Carbon quantum dots (CQDs) have recently drawn enormous attention due to not only their unique chemical, biological, and optical properties but also because a variety of renewable biomasses are readily utilized as carbon sources in synthesis. This study investigated the synthesis, characterization, functional evaluation CQDs from unbleached mechanical pulp natural lignocellulosic resource. The were synthesized using one-step hydrothermal synthesis with varying temperature, time, consistency. resulting exhibit spherical shape size distribution 9.73 ± 0.82 nm lattice parameters 0.21 0.34 nm, indicating graphite core. photoluminescence spectra showed evident fluorescence characteristics, an emission peak at 435 excitation wavelength 370 nm. as-prepared chemically composed C=C C=O bonds linked hydroxyl carboxyl groups, which typically found lignocellulose-based CQDs. demonstrated antibacterial activity exceeding 99.9% against E. coli lowest concentration 0.75 mg/mL. Demonstrating its antioxidation property, DPPH radical scavenging surpassed 90% more than 40 µg/mL CQD solution.

This study presents a simple and cost-effective approach for synthesizing pyrolytic lignin-based carbon dots (CDPLs) via controlled thermal pyrolysis in water. To the best of our knowledge, this is first time that lignin has been used as precursor dots. The one-pot method produced blue/green fluorescent CDPLs with an average size 34 nm negative surface charge -10.4 mV. characterization techniques revealed optical properties chemical composition CDPLs, fluorescence quantum yield 7.9%, which comparable to those lignin-derived decay lifetime was nanosecond range, typical demonstrates potential using lignin, lignocellulosic byproduct, produce through reproducible method, contributing development sustainable carbon-based nanomaterials.

Abstract Recent years have witnessed a surge in research on aqueous zinc‐ion batteries (AZIBs) due to their low cost, stability, and exceptional electrochemical performance, among other advantages. However, practical manufacturing deployment of AZIBs been hindered by challenges such as energy density, significant precipitation‐related side reactions, slow ion migration, dendritic growth. Addressing these issues enhancing the application necessitates development novel materials. Carbon dots (CDs), with distinctive structure superior properties, represent an innovative class carbon‐based materials broad potential applications for optimizing AZIBs' performance. This study offers comprehensive review how CDs can address aforementioned AZIBs.
