Summary: The novel ternary BiOBr/g-C3N4/Ti3C2Tx (BCT-x) hybrids were successfully prepared via the in-situ construction method, and showed improved photocatalytic degradation performance for Tetracycline Hydrochloride (TC-HCl) and Rhodamine B (RhB). The BCT-5 exhibited vintage photocatalytic activity for both TC-HCl and RhB. LC-MS analysis showed that TC-HCl could be degraded into smaller and non-toxic substances by BCT-5. This study provides guidance for advancing the application of photocatalytic technology in water pollutant degradation.

Summary: The self-assembly L-cysteine (L-Cys)-based 2D g-C3N4 nanoflakes showed promising photocatalytic activity for the degradation of Rhodamine B and Tetracycline under visible light irradiation. The enhanced photocatalytic activity was attributed to the mesoporosity, abundant photoexcited electrons, and few structure defects of the nanoflakes.

Summary: In this article, a novel setup treatment using nitric acid vapor to treat g-C3N4 (CN) was reported. The basic structure of CN was not destroyed by the treatment. These adoptive treatments enhanced the photocatalytic performance of CN, leading to the elimination of RhB and TC. Among them, CN-6 exhibited the highest photocatalytic yield for the breakdown of RhB (99% in 20 min). The treatment with nitric acid vapor promoted a blue shift, extended the valence band position, increased the oxidizability of the holes, and improved the dispersion of CN in the aqueous phase, introducing more oxygen-containing functional groups. Thus, it has the potential to be applied for enhancing the photocatalytic activity of CN.

Summary: Graphitic carbon nitride (g-C3N4) has attracted attention as a visible-light-driven photocatalyst for degrading organic dyes and antibiotics. However, its bulk activity is limited due to rapid recombination of electron-hole pairs and low specific surface area. In this study, g-C3N4 nanosheets were prepared through one-step thermal treatment of melamine in the presence of NH4Cl, exhibiting excellent photocatalytic activity and restricted recombination of electron-hole pairs.

Summary: In this study, g-C3N4/diatomite composites were synthesized by mixing melamine and diatomite in hydrochloric acid aqueous solution and calcining the mixture at 550 degrees C for 2 hours. The CN/DE-10 composite exhibited the best photocatalytic performance, degrading over 95% of RhB solution in 50 minutes, with a reaction rate constant 6.4 times that of pure g-C3N4. The enhanced specific surface area, improved light absorption ability, and reduced recombination rate of electrons and holes contributed to the outstanding photocatalytic performance of CN/DE-10.

Summary: Highly effective Z-scheme La-ZnO/GCN nanocomposite (LZG) was synthesized via hydrothermal and ultrasonication methods. Various techniques were used to analyze the prepared samples, including X-ray diffraction (XRD), high-resolution scanning electron microscopy (HRSEM), X-ray photoelectron spectroscopy (XPS), and UV-visible spectroscopy. The results showed that LZG had no secondary phase formation, La ions were present in the host lattice, and La-ZnO nanorods were observed on GCN nanosheets. Higher charge transfer property was observed, leading to enhanced pollutant degradation. The research supports a novel design of nanocomposite for enhancing the degradation of pharmaceutical pollutants by hindering charge recombination.

Summary: A spherical B-g-C3N4/Bi2WO6 heterojunction photocatalyst was synthesized using the hydrothermal coprecipitation method. The study found that B-g-C3N4 was uniformly dispersed on the Bi2WO6 surface, reducing its energy bandgap. The photocatalytic degradation of rhodamine B showed a significant enhancement in the degradation rate for the 1:3 BCN/BWO composite, with a degradation rate 76 times higher than B-g-C3N4 and 7 times higher than Bi2WO6. The proposed photocatalytic degradation mechanism is based on the results of UPS and free radical capture experiments, and the direct Z-type B-g-C3N4/Bi2WO6 heterojunction structure promotes effective carrier separation and oxidation-reduction ability.

Summary: This study successfully synthesized a highly efficient visible-light-driven photocatalyst for hydrogen evolution and H2O2 production by manipulating the electronic band structure and surface properties of g-C3N4. The optimized B, Cs co-doped g-C3N4 nanosheets showed significantly improved hydrogen evolution and hydrogen peroxide production rates, as well as high photooxidation ability. The enhanced photocatalytic performance is attributed to the synergistic effect of co-doping and formation of porous and wrinkled nanosheets, which provide increased accessible reaction sites.

Summary: In this study, novel structures of graphitic carbon nitride (GCN) were designed by controlling the quantity of NHx(x = 1, 2) and C boolean AND N moieties through a facile NaBH4-assisted calcination of supramolecular assemblies of cyanuric acid and melamine (CM complex). These functional groups acted as donor-acceptor (D-A) motifs in the obtained GCN conjugated polymer, forming a biomimetic D-A system. The structurally modified sample (DCN) showed extended electronic delocalization and enhanced exciton dissociation, thanks to the formation of an internal electric field at the molecular scale. Furthermore, the CM complex endowed the structures with an improved surface area and unique coral-like morphology. As a result, the modified sample exhibited a remarkable photocatalytic H2O2 production rate of 351 μmol h-1 g-1, much higher than that of the pristine sample (CN).

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
