A Novel Surfactant Sensitized Fluorescent Sensor for Co(II) Based on Nitrogen Doped Carbon Quantum Dots

Autor: Ouwen Xu, Wei Liu, Xiashi Zhu, Shuyu Wan, Jiawei Li

Publikováno v: Photonic Sensors. 12:152-163

A novel nitrogen-doped carbon quantum dots (N-CDs) were prepared by the microwave irradiation method. The fluorescence quenching effect of Co(II) on the N-CDs was studied in the sodium dodecyl sulfate (SDS) medium and the fluorescence quenching was s

Synthesis of ionic liquid modified metal-organic framework composites and its application in solid-phase extraction: a review

Autor: Shuyu Wan, Xiashi Zhu, Ouwen Xu

Publikováno v: Ionics. 27:445-456

Functional material metal-organic framework (MOF) has unique physical and chemical properties. A new type of composite (MOF@ILs) is synthesized by combining it with ionic liquids, which can be used as an extraction agent for solid-phase extraction. T

A facile green and one-pot synthesis of grape seed-derived carbon quantum dots as a fluorescence probe for Cu(ii) and ascorbic acid

Autor: Jiawei Li, Xiashi Zhu, Ouwen Xu

Publikováno v: RSC Advances. 11:34107-34116

In this study, an on–off–on fluorescence probe for the detection of trace Cu(II) and ascorbic acid (AA) based on biomass-derived sulfur and nitrogen double heteroatom-doped carbon dots (N,S-CDs) was designed. For the first time, the probe (N,S-CD

Ni-MOF Functionalized Carbon Dots with Fluorescence and Adsorption Performance for Rapid Detection of Fe (III) and Ascorbic Acid

Autor: Ouwen Xu, Shuyu Wan, Jing Yang, Hanyang Song, Luzheng Dong, Ji Xia, Xiashi Zhu

Publikováno v: Journal of fluorescence. 32(5)

In this work, an "on-off-on" fluorescent probe based on Ni-MOF functionalized Nitrogen-doped carbon quantum dots (Ni-MOF-NCDs) was developed. Ni-MOF-NCDs was characterized by FT-IR, TEM, SEM, and XPS. The presence of Fe (III) will reduce the fluoresc
