Bifunctional Electrocatalysts in Rechargeable Lithium‐Gas Batteries: Material Evolution and Mechanistic Insights from Metal‐Free Carbons to Carbon‐Supported Single‐Atom Sites

open access: yesSmall, EarlyView.
This review charts the material evolution of bifunctional electrocatalysts for rechargeable lithium‐gas batteries. It highlights the journey from heteroatom‐doped, metal‐free carbon architectures to precision‐engineered carbon‐supported single‐atom sites. The discussion focuses on mechanistic insights into how these catalysts govern reversible O2, CO2,

A Versatile Heterometallic Microporous MOF for Photocatalytic Hydrogen Generation

open access: yesSmall, EarlyView.
This work describes a green and scalable approach to robust and flexible heterometallic MOFs, MIP‐215's, with tunable photoactivity for efficient, noble‐metal‐free solar hydrogen production. ABSTRACT Photocatalytic particulate systems offer a cost‐effective solar hydrogen production but are generally limited by narrow visiblelight absorption and poor ...

Interface Modulation of rGO/Bi0/BiOCl Enables Efficient Electron Utilization for CO2 Photoreduction

open access: yesSmall, EarlyView.
A one‐step strategy constructs a coupled rGO/Bi0/BiOCl interface that shifts electron behavior from trapping to dynamic utilization, enabling improved CO2 photoreduction toward hydrocarbon products with enhanced selectivity (92%) toward CH4 and C2H4 and exhibits a 12‐fold increase in CH4 photoreduction activity compared to pristine water made BiOCl ...

Fragmentation‐Locked Polymeric Carbon Nitride Enables Global‐to‐Local Electron Allocation for Enhanced Peroxymonosulfate Activation

open access: yesSmall, EarlyView.
A NaI‐assisted polymeric carbon nitride photocatalyst enables visible‐light‐driven peroxymonosulfate activation through fragmentation‐locked structural and electronic regulation. Iodide‐induced ultrathin nanosheets expose abundant active sites, while sodium ions promote global‐to‐local electron allocation toward peroxymonosulfate.
