Published: May 13, 2024

Abstract TiO 2 photocatalysis has gained attention as a cost‐effective way of degrading contaminants. However, it relies on UV excitation and experiences rapid carrier recombination. To address these drawbacks, novel xylan‐based carbon dots@hydrogenated (CDs@TiO 2‐x ) composited by direct Z‐scheme heterojunction is fabricated visible light‐driven photocatalytic material, which broadens the range light absorption to suppresses recombination photogenerated carriers. The spindle‐shaped CDs@TiO C/N/O/S groups, positive charges, oxygen vacancies its surface, can degrade 89% methylene blue 87% methyl orange within 90 min, 99% rhodamine B 60 min in light. It also eradicates 99.9% E. coli h 97.1% S. aureus 2.5 h. These performances surpass CDs , exhibit advantages similar composite materials. degradation pathways dyes specific antibacterial processes induced ROS are thoroughly investigated through LC‐MS testing related enzyme activity assays. DFT calculations study role vacancies, mechanism, catalytic sites. This developed nanocomposite with applications both dye sterilization, offering insights for multifunctional materials based heterojunction.

Carbon/graphene quantum dots as electrolyte additives for batteries and supercapacitors: A review

Journal of Energy Storage, Journal Year: 2024, Volume and Issue: 85, P. 111040 - 111040

Published: March 1, 2024

Electrolyte is a crucial component in electrochemical energy storage devices (EESDs) such as rechargeable batteries and supercapacitors (SCs). While substantial effort has been directed to engineering the electrodes, fewer but effective continuous efforts have devoted improve devices' performance through modification of their electrolytes. Among these approaches, strategic integration minor amounts additives led formation appropriate solid-electrolyte interphase (SEI) cathode-electrolyte (CEI), well modifying ionic conductivity, preventing dendrite growth, improving charge kinetics. various electrolytes, carbon quantum dots (CDs) graphene (GQDs) emerged favorable options due positive influence on electrolytes for EESDs. These QDs are soluble specific solvents numerous functional moieties allow them act electrolyte polyanions. Furthermore, excellent physiochemical properties make candidates fillers solid-state The excellence verified by characterization methods affirming parameters ion-diffusion kinetics, capacity, resistance. application CDs GQDs EESDs new ruling mechanisms not well-known yet.
