation of copper‐based single‐atom catalysts (De‐sat SACs) are realized by a KOH‐mediated Joule thermal shock strategy. Benefiting from the under‐saturation coordination environment of single‐atom Cu center, De‐sat Cu SACs exhibit remarkable catalytic activity in propargylic substitution reactions, tolerating a broad range of nucleophiles (N–, C–

Rigid Supramolecular Aramid Nanotubes as Catalyst Supports

open access: yesAdvanced Materials, EarlyView.
Molecular nanotube self‐assemblies with high aspect‐ratios and stiffness are demonstrated as nanocatalyst supports. The extended dimensions and tunable surface chemistries of the nanotubes enable tethered gold nanoparticle catalysts to remain dispersed in solution and to be easily recovered through simple filtration.

Role of Liquid Composition in the Transient Liquid Assisted Growth of Superconducting YBa2Cu3O7‐δ Films

open access: yesAdvanced Materials, EarlyView.
The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.
