N‐Containing Carbon Materials in Metal‐Free and Non‐Noble Metal Liquid Phase Heterogenous Catalysis

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Over 100 examples of non‐noble metal supported on N‐containing and metal‐free N‐containing carbon catalysts are discussed. Particular emphasis is put on how different N‐functionalities influence catalyst performance and stability. Preparation procedures are also examined, with a strong focus on how the heat treatment temperature influences N ...

Electrochemical Deoxygenation Electrolyzers Using an Organic Catalyst

open access: yesAdvanced Sustainable Systems, EarlyView.
Conductive polymers offer a promising metal‐free route for the oxygen reduction reaction (ORR) in deoxygenation electrolyzers. The n‐type polymer demonstrates that BBL catalyzes ORR via a four‐electron pathway with high mass activity. A low‐voltage electrolyzer using BBL‐coated electrodes and catechol as a compensating redox additive efficiently ...

Gas‐ and Liquid‐Phase Catalysts for Solar‐Driven Catalytic Ammonia Decomposition

open access: yesAdvanced Sustainable Systems, EarlyView.
Amid the drive toward carbon‐neutral hydrogen, this review analyzes photocatalytic ammonia decomposition in gas‐ and liquid‐phase systems. It examines catalyst families—TiO2, ZnO, Ru, single‐atom, and antenna–reactor designs. This study summarizes advances in bandgap tuning, active‐site and cocatalyst engineering, photothermal coupling, and machine ...

Ni Single Atoms in Zeolite Beta for Selective Alkyne Hydrogenation

open access: yesAdvanced Sustainable Systems, EarlyView.
Single‐atom Ni in zeolite Beta (Ni1/BEA) selectively remove trace acetylene from ethylene. Ni1/BEA achieve full conversion with ≈89% ethylene selectivity, stable for 24 h without coking, and 12 times higher TOF than prior zeolite‐supported single‐atom Ni catalysts. Na+ exchange suppress Brønsted acid‐catalyzed oligomerization. Under ethylene‐rich feeds,
