Summary: Tetracycline is one of the most widely used antibiotics in human therapy, veterinary applications, and agricultural activities. Its consumption is expected to increase by over 30% by 2030. This review focuses on the recent advancements in photocatalytic degradation of tetracycline using graphitic carbon nitride-based photocatalysts, which offer higher visible light activity, low cost, and non-toxicity. The properties, worldwide consumption, occurrence, and environmental impacts of tetracycline are comprehensively discussed. The occurrence of tetracycline in various water matrices has been confirmed, with a maximum concentration of 54 μg/L. Among different graphitic carbon nitride-based materials, heterojunctions have shown the highest photocatalytic degradation efficiency of 100% with reusability for up to 5 cycles. Photocatalytic membranes are found to be feasible due to ease of recovery and better reusability. The limitations and efficient solutions for graphitic carbon nitride-based wastewater treatment technology are also emphasized in detail.

Summary: The widespread use of antibiotics has led to serious environmental issues, and there is an urgent need for new treatments to remove these substances from wastewater. In this study, a new approach using the NiFe2O4/g-C3N4 heterostructure was proposed to activate peroxymonosulfate (PMS) under visible light (VL) for degradation of tetracycline hydrochloride (TCH) in simulated wastewater. The NiFe2O4/g-C3N4/PMS/VL system effectively removed TCH over a wide pH range and in the presence of various anions commonly found in wastewater. The superior degradation performance of the composite was attributed to the synergistic effect between heterojunction photocatalysis and PMS activation, generating highly oxidizing species that effectively degraded TCH. Additionally, the magnetic properties of the heterostructure facilitated separation and reuse of the photocatalyst.

Summary: Metal-free g-C3N4 has gained attention due to its cost-effectiveness and environmental friendliness. However, the synthesis of efficient g-C3N4 modified materials remains challenging. In this study, N-doped porous thin-walled g-C3N4 nanotubes were successfully synthesized through supramolecular self-assembly and thermal polymerization. The synthesized catalysts exhibited excellent photocatalytic activity in the degradation of tetracycline, which was attributed to their high specific surface area and the formation of midgap states after N doping, facilitating charge separation. Possible pathways and mechanisms were proposed based on the analysis of degradation intermediates and active species.

Summary: In this study, a ternary photocatalyst of S-scheme Bi2MoO6/g-C3N4/sepiolite was synthesized and showed improved visible-light-driven photodegradation activity for tetracycline (TC). The photocatalytic degradation performance of Bi2MoO6/g-C3N4/sepiolite was significantly higher than that of the individual components, Bi2MoO6, g-C3N4, Bi2MoO6/g-C3N4, Bi2MoO6/sepiolite and gC3N4/sepiolite. The enhanced activity was attributed to the synergistic effect between S-scheme Bi2MoO6/g-C3N4 heterojunction and sepiolite, which improved adsorption capacity, visible light response ability, and separation efficiency of photoinduced carriers. The study also investigated the degradation mechanism and pathway of TC, providing insights for the design of ternary natural mineral-based photocatalysts for wastewater treatment.

Summary: In order to prepare g-C3N4 with enhanced photocatalytic activity for tetracycline (TC) removal, KCl was utilized in different mixing conditions with precursors, resulting in the formation of KCl-incorporated heptazine-rich g-C3N4. The improved activity can be attributed to enhanced charge separation, nanojunction formation, and increased number of photoexcited electrons. Further optimization of the KCl mixing conditions and precursor ratio can lead to more effective TC removal through photocatalysis.

Summary: In this research, the effect of temperature on the hydrolysis reaction of recycled aluminum for hydrogen production was evaluated. The study found that the highest production of H-2 occurred at 50 degrees C, with a purity of 93.33%. However, at room temperature, the reaction efficiency was still high, with a production of 660 mL of H-2 in 268 s. The physicochemical characterization of the solid residues showed that they contained aluminum, sodium, and oxygen, with the main crystalline phases being aluminum hydroxide and sodium aluminum oxide hydrate. Overall, the production of H-2 from recycled aluminum at room temperature was found to be a viable option for clean power generation with lower energy consumption and financial costs compared to traditional technologies.

Summary: In this study, (Mg/Al)-doped Ni(OH)(2) was synthesized by a microwave-assisted co-precipitation method and then electrophoretic deposition (EPD) was conducted on ITO-coated glasses under applied voltage for 15 minutes. XRD analysis showed the presence of beta-Ni(OH)(2) and a layered double hydroxide (LDH) structure in the powder samples with different Al3+ content. SEM analysis confirmed the lamellar morphology of the samples. Methanol, ethanol, and isopropanol were tested as dispersing media for EPD, and isopropanol was selected based on zeta potential measurements. XRD analysis of the coatings indicated that LDH structure was preferred, and LDH increased surface coverage by incorporating Al3+ ions into the Ni(OH)(2) structure. These findings have interesting implications for the preparation of doped-metal oxide films using EPD from hydroxide precursors.

Summary: In this study, a cost-effective and straightforward method was developed to upgrade abundant biomass into high-value graphene oxide-like dispersions. By a controlled thermal treatment, two different biomass sources with different lignin content were successfully converted into amphiphilic graphene oxide with the help of air atmosphere and short time. The stability and dispersion states of the obtained dispersions were evaluated, and it was found that polar solvents are more effective in achieving stable dispersions compared to non-polar solvents. The results of this study suggest that this strategy can be a feasible and unique approach to formulate stable dispersions using sustainable graphene-based materials.

Summary: In this study, a novel, facile, environmentally friendly, and low-cost sonochemical method was proposed for the synthesis of Mn-Ce oxides with different Ce loadings. The characterization and catalytic activity measurement of the new materials showed that Mn-Ce oxides prepared by sonochemical method exhibited superior catalytic activity with a T-90 value of 266 degrees C, despite their low surface area. This was attributed to the higher Mn4+ content, as well as improved reducibility and activation of O-lat species as compared to the hydrothermally synthesized catalysts. However, the interaction between Mn2O3 and MnO2 in the hydrothermally synthesized catalysts resulted in greater stability in long-term oxidation reactions.

Summary: This review explores and discusses novel nanoengineering strategies for the synthesis of well-defined g-C3N4 nanostructures. These strategies include exfoliation of bulk material, ionic-liquid assisted synthesis, confinement of nitrogen-rich organic precursors in inorganic salts, use of dynamic gas templates, and design of supramolecular precursors, leading to nano and micrometric morphologies that exhibit outstanding photocatalytic properties. Finally, summary comments and a future perspective on the design of novel g-C3N4 morphologies are noted. This review is expected to provide a comprehensive and timely summary of the morphological control of graphitic carbon nitride, leading to a better rational design that improves its performance in photocatalytic processes.

Summary: Several g-C3N4 samples were synthesized through thermal co-polymerization of melamine and urea precursors, their impact and advantages were analyzed, and the sample with the highest fluorescent emission was chosen for the detection of Ag+, Fe3+, and Cr(VI) species. The characterization of the g-C3N4 samples was conducted using various techniques, and the 10U-g-C3N4 sample showed excellent correlation coefficients (R-2 > 0.988) and limits of detection (LOD) for Fe3+, Ag+, and Cr(VI). The sensing mechanisms for Ag+ and Fe3+ ions were attributed to a photoinduced electron transfer (PET) mechanism, while the detection of Cr(VI) species was associated with an inner filter effect (IFE). The results demonstrate that the co-polymerization route yields better results than the calcination of single precursors, offering a simple synthetic procedure for enhancing fluorescence sensing of metal species.
