CeO₂‐Based Frustrated Lewis Pairs via Defective Engineering: Formation Theory, Site Characterization, and Small Molecule Activation

Small, Journal Year: 2024, Volume and Issue: 20(26)

Published: Jan. 18, 2024

Abstract Activation of small molecules is considered to be a central concern in the theoretical investigation environment‐ and energy‐related catalytic conversions. Sub‐nanostructured frustrated Lewis pairs (FLPs) have been an emerging research hotspot recent years due their advantages molecule activation. Although progress applications FLPs increasingly reported, fundamental theories related structural formation, site regulation, mechanism not yet fully developed. Given this, it attempted demonstrate underlying theory corresponding regulation methods, its activation on using CeO 2 as representative metal oxide. Specifically, this paper presents three principles for constructing surfaces, feasible engineering methods sites are presented. Furthermore, cases where typical (e.g., hydrogen, carbon dioxide, methane oxygen, etc.) activated over analyzed. Meanwhile, future challenges development FLPs‐centered The insights presented may contribute FLPs, which can potentially provide inspiration broader catalysis involving

Periodic Frustrated Lewis Pairs on Bimetallic Oxide Semiconductors for CO₂ Adsorption and Photocatalytic Conversion

ACS Nano, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 17, 2025

Lewis acids (LAs) or bases (LBs) have been recognized as crucial catalytically active sites for enhancing the adsorption and conversion of inert CO2. However, engineering periodic frustrated pairs (PFLPs) on surfaces semiconductor photocatalysts presents significant challenges, synergistic mechanism PFLPs in CO2 photoreduction remains unclear. In this study, we propose a strategy that utilizes oxygen vacancies to engineer dual-metallic bimetallic oxide surfaces. We employ SrNb2O6–x model photocatalyst elucidate effect photoreduction. Within each FLP unit, LA (Sr2+) captures an O atom from while LB (Nb4+) engages interaction with C concurrently facilitates transfer photoinduced electrons adsorbed Thus, PFLPs-enriched surface exhibits ultrahigh low energy barrier CO desorption. Under focused sunlight irradiation, demonstrates nearly 100% selectivity converting at rate 25.5 μmol g–1 h–1. This study method designing metal inorganic surfaces, which could contribute practical implementation
