13C‐Labeled Mesoporous N‐Doped Carbon Nanospheres and N‐Doped Hydrothermal Carbon Aerogels as Model Materials for Carbon Corrosion Determination in Electrode Structures

open access: yesAdvanced Energy Materials, EarlyView.
By 13C labeling of carbon support materials used in energy storage and conversion applications, carbon corrosion can be investigated in situ via EC‐MS, giving information about the corrosion rate and whether the carbon support or other carbon‐containing materials in the system are degraded.

A Novel Ti12‐Based Metal‐Organic Framework for Photocatalytic Hydrogen Evolution

open access: yesAdvanced Energy Materials, EarlyView.
MIP‐209(Ti) is a new microporous MOF built up from Ti₁₂O₁₅ clusters and substituted terephthalate linkers, enabling isoreticular chemistry and clusters tunability for photocatalytic applications. Cr3⁺ doping (≤5 at%) on Ti‐oxoclusters drastically enhances water stability and boosts hydrogen production from water under simulated solar light irradiation.

Scandium Induced Structural Disorder and Vacancy Engineering in Li3Sb – Superior Ionic Conductivity in Li3−3xScxSb

open access: yesAdvanced Energy Materials, EarlyView.
A superionic conductivity of 42 mS cm−1 at 298 K is reported for Li2.55Sc0.15Sb, which exceeds the highest ionic conductivity reported for a solid Li‐ion conductor to date by 10 mS cm−1. In the series Li3−3xScxSb (0 < x ≤ 0.15), the gradual incorporation of Sc facilitates vacancy formation, converting pristine Li3Sb from an electrical to an ionic ...

Ru Single Atoms Anchored on Co3O4 Nanorods for Efficient Overall Water Splitting under pH‐Universal Conditions

open access: yesAdvanced Energy Materials, EarlyView.
A Ru8%‐Co3O4 catalyst containing Ru single atoms (SAs) exhibits exceptional oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) performance in acidic, neutral, and alkaline media. When used as the anode and cathode catalysts in an anion exchange membrane water electrolyzer (AEMWE) device, a low cell voltage of just 2.06 V is needed to

Phase Transition in Halide Double Perovskites for Solar‐To‐Chemical Energy Conversion

open access: yesAdvanced Energy Materials, EarlyView.
Disorder‐to‐order phase transition in double perovskite Cs2AgBiBr6 eliminates self‐trapped excitons and antisite defects and promotes charge separation, with over sixfold photoactivity enhancement in photocatalytic C−H bond activation. Abstract Halide double perovskites have recently garnered significant interest in solar energy conversion applications

Optimization of Adsorption Sites for Selective Hydrobenzoin and Syngas Production in a Single Photoredox Cycle

open access: yesAdvanced Energy Materials, EarlyView.
Efficient C─C coupling hydrobenzoin production and tunable syngas generation via benzyl alcohol oxidation and CO2 reduction is realized by Ni2P/CdS composite in a single photoredox cycle. In situ and ex situ characterizations, along with theoretical calculations, reveal that the active site optimization facilitates intermediate formation and desorption.

The Effect of Pore Functionality in Multicomponent Covalent Organic Frameworks on Stable Long‐Term Photocatalytic H2 Production

open access: yesAdvanced Energy Materials, EarlyView.
Five COFs are synthesized through a multicomponent reaction, preserving a similar backbone while introducing varying pore functionalities. All COFs demonstrate excellent chemical stability and sustained H2 production under sunlight for 7‐15 days. The imidazole‐functionalized COF exhibits the highest H2 production, which can be attributed to its high ...
