Luminescent carbon quantum dots (CQDs) have drawn a great deal of interest in heterogeneous photocatalysis because of their good water dispersibility, exceptional electron transport, and effective light-harvesting capacity, thus enabling the full utilization of the solar spectrum. Surface modification of CQDs is undertaken to improve the optical and electronic properties via surface passivation or functionalization, doping by metal and nonmetal components, and hybrids or nanocomposite synthesis to design CQD-based photocatalysts. CQDs improve the photocatalytic behaviors of some commonly used photocatalysts due to their favorable upconversion photoluminescence and electron transport capabilities. This review aims to present a complete overview of CQDs and recent developments and innovations in the creation of various CQD-based hybrid photocatalysts. Furthermore, the recent significant advances in contaminant degradation are systematically highlighted. Finally, the main problems to be addressed, and the future perspectives to provide a complete picture of CQD-based hybrids.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 10","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review comprehensively summarizes the recent progress in ozone decomposition catalysts, categorizing and evaluating their properties and mechanisms of action. The discussion also includes the catalytic degradation and deactivation mechanisms, with proposed synergistic processes for the simultaneous removal of ozone and volatile organic compounds, and the mechanism for catalytic ozonation for wastewater treatment. Additionally, primary pathways for catalyst deactivation are identified along with protocols for catalyst reactivation.

Preceramic powders obtained from the solution undergo heat treatment at 1400 and 1500 °C in an argon atmosphere. The synthesized powder is subjected to structural and morphological characterization through X-ray diffraction, field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, differential thermal analysis-thermogravimetry, fourier-transform infrared spectroscopy, and raman spectroscopy measurements. Phase analysis reveals the formation of TiB2. Scanning electron microscopy and transmission electron microscopy images clearly show that TiB2 is obtained as a well-defined hexagonal plate-shaped morphology having side lengths of 300–700 nm and thicknesses of ≈12 nm. TiB2 is used as electrode material in both symmetric and asymmetric devices. For asymmetric configuration, graphite, active carbon, and multilayer carbon nanotube powders are used as the counter electrode.

Unlike conventional self-standing EMD electrodes, which limit scalability, this study presents bulk electrodeposition of EMD powder on a lead (Pb) anode. Surface morphology is significantly altered by surfactant presence, though X-ray diffraction and density functional theory analyzes confirms consistent γ-MnO2 crystallography across samples. Galvanostatic charge–discharge at 0.6 A g−1 reveals that TTAB-assisted EMD achieved a specific capacitance of 478.6 F g−1, double that of pristine EMD (232 F g−1), due to improved ion transport and surface area. In contrast, CTAB-assisted EMD shows reduced capacitance (124.6 F g−1), attributed to early micelle formation and immobilization within the MnO2 lattice, which promoted SO42− insertion over surfactant deintercalation. Surfactant critical micelle concentrations and surface activity are key to electrochemical behavior in 1 M Na2SO4.

The different ratios of hydroxypropyl methylcellulose (HPMC) and carboxymethyl cellulose (CMC) effect the structural and functional properties of the films and drug delivery efficiency. A higher HPMC content led to denser networks with smaller pores due to its strong hydrogen bonding capability, while increasing the CMC content facilitated a slower and more sustained drug release. The optimal 30/70 HPMC/CMC ratio was identified as the best formulation, achieving a well-balanced combination of both burst and prolonged drug release phases. Incorporating metal ions as copper, nickel, and iron into levofloxacin complexes enhanced antibacterial activity and altered the release mechanism. The metal-levofloxacin complexes exhibited a biphasic release profile, characterized by an initial burst phase followed by sustained delivery.

The films demonstrated strong stability across all formulations, ensuring consistent performance over time.
