Catalytic applications of carbon dots

Premier, Progress and Prospects in Renewable Hydrogen Generation: A Review

“…Renewable hydrogen might be produced through a process known as solar water splitting, which breaks down water molecules into hydrogen and oxygen. The use of commonly available, nonhazardous components, along with exceptional energy output and versatility makes solar water splitting an appealing technique [52,53]. Solar water splitting is powered by the generation of electrons and holes, which occur when semiconductor materials absorb sunlight.…”

O2-Generating Fluorescent Carbon Dot-Decorated MnO2 Nanosheets for “Off/On” MR/Fluorescence Imaging and Enhanced Photodynamic Therapy

“…Currently, photosensitizers commonly used in clinical PDT belong to a class of chemicals called porphyrinuria, which are limited in use due to their hydrophobicity, lack of targeting, and relatively low ROS production efficiency. , Based on this, photosensitive nanoagents have been widely developed because of their excellent properties such as adjustable optical properties, strong photobleaching resistance, easy target modification, and good biocompatibility . Among them, carbon dots (CDs), as a new type of fluorescent nanomaterials, have become a promising candidate for fluorescence imaging photosensitizers due to their unique valence band, broad excitation spectra, tunable wavelength, and electron/hole pairs that generate singlet oxygen under illumination conditions. , In addition, the unique photochemical properties, superior biocompatibility, easy surface functionalization, and low toxicity of CDs provide favorable conditions for their application in tumor PDT. , As mentioned earlier, excessive GSH in solid tumors can consume oxygen (O 2 ) produced by PDT drugs, and the hypoxic environment of the tumor exacerbates this situation . To achieve a balance between high tumor accumulation efficiency and rapid clearance from the body after treatment, it is necessary to develop a new CDs-based multifunctional nanosystem that not only enhances the cell uptake of photosensitizers but also reduces GSH levels in cancer cells and improves tumor hypoxia.…”
