Up-Conversion Fluorescence of Phosphorous and Nitrogen Co-Doped Carbon Quantum Dots (CDs) Coupled with Weak LED Light Source for Full-Spectrum Driven Photocatalytic Degradation via ZnO-CDs Nanocomposites

In order to achieve efficient, green, and low-cost photocatalysts, carbon materials are highly desirable alternatives to other sensitizers such as; dyes and chalcogenide quantum dots. In this paper, we describe green synthesis of phosphorous and nitrogen co doped carbon quantum dots (CDs) from a low...

In this paper, we describe green synthesis of phosphorous and nitrogen co doped carbon quantum dots (CDs) from a low-cost source. The CDs were used as photosensitizers to enhance the visible-NIR driven photocatalytic degradation of organic compounds under weak LED light illumination as an energy efficient light source. The CDs were highly fluorescent and exhibit excitation wavelength independent fluorescence. Electrochemical measurements of CDs were performed to assess the conduction and valences bands. Nanocomposites ZnO-CDs, interestingly, the CDs as a photosensitizer showed dramatic catalytic enhancement, as 80% of methylene blue was degraded under irradiation with a weak LED white light, visible to near IR light, for 10 h. While ZnO under same circumstances, could remove only 10%. The enhancement mechanism in addition to transfer of photoelectrons from the conduction band of CDs to the conduction band ZnO, could also be related to up-conversion properties of CDs, increase the absorptivity of the light. The presented finding showed that low cost source of carbon was used to make efficient nanocomposite photocatalyst for degradation of organic wastes. Graphical Abstract

In this paper, we describe green synthesis of phosphorous and nitrogen co doped carbon quantum dots (CDs) from a low-cost source. The CDs were used as photosensitizers to enhance the visible-NIR driven photocatalytic degradation of organic compounds under weak LED light illumination as an energy efficient light source. The CDs were highly fluorescent and exhibit excitation wavelength independent fluorescence. Electrochemical measurements of CDs were performed to assess the conduction and valences bands. Nanocomposites ZnO-CDs, interestingly, the CDs as a photosensitizer showed dramatic catalytic enhancement, as 80% of methylene blue was degraded under irradiation with a weak LED white light, visible to near IR light, for 10 h. While ZnO under same circumstances, could remove only 10%. The enhancement mechanism in addition to transfer of photoelectrons from the conduction band of CDs to the conduction band ZnO, could also be related to up-conversion properties of CDs, increase the absorptivity of the light.

In this paper, we describe green synthesis of phosphorous and nitrogen co doped carbon quantum dots (CDs) from a low-cost source. The CDs were used as photosensitizers to enhance the visible-NIR driven photocatalytic degradation of organic compounds under weak LED light illumination as an energy efficient light source. The CDs were highly fluorescent and exhibit excitation wavelength independent fluorescence. Electrochemical measurements of CDs were performed to assess the conduction and valences bands. Nanocomposites ZnO-CDs, interestingly, the CDs as a photosensitizer showed dramatic catalytic enhancement, as 80% of methylene blue was degraded under irradiation with a weak LED white light, visible to near IR light, for 10 h. While ZnO under same circumstances, could remove only 10%. The enhancement mechanism in addition to transfer of photoelectrons from the conduction band of CDs to the conduction band ZnO, could also be related to up-conversion properties of CDs, increase the absorptivity of the light. The presented finding showed that low cost source of carbon was used to make efficient nanocomposite photocatalyst for degradation of organic wastes.

title_auth	Up-Conversion Fluorescence of Phosphorous and Nitrogen Co-Doped Carbon Quantum Dots (CDs) Coupled with Weak LED Light Source for Full-Spectrum Driven Photocatalytic Degradation via ZnO-CDs Nanocomposites
abstract	In order to achieve efficient, green, and low-cost photocatalysts, carbon materials are highly desirable alternatives to other sensitizers such as; dyes and chalcogenide quantum dots. In this paper, we describe green synthesis of phosphorous and nitrogen co doped carbon quantum dots (CDs) from a low-cost source. The CDs were used as photosensitizers to enhance the visible-NIR driven photocatalytic degradation of organic compounds under weak LED light illumination as an energy efficient light source. The CDs were highly fluorescent and exhibit excitation wavelength independent fluorescence. Electrochemical measurements of CDs were performed to assess the conduction and valences bands. Nanocomposites ZnO-CDs, interestingly, the CDs as a photosensitizer showed dramatic catalytic enhancement, as 80% of methylene blue was degraded under irradiation with a weak LED white light, visible to near IR light, for 10 h. While ZnO under same circumstances, could remove only 10%. The enhancement mechanism in addition to transfer of photoelectrons from the conduction band of CDs to the conduction band ZnO, could also be related to up-conversion properties of CDs, increase the absorptivity of the light. The presented finding showed that low cost source of carbon was used to make efficient nanocomposite photocatalyst for degradation of organic wastes. Graphical Abstract
