Summary: Polymeric carbon nitride (PCN) is a sustainable, metal-free semiconductor that has been studied for its potential in photoelectrochemical (PEC) water splitting. However, the amorphous nature of the polymer limits the charge transfer along the films, thus affecting its performance. In this study, the researchers successfully incorporated gradient concentration of cobalt disulfide (CoS2) into PCN films, resulting in improved charge transfer and enhanced performance for PEC water oxidation.

Summary: This study investigated the hydrogen evolution reaction and photodegradation of Rhodamine B dye using urea-based polymeric carbon nitride (PCN) as a photocatalyst. Different properties of PCN were found to be crucial depending on the reaction type, with the highest efficiency in hydrogen evolution observed due to superior charge transport and charge lifetime properties of PCN. Meanwhile, the photocatalytic degradation of RhB was most effective when the catalyst exhibited the highest specific surface area, despite lower charge transport and charge carrier properties.

Summary: The synthesis of a CoWO4/ZnWO4 p-n heterojunction and its application in the photocatalytic removal of RhB has been reported. The characterization of the photocatalysts confirmed the successful attachment of ZnWO4 nanoparticles to the CoWO4 nanosheets. CZW-3, prepared with a CoWO4/ZnWO4 ratio of 1:3, exhibited the highest photocatalytic activity, degrading RhB at a rate of 93% over 40 min, which is approximately 1.3-fold higher than pure ZnWO4. The formation of p-n heterojunctions, which enhance the transmission of photogenerated carriers, is primarily responsible for the observed high photocatalytic activity. During the degradation process, center dot O-2(-) was identified as the most important reactive species. Furthermore, a plausible photocatalytic mechanism has been proposed.

Summary: In this study, a twisty C-TiO2/PCN (CNT) S-scheme heterojunction was fabricated and utilized for the degradation of ciprofloxacin (CIP) through ultrasonic vibration and visible light irradiation. The nitrogen-rich twisty polymeric carbon nitride (PCN) not only induced a non-centrosymmetric structure with enhanced polarity for better piezoelectric effect, but also provided abundant lone pair electrons for promoting n -> pi * transition during photocatalysis. The hybridization with C-TiO2 particles enabled the construction of S-scheme heterojunction in CNT. Under the synergistic effect of ultrasonic vibration and visible light irradiation, the reaction rate constant of CIP degradation by CNT was significantly increased, demonstrating its potential as an efficient and stable approach for environmental remediation.

Summary: Metal-organic frameworks (MOFs) and covalent-organic frameworks (COFs) have attracted significant attention as highly crystalline advanced permeable materials with large surface area, ordered pores/channels, and controllable structure. However, their low structural stability and electrical conductivities limit their applications in photocatalysis and energy storage/conversion. Extensive research has focused on maximizing their advantages and overcoming these limitations. This review article provides a background and timeline of COF/MOF development, discusses synthetic procedures, recent achievements, and milestones in CO2 reduction, hydrogen production, lithium-ion batteries, and supercapacitors, and explores the challenges and future prospects for high-performance COF/MOF materials in photocatalysis and electrochemical energy storage.

Summary: The primary concerns in optimizing the photocatalytic activity of graphitic carbon nitride (g-C3N4) are enhancing visible light absorption and charge isolation. Introducing benzisothiazolinone (BIT) monomer with electron-withdrawing capabilities into g-C3N4 framework through copolymerization process improves its optical, electronic, conductive, and photocatalytic properties. Integration of BIT monomer causes delocalization of the & pi;-conjugated configuration in g-C3N4, leading to substantial modifications in its molecular electronic arrangement, band gap, and surface area, while increasing electron-hole pairs under visible light (& lambda; = 420 nm). As a result, the optimized g-C3N4/BIT10.0 sample exhibits significantly higher hydrogen (H2) and oxygen (O2) evolution compared to pure g-C3N4 sample, making it suitable for organic photosynthesis, photoreduction of CO2, and H2O2 generation.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
