Summary of "Yeast-derived carbon sphere as a bridge of charge carriers towards to enhanced photocatalytic activity of 2D/2D CuWS/g-CN heterojunction."

It is very challenging to fabricate novel, high-efficiency photocatalysts with an enhanced visible light absorption capacity, high charge carrier separation efficiency, and large specific surface area. For this purpose, a yeast-derived carbon (YC) sphere was added as a charge carrier bridge to the 2D-2D CuWS/g-CN heterojunction through a facile hydrothermal method. The YC sphere, as a bridge for electrons, is not only advantageous in inhibiting rapid recombination by electrons, but also remarkably enhances the visible light absorption capacity. Moreover, the YC sphere can also increase the specific surface area and surface roughness, which can enhance the adsorption of pollutant molecules and provide abundant active sites for photocatalytic reactions. The g-CN/YC/CuWS heterojunction showed the best photocatalytic activity for reducing hexavalent chromium Cr(VI) and decomposing tetracycline (TC) under visible light. Meanwhile, the acute toxicity of Daphnia magna (D. magna) gradually decreases with the conversion of Cr(VI) to Cr(III) in solution. In addition, the possible intermediate products and the photocatalytic reaction mechanism are revealed in depth. This work provides a general example for improving the photocatalytic activity of 2D-2D based heterojunctions by introducing a biomass material.

Medical and Biotech [MESH] Definitions

An atom or group of atoms that have a positive or negative electric charge due to a gain (negative charge) or loss (positive charge) of one or more electrons. Atoms with a positive charge are known as CATIONS; those with a negative charge are ANIONS.

Forms to which substances are incorporated to improve the delivery and the effectiveness of drugs. Drug carriers are used in drug-delivery systems such as the controlled-release technology to prolong in vivo drug actions, decrease drug metabolism, and reduce drug toxicity. Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions. Liposomes, albumin microspheres, soluble synthetic polymers, DNA complexes, protein-drug conjugates, and carrier erythrocytes among others have been employed as biodegradable drug carriers.
