Vapor‐Assisted Catalysis Enables Precise Construction of MOF‐Derived Hierarchical Carbon Nanoarrays for High‐Performance Supercapacitors

open access: yesAdvanced Science, EarlyView.
A remote‐control strategy for catalyst design is unveiled for advanced carbon materials. During pyrolysis, zinc vapor from a physically separate source guides cobalt catalysts to construct a hierarchical carbon nanoarray. This approach prevents structural collapse while directing the dense growth of carbon nanotubes, yielding a material with ...

Compositional Tuning and Surface Restructuring Synergistically Enhance Perovskite Ferrite Catalysts for Hydrogen Evolution in a Membrane‐Less Electrolyzer

open access: yesAdvanced Energy Materials, EarlyView.
In this work, a self‐restructuring Fe‐based perovskite catalyst is developed, leveraging in situ amorphization to achieve a “self‐improving” behavior for hydrogen evolution. When integrated into a custom‐built membrane‐less electrolyzer, the system demonstrates a record‐breaking 1000 h stability, providing a robust and practical pathway for the ...

Beyond Imperfect Match: Silicon/Graphite Hybrid Anodes for High‐Energy–Density Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Silicon/graphite (Si/Gr) hybrid anodes are limited by Si's large volume change and mismatch with Gr. This review offers mechanistic insights into imperfectly matched Si/Gr hybrid anodes, elucidating heterogeneous lithiation behavior and interfacial failure pathways, and thereby informing the design of durable, high‐energy–density lithium‐ion batteries.

CO Spillover‐Induced Directed C─C Coupling for CO2 Electroreduction to Multicarbon Products

open access: yesAdvanced Energy Materials, EarlyView.
Efficient CO2 electroreduction to C2+ is achieved by engineering Cu@Ag interfaces, which enhance interfacial CO spillover from Ag to Cu, enrich *CO coverage, and accelerate C─C coupling. A quantitative relationship between CO spillover rate and C2+ activity is also established, defining spillover as a measurable descriptor and advancing rational ...
