Defect‐Engineered Multi‐Intermetallic Heterostructures as Multisite Electrocatalysts for Efficient Water Splitting

open access: yesAdvanced Science, EarlyView.
A self‐supporting nanoporous multicomponent CoCuMoNi catalyst is synthesized. Through the synergistic effect of multiphase interfaces, built‐in electric fields, and defect engineering, the binding energy of key reaction intermediates in hydrogen evolution reaction (HER)/oxygen evolution reaction (OER) is modulated, achieving high activity and stability

Two‐Step Tandem Catalysis for High‐Efficiency Ammonia Synthesis Via Nitrate Reduction on Anion‐Intercalated CoNi LDH and Cu/Cu2O

open access: yesAdvanced Science, EarlyView.
By integrating Cu/Cu2O and CoNi LDH, tandem kinetic descriptors, including a volcano curve, are employed to predict rate constants, facilitating ideal kinetic matching for efficient ammonia synthesis. The highest ammonia yield (1.12 mmol cm−2 h−1) and Faraday efficiency (99.78%) are achieved by rate matching between Cu/Cu2O and MoO4‐CoNi LDH.

A Universal Approach to Anchoring Chromophores onto Magnetic Scaffold for Achieving Easily Recyclable Heterogeneous Photocatalytic Systems

open access: yesAdvanced Science, EarlyView.
The practical application of chromophores such as porphyrins, coumarins, anthraquinones, and pyrene derivatives in photocatalysis is severely limited by catalyst stability and reusability. In this work, a simple and universal strategy is presented for preparing highly efficient and recyclable heterogeneous photocatalysts for the oxidative coupling of ...

Robust Stick‐and‐Play Photothermal Icephobic Film with Bioinspired Insulation Cells

open access: yesAdvanced Science, EarlyView.
Inspired by the seed‐and‐framework structure of lotus seedpods, a photothermal anti‐icing film is developed by embedding thermal‐management hydrophobic microcells (THMC) into PDMS. Combining photothermal/insulating synergy and hydrophobic microcells, it achieves heat accumulation, surface adhesion, and robust anti‐icing under weak light, enabling ...
