Comparative life cycle assessment of the fabrication of visible-light-driven photocatalytic TiO - Carbon dots nanocomposites for wastewater treatment.

TiO nanoparticles are promising photocatalysts due to their oxidizing strength and inertness. However, their inability to efficiently absorb visible light limits industrial applications that could use sunlight. The addition of carbon dots to TiO has been recently shown to have the potential to address this issue by enhancing the visible-light-driven photocatalytic efficiency of the resulting nanocomposites.

Photocatalytic removal of pharmaceutical water pollutants by TiO - Carbon dots nanocomposites: A review.

Pharmaceuticals are becoming increasingly more relevant water contaminants, with photocatalysts (such as TiO) being a promising approach to remove these compounds from water. However, TiO has poor sunlight-harvesting capacity, low photonic efficiency, and poor adsorption towards organic pollutants. One of the emerging strategies to enhance the photocatalytic performance of TiO is by conjugating it with fluorescent carbon dots.

Insight into the hybrid luminescence showed by carbon dots and molecular fluorophores in solution.

Carbon dots have attracted great attention from the research community given their very attractive luminescent properties. However, the recent discovery that some of these properties may result from fluorescent impurities originating from the synthesis process, and not from the carbon dots themselves, constitute a significant setback to our knowledge of these materials. Herein, we proceeded to the study of carbon dots generated from citric acid and urea via a microwave-assisted synthesis, focusing on their analysis by AFM, HR-TEM, XPS, FT-IR, ESI-MS, UV-Vis and fluorescence spectroscopy.

3-Hydroxyphenylboronic Acid-Based Carbon Dot Sensors for Fructose Sensing.

The selective fluorescence sensing of fructose was achieved by fluorescence quenching of the emission of hydrothermal-synthesized carbon quantum dots prepared by 3-hydroxyphenylboronic acid. Quantification of fructose was possible in aqueous solutions with pH of 9 (Limit of Detection L and Limit of Quantification L of 2.04 and 6.
