Today, cleaning the environment using photocatalytic technology is one of main research activities. In this study, carbon dots (C-dots) were anchored on oxygen-vacancy-enriched TiO2 quantum (QDs)/TiO2 oxygen vacancies (OVs) a facile procedure. The resultant ternary QDs/TiO2 OVs/C-dots photocatalysts with dot size almost 4.55 nm used for detoxification aqueous solutions containing four antibiotics and three organic dyes as well inactivation two pathogenic bacteria, including Escherichia coli Staphylococcus aureus, upon visible light. degradation constant tetracycline over optimized nanocomposite reached 714 × 10–4 min–1, which was 17.3, 12.1, 2.92 times higher than QDs, OVs, TQDs/TOVs (1:1) materials, respectively. Effective separation electron–hole pairs between QDs OVs counterparts through decorated C-dots by an established S-scheme system reason boosted activity. With regard to growth wheat lentil seeds in treated solutions, it hoped that significant stability could be clean up wastewaters.

Abstract Designing cost‐effective electrocatalysts with fast reaction kinetics and high stability is an outstanding challenge in green hydrogen generation through overall water splitting (OWS). Layered double hydroxide (LDH) heterostructure materials are promising candidates to catalyze both oxygen evolution (OER) (HER), the two OWS half‐cell reactions. This work develops a facile hydrothermal route synthesiz hierarchical MoS 2 @NiFeCo‐LDH @NiFeCo‐Mo(doped)‐LDH electrocatalysts, which exhibit extremely good OER HER performance as witnessed by their low IR‐corrected overpotentials of 156 61 mV at current density 10 mA cm −2 under light assistance. The @NiFeCo‐Mo(doped)‐LDH‐MoS cell achieves voltage 1.46V during light‐assisted electrolysis. Both exhibited exceptional industrially relevant conditions, maintaining 1 A minimal alterations potential performance. experimental computational results demonstrate that doping LDH matrix high‐valence Mo atoms quantum dots improves electrocatalytic activity 1) enhancing electron transfer, 2) making electrocatalyst metallic, 3) increasing number active sites, 4) lowering thermodynamic overpotential, 5) changing mechanism. Overall, this synthesis method design highly stable electrocatalysts.

Lithium-sulfur (Li-S) batteries have emerged as one of the most attractive alternatives for post-lithium-ion battery energy storage systems, owing to their ultrahigh theoretical density. However, large-scale application Li-S remains enormously problematic because poor cycling life and safety problems, induced by low conductivity , severe shuttling effect, reaction kinetics, lithium dendrite formation. In recent studies, catalytic techniques are reported promote commercial batteries. Compared with conventional sites on host materials, quantum dots (QDs) ultrafine particle size (<10 nm) can provide large accessible surface area strong polarity restrict excellent effect enhance kinetics redox reactions, well abundant lithiophilic nucleation regulate Li deposition. this review, intrinsic hurdles S conversion stripping/plating reactions first summarized. More importantly, a comprehensive overview is provided inorganic QDs, in improving efficiency stability batteries, strategies including composition optimization, defect morphological engineering, design heterostructures, so forth. Finally, prospects challenges QDs discussed.
