Hour‐Level Persistent Multicolor Phosphorescence Enabled by Carbon Dot‐Based Nanocomposites Through a Multi‐Confinement‐Based Approach

Small, Journal Year: 2023, Volume and Issue: 20(23)

Published: Dec. 21, 2023

Abstract Hour‐level persistent room temperature phosphorescence (RTP) phenomena based on multi‐confinement carbon dots (CDs) are reported. The CDs‐based system reported here (named Si‐CDs@B 2 O 3 ) can be efficiently synthesized by a simple pyrolysis method compared to the established RTP systems. binding modes of CDs, silica (SiO ), and boron oxide (B deduced from series characterizations including XRD, FT‐IR, TEM characterization. Further studies show that formation covalent bonds between B , SiO CDs play key role in activating preventing its quenching. This is rare example exhibits hourly under environmental conditions. Finally, applications demonstrated for anti‐counterfeiting, long‐duration imaging, fingerprinting. synthetic strategy expected provide strong technical support preparation pave way synthesis future.

Carbon Catalysts Empowering Sustainable Chemical Synthesis via Electrochemical CO₂ Conversion and Two‐Electron Oxygen Reduction Reaction

Small, Journal Year: 2024, Volume and Issue: unknown

Published: Feb. 2, 2024

Abstract Carbon materials hold significant promise in electrocatalysis, particularly electrochemical CO 2 reduction reaction (eCO RR) and two‐electron oxygen (2e − ORR). The pivotal factor achieving exceptional overall catalytic performance carbon catalysts is the strategic design of specific active sites nanostructures. This work presents a comprehensive overview recent developments electrocatalysts for eCO RR 2e ORR. creation through single/dual heteroatom doping, functional group decoration, topological defect, micro‐nano structuring, along with their synergistic effects, thoroughly examined. Elaboration on mechanisms structure‐activity relationships these provided. In addition to directly serving as electrocatalysts, this review explores role matrix support finely adjusting reactivity single‐atom molecular catalysts. Finally, addresses challenges prospects associated designing fabricating providing valuable insights into future trajectory dynamic field.
