AI Article Synopsis
- A series of g-CN/SrTiO composites were created using a simple hydrothermal method to effectively degrade tetracycline antibiotics when exposed to visible light.
- The 20% CN/SrTiO composite showed a photocatalytic performance six times better than pure SrTiO and twice that of pristine g-CN, attributed to reduced charge recombination and enhanced light absorption.
- Stability tests and a discussion on the photocatalytic mechanism and charge carrier transfer pathways were also conducted to understand the composite’s performance.
Article Abstract
A series of g-CN/SrTiO (CN/SrTiO) composites with the different mass ratio of g-CN were prepared by facile in situ hydrothermal growth method, which was utilized to degrade tetracycline antibiotics (TC) under the visible light. The obtained samples were characterized by XRD, SEM, XPS, FT-IR, and UV-vis DRS. The photocatalytic performance was also investigated in detail. The obtained 20% CN/SrTiO composite is sixfold of the pure SrTiO and twofold of the pristine g-CN under the visible light irradiation. This impressive performance of the heterojunction is ascribed to the effective restraint of the charge carrier recombination and expanded light absorption region. Moreover, the stability of the composite is also researched in detail. At last, a possible photocatalytic mechanism and charge carrier transfer pathway were further discussed.

Sensitive H sensors play key roles in the large-scale and safe applications of H. In this study, we developed novel ternary Pd-loaded SnO@WO core-shell structures by hydrothermal and reduction methods. The compositions of the optimized ternary core-shell structures (Pd-SW-2) are prepared on the basis of the optimal binary core-shell structures (SW-X) according to the sensing performances to H.

Novel Ce1-xMnxVO4 catalysts prepared via modified hydrothermal synthesis were used in selective catalytic reduction of NO using NH3 (NH3-SCR). The Ce1-xMnxVO4 catalysts displayed optimum NO removal efficiency at 250 oC. Physicochemical properties including crystal type, morphology, particle size, elemental composition, BET surface area, chemical bond, and valence state were studied by XRD, TEM, EDS, N2 adsorption-desorption, Raman spectroscopy, and XPS.

Acetaminophen (AP) is a widely used analgesic and antipyretic drug, but its excessive use poses health risks and contributes to environmental contamination. In response to the need for rapid, accurate, and cost-effective detection methods, we developed a highly sensitive and selective electrochemical sensor for AP. The sensor was based on a composite of UIO-66-NH (UN) and an MXene (TiC).
