Carbon dot hybrid porous carbon nanofibers as efficient electrocatalysts for the oxygen reduction reaction

Abstract

Platinum-based materials have been regarded as the state-of-the-art electrocatalysts for oxygen reduction reaction (ORR), but the characteristics of non-earth-abundant, high cost, and vulnerability to poisoning limited their widespread applications. Therefore,...

Carbon quantum dots capped with metal ions for efficient optoelectronic applications

“…Their optical properties are in between those of semiconductor nanocrystals and molecules. 5 Recently, because of their size/surface group tunable optical properties, high quantum yield (QY), and high optical and chemical stability, C-dots have been widely used as efficient building blocks for fabricating optical and electrical devices, including luminescent solar concentrators, 6 photocatalysts, 7–9 biosensors/bioimaging devices 10,11 and anti-counterfeiting devices. 12,13…”

Intermediate aminophenol enables hectogram-scale synthesis of highly bright red carbon quantum dots under ambient conditions

“…CdS and CdSe), due to their wide range of precursor sources, adjustable fluorescence emission, facile synthesis, low toxicity and good biocompatibility. 1–10…”
