Modulating product selectivity in lignin electroreduction with a robust metallic glass catalyst

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: April 10, 2025

Converting the lignin into value-added chemicals and fuels represents a promising way to upgrade lignin. Here, we present an effective electrocatalytic approach that simultaneously modulates depolymerization hydrogenation pathways of model compounds within single reaction system. By fine-tuning pH electrolyte, achieve remarkable shift in product selectivity, from acetophenone (with selectivity >99%) 1-phenylethanol >99%), while effectively preventing over-hydrogenation. The robust metallic glass (MG) catalyst, endowed with amorphous structure, demonstrates high stability, activity, full recyclability across over 100 consecutive cycles ionic liquid electrolytes. relatively strong affinity MG catalyst for substrate during initial stage, conjunction its weaker binding phenolic product, as progresses, creates delicate balance optimizes adsorption desorption, which is pivotal driving cascade process acetophenone. This work opens versatile upgrading through integrated tandem reactions expands scope design structures.

d-Band Center Regulation Facilitated by Asymmetrical Ligand in the Atomically Dispersed Iron Site toward Promoting Oxygen Electrocatalysis Activities

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: April 22, 2025

The prosperity of aqueous rechargeable Zn-air batteries is hindered by the discontent performance oxygen electrocatalyst in cathode. An important catalyst for an atomically dispersed iron atom embedded nitrogen-doped carbon (Fe-NC) material. However, unsuitable binding energy between center Fe and reaction intermediate leads to sluggish rate. regulation electron structure adjusting coordinate one effective solution. Here, we prose substitution nitrogen sulfur atom, who has weak electronegativity can donor so d-band elevated. Thus, Fe-NS active site facilitates fast *OOH adsorption *OH desorption, compared with counterpart Fe-N site. As a result, kinetics accelerated. Fe-NSC good compatibility batteries, affording stable charge/discharge process 1000 h/3000 cycles high voltage tolerance (0.74-0.96 V gap) under 10 mA cm-2. This work brings referential sights modification M-N-C-type catalyst.

Clarifying the Active Structure and Reaction Mechanism of Atomically Dispersed Metal and Nonmetal Sites with Enhanced Activity for Oxygen Reduction Reaction

Advanced Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 24, 2024

Abstract Atomically dispersed transition metal (ADTM) catalysts are widely implemented in energy conversion reactions, while the similar properties of TMs make it difficult to continuously improve activity ADTMs via tuning composition metals. Introducing nonmetal sites into may help effectively modulate electronic structure metals and significantly activity. However, is achieve co‐existence with atoms clarify their synergistic effect on catalytic mechanism. Therefore, elucidating active within atomically metal‐nonmetal materials unveiling mechanism highly important. Herein, a novel hybrid catalyst, coexistence Co single‐atoms Co─Se dual‐atom (Co─Se/Co/NC), successfully synthesized exhibits remarkable performance for oxygen reduction reaction (ORR). Theoretical results demonstrate that Se can charge redistribution at sites. Furthermore, between single‐atom further adjust d‐band center, optimize adsorption/desorption behavior intermediates, finally accelerate ORR kinetics. This work has clearly clarified shows great potential nanomaterials storage applications.
