ACS Energy Letters, Год журнала: 2024, Номер 9(8), С. 3694 - 3718

Опубликована: Июль 5, 2024

High-entropy materials (HEMs) are typically crystalline, phase-pure and configurationally disordered that contain at least five elements evenly blended into a solid-solution framework. The discovery of high-entropy alloys (HEAs) oxides (HEOs) disrupted traditional notions in science, providing avenues for the exploration new materials, property optimization, pursuit advanced applications. While there has been significant research on HEAs, creative breakthroughs HEOs still being revealed. This focus review aims developing structured framework expressing concept HEM, with special emphasis crystal structure functional properties HEOs. Insights recent synthetic advances, foster prospective outcomes their current applications electrocatalysis, battery, comprehensively discussed. Further, it sheds light existing constraints HEOs, highlights adoption theoretical experimental tools to tackle challenges, while delineates potential directions energy application.

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

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Фев. 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
