Isomer‐Effects of Aminophenol Decorated Gold Nanoclusters for H₂O₂ Photoproduction via Two‐Step One‐Electron Oxygen Reduction Reaction

Small, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 9, 2025

Abstract Gold (Au) nanoclustersare promising photocatalysts for biomedicine, sensing, and environmental remediation. However, the short carrier lifetime, inherent instability, unclear charge transfer mechanism hinder their application. Herein, Au nanoclusters decorated with three different isomers of o‐Aminophenol, m‐Aminophenol, p‐Aminophenol are synthesized, namely o‐Au, m‐Au, p‐Au, which achieve efficient hydrogen peroxide (H 2 O ) photoproduction through two‐step one‐electron oxygen reduction reaction (ORR). The interfacial kinetics photocatalytic process in this system investigated detail, which, isomer‐effects aminophenol definitely elucidated by combining transient photovoltage (TPV), potential scanning (TPS), photo‐induced current (TPC) tests. pathway p‐Au is confirmed to be same TPC. Although conduction band values essentially under working conditions, surface effective charges (n e both m‐Au higher than that o‐Au. In addition, has a stronger adsorption capacity faster ORR rate. Thus, manifests highest activity H photoproduction. This work shows new way ‐ situ study on distribution photocatalysts.

Carbon Dots with Charge Storage Ability Promote the Red Emission of TFB via Carrier Secondary Injection

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 5, 2024

Dual-emission light-emitting diodes (DEDs) have great promising applications in medical imaging, optical communication, data storage, and three-dimensional display. The precise material design advanced packaging technology for the construction of DEDs are still key challenges practical application. We demonstrate a straightforward strategy to construct that deviates from traditional approaches, utilizing commercially available luminescent poly(9,9-dioctylfluorene-co-N-(4-(3-methylpropyl))diphenylamine) (TFB) carbon dots (CDs). In DEDs, mixture CDs TFB was used as layer, which exhibits dual-wavelength emission located at 436 632 nm, respectively. Notably, CDs, with charge storage ability, can store interfacial charges, reinject carriers into TFB, then facilitate long-wavelength (632 nm) TFB. This work provides new way fresh through CD-based transport process.
