Toward Complete CO2 Electroconversion: Status, Challenges, and Perspectives

open access: yesAdvanced Energy Materials, EarlyView.
Electrocatalytic CO2 reduction and CO2 batteries face challenges in achieving complete CO2 conversion with high conversion rates and Faradaic efficiency simultaneously. Existing systems compromise one for the other with incomplete CO2 conversion and inefficiencies, hindering practical applications. This perspective highlights state‐of‐the‐art progress,

Shedding Light on Common Misinterpretations in Photocatalyst Characterization

open access: yesAdvanced Energy Materials, EarlyView.
For heterogeneous semiconductor‐based photocatalysts, Marschall et al. highlight common misconceptions in material synthesis, characterization, and performance evaluation, together with detailed explanations on how to avoid them. The guidelines thus presented can help to improve reporting of photocatalyst performance in environmental applications, such

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 ...

Decoding Short‐Range Order in Amorphous Two‐Dimensional Nanosheets for Efficient and Durable Ampere‐Level Seawater Electrolysis: A Case Study of Amorphous Ni(OH)2

open access: yesAdvanced Energy Materials, EarlyView.
This work uncovers the atomic‐scale origins of exceptional HER performance in amorphous Ni(OH)2 nanosheets by combining atom probe tomography, DFT simulations, and operando spectroscopy. We identify distinct short‐range‐order motifs that accelerate water dissociation, proton transport, and hydrogen adsorption. Embedding Pt single atoms further enhances

Aqueous Lithium Hydroxide Chemistry Based on Hierarchically Assembled Hydrogenated Borophene/Cobalt‐Nickel Compounds for Rechargeable High‐Performance Supercapattery

open access: yesAdvanced Energy Materials, EarlyView.
Aqueous lithium‐ion storage has been demonstrated using a hierarchically assembled hydrogenated borophene/cobalt‐nickel compound as a supercapattery electrode. Reducible hydrogenated borophene generates undercoordinated oxygen, which is redox‐active for lithiation and hydrogenation during the discharging process following the lithium hydroxide ...

Electrocatalytic Nitrate Reduction to Hydroxylamine: Breaking the Activity‐Selectivity Trade‐Off by Designer Bifunctional Metal‐Organic Frameworks

open access: yesAngewandte Chemie, EarlyView.
A bifunctional metal‐organic framework (MOF) catalyst with dual active sites is developed for enabling NH2OH electrosynthesis via NitRR with both high selectivity and activity. ABSTRACT Electrocatalytic nitrate reduction reaction (NitRR) offers a promising route for hydroxylamine (NH2OH) synthesis under ambient conditions.
