The correlation between structure and properties in the photodegradation reaction of bismuth oxychloride (BiOCl) was explored this work. Three BiOCl samples with different sizes, morphological structures, defects were prepared through a hydrothermal method experimental manipulation. Their structural comprehensively characterized using X-ray diffraction, scanning electron microscopy, transmission spin resonance, photoelectron spectroscopy, Fourier transform infrared ultraviolet–visible diffuse reflectance photoluminescence. Taking tetracycline hydrochloride (TC-HCl) as probe reaction, we found that high activity could be achieved by decreasing their crystal size thickness, introducing proper structure, assembling nanosheets to get microball structure. Combined radical-scavenge experiments resonance (ESR) spin-trap spectra, conclude ̇O2– dominant reactive oxygen species for degradation reaction. detailed pathway TC-HCl further analyzed liquid chromatography–mass spectrometry. This work explores structure–property provides strategies rational design active photocatalysts water remediation.

Renal-Clearable Biomass-Derived Carbon Dots with Red Fluorescence for Masked Cryptic Kidney Injury Imaging

ACS Applied Bio Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 16, 2025

Masked cryptic kidney injury (MCKI), an early stage of acute (AKI), is challenging to detect and diagnose, especially in the modern context where toxic substances, such as surfactants, are increasingly misused. Consequently, there urgent need for methods visual diagnosis MCKI. In this study, we synthesized environmentally friendly spirulina-derived carbon dots (SpiCDs) using spirulina a biobased raw material through simple hydrothermal process. These SpiCDs, with their ultrasmall size, enable efficient renal clearance. cellular experiments, SpiCDs rapidly entered SDS-damaged cells, facilitating dynamic monitoring cell membrane damage vivo animal experiments demonstrated that were efficiently excreted kidneys began accumulate bladder within 10 min after tail vein injection. The detection red fluorescence urine confirmed metabolic pathway SpiCDs. Furthermore, MCKI model induced by SDS, showed accelerated excretion earlier accumulation bladder, indicating increased sensitivity injury. results suggest provide promising approach MCKI, offering insights into its monitoring.

EcoEnergy, Год журнала: 2025, Номер unknown

Опубликована: Март 4, 2025

ABSTRACT Biomass‐derived carbons are eco‐friendly and sustainable materials, making them ideal for supercapacitors due to their high surface area, excellent conductivity, cost‐effectiveness, environmental benefits. This review provides valuable insights into biomass‐derived carbon modified supercapacitors, integrating both experimental results theoretical calculations. begins by discussing the origins of in including plant‐based, food waste‐derived, animal‐origin, microorganism‐generated sources. Then, this presents strategies improve performance heteroatom doping, functionalization, hybrid composite construction. Furthermore, analyzes functions its pure form as materials. The also explores composites derived from biomass‐based carbon, carbon/MXenes, carbon/MOFs, carbon/graphene, carbon/conductive polymers, carbon/transition metal oxides, carbon/hydroxides, providing a thorough investigation. Most importantly, offers an innovative summary analysis role through calculations, concentrating on four key aspects: energy band structure, density states, electron cloud density, adsorption energy. Finally, concludes future research directions biomass carbon‐based discovery novel tailoring functional groups, fabricating high‐performance exploring ion transfer mechanisms, enhancing practical applications. In summary, exploration sources, functions, mechanisms research.
