Abstract The exploration of sustainable energy utilization requires the implementation advanced electrochemical devices for efficient conversion and storage, which are enabled by usage cost-effective, high-performance electrocatalysts. Currently, heterogeneous atomically dispersed catalysts considered as potential candidates a wide range applications. Compared to conventional catalysts, metal atoms in carbon-based have more unsaturated coordination sites, quantum size effect, strong metal–support interactions, resulting exceptional catalytic activity. Of these, dual-atomic (DACs) attracted extensive attention due additional synergistic effect between two adjacent atoms. DACs advantages full active site exposure, high selectivity, theoretical 100% atom utilization, ability break scaling relationship adsorption free on sites. In this review, we summarize recent research advancement DACs, includes (1) comprehensive understanding synergy atomic pairs; (2) synthesis DACs; (3) characterization methods, especially aberration-corrected scanning transmission electron microscopy synchrotron spectroscopy; (4) energy-related last part focuses great catalysis small molecules, such oxygen reduction reaction, CO 2 hydrogen evolution N reaction. future challenges opportunities also raised prospective section.

Design of Ultra-Stable Solid Amine Adsorbents and Mechanisms of Hydroxyl Group-Dependent Deactivation for Reversible CO2 Capture from Flue Gas

Nano-Micro Letters, Год журнала: 2025, Номер 17(1)

Опубликована: Фев. 28, 2025

Abstract Although supported solid amine adsorbents have attracted great attention for CO 2 capture, critical chemical deactivation problems including oxidative degradation and urea formation severely restricted their practical applications flue gas capture. In this work, we reveal that the nature of surface hydroxyl groups (metal Al–OH nonmetal Si–OH) plays a key role in mechanisms. The polyethyleneimine (PEI) on Al–OH-containing substrates suffers from severe during capture step due to breakage amine-support hydrogen bonding networks, but exhibits an excellent anti-urea feature by preventing dehydration carbamate products under pure regeneration atmosphere. contrast, PEI Si–OH-containing anti-oxidative stability simulated conditions forming robust protective network with Si–OH, obvious step. We also problem PEI-SBA-15 can be avoided incorporation OH-containing PEG additive. Based intrinsic understanding mechanisms, successfully synthesized adsorbent 40PEI-20PEG-SBA-15 demonstrates outstanding retention high capacity 2.45 mmol g −1 over 1000 adsorption–desorption cycles, together negligible loss aging (10% + 5% O 3% H O) one month at 60–70 °C. believe work makes contribution advancement field ultra-stable amine-based materials.
