Modulation of Electronic Structure in Kraft Lignin‐Derived Mo Single‐Atom Catalysts for Optimized Electrochemical Oxygen Reduction

open access: yesAdvanced Science, EarlyView.
Biomass‐derived lignin is used as a sustainable precursor to synthesize Mo single atoms anchored on a nitrogen‐coordinated carbon framework. As the Mo structure transitions from MoC clusters to isolated single‐atom sites, oxygen evolution reaction (ORR) activity progressively improves.

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,

Molecular Bottom‐Up Design of Single‐Site Copper‐Palladium Catalysts for Selective Glycerol Electro‐Oxidation

open access: yesAdvanced Energy Materials, EarlyView.
A bimetallic Cu‐Pd single‐site catalyst for the selective and efficient electrooxidation of glycerol to formate and C3‐products (lactate, glycolate, glycerate) is reported. Experimental and theoretical studies shed light on the catalyst function and reveal that Pd sites facilitate the adsorption of hydroxyl (C‐OH) species which prevents C‐C bond ...

Enhanced Selectivity of Chalcogen Bonding over Halogen Bonding Catalyzed C‐glycosylation Through Differentiated Intermediate Activation

open access: yesAngewandte Chemie, EarlyView.
By harnessing chalcogen bonding (ChB) catalysis, an exclusive access into a highly stereoselective strain‐release C‐glycosylation pathway was discovered. This was surprisingly not replicable by the conceptually similar halogen bonding (XB) catalysis.
