A novel AgCl-based visible-light photocatalyst through in-situ assembly of carbon dots for efficient dye degradation and hydrogen evolution

Covalent Assembly of Clickable Carbon Nanodots in Water-in-Oil Emulsion for Enhanced Antibacterial Photothermal Therapy

“…Carbon nanodots (CNDs), as leading-edge carbon nanomaterials, have been considered promising candidates for numerous exciting bio-applications owing to their unique chemical properties, high aqueous dispersity, low cytotoxicity, good stability, and excellent biocompatibility. − However, very limited absorption of CNDs in NIR regions hampered their potential applications in PTT. One approach to engineer CND assembly has been explored to attain more attractive photophysical properties. − To the best of our knowledge, previously studied CND assemblies have mainly focused on interparticle noncovalent reactions (e.g., hydrogen bonding or electrostatic interactions). Although these processes can effectively assemble single nanodots to form larger aggregates, they are easily influenced by nonspecifically charged molecules or hydrogen bonds, which are ubiquitous in living organisms.…”

“…Although these processes can effectively assemble single nanodots to form larger aggregates, they are easily influenced by nonspecifically charged molecules or hydrogen bonds, which are ubiquitous in living organisms. Also, the processes are not easily controlled, and random nanoparticle aggregations are possible . Thus, a novel approach to creating a stable and controllable CND assembly is highly desirable.…”

Degradation of rhodamine B photocatalyzed by hydrothermally prepared Pd-doped Bi2MoO6 nanoplates

“…In recent years, a large number of hazardous chemicals in wastewater released from industries can cause serious problems to human beings on Earth. Contaminants such as dyes, pharmaceutical wastes and heavy metals released into water reservoirs are likely to cause cancer and severe health [1][2][3]. Traditional wastewater treatment including bio-degradation, adsorption, ozonation, chlorination, solvent extraction and coagulation are not appropriate for wastewater treatment because they are expensive, non-eco-friendly and low efficiency, including the creation of secondary pollution and serious problems [1,4].…”

“…Thus, its practical application is limited [4][5][6][7]. To utilize solar energy with high efficiency, visible-light-driven photocatalysts which can absorb 48% of the solar spectrum have been intensively investigated [1,[4][5][6][7].…”
