We prepared a new three-dimensional, flower-like La-TiO/g-CN (LaTiCN) heterojunction photocatalyst using a solvothermal method. Analysis and characterization were performed by conducting scanning electron microscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, Fourier transform-infrared spectroscopy, ultraviolet-visible spectrophotometry, and nitrogen adsorption and desorption. The prepared g-CN nanosheets could reach 100 nm in size and covered the TiO surface. A tightly bound interface formed between the g-CN and TiO, speeding up the effective transfer of photo-induced electrons. In addition, the incorporation of La reduced the electron-hole recombination efficiency. Consequently, the prepared La-TiO/g-CN composite material exhibited better visible-light catalytic activity than pure TiO.

With the development of electronics, electroplating, printing, and dyeing industries, environmental pollution caused by hexavalent chromium (Cr(VI)) has become increasingly prominent. Skin contact with Cr (VI) can cause allergies or genetic defects, and inhalation can cause cancer, which is a lasting danger to the environment and the human body. Developing effective strategies to monitor Cr(VI) in environmental water or industrial wastewater can evaluate the degree of water pollution and risk warning, thus helping to prevent the spread of Cr(VI) pollution, promote the protection of water resources and the ecological environment, and ensure human safety and sustainable development.

Article Synopsis
  • Extensive use of fossil fuels leads to high CO2 emissions, necessitating the development of eco-friendly energy storage materials.
  • Hybrid supercapacitors (HSCs) are emerging materials that provide quick charging and high capacitance retention, with the current study focusing on a composite of g-CN nanosheets and CoO/CeO heterostructures as effective electrodes.
  • The CoCe/g-CN electrodes demonstrate significantly higher specific capacitance (1088.3 F/g) and impressive stability (96% over 5000 cycles), making them promising options for advanced energy storage solutions.

Copper ions coordination-promoted self-assembly of DNA nanoflowers as cascade catalytic nanoreactor for colorimetric biosensor.

The controllable geometry and multifunctionality of DNA nano-bioreactors hold immense promise for disease diagnosis. Herein, a facile rolling circle amplification (RCA)-based crystallization method has been developed for highly efficient self-assembly of three-dimensional (3D) DNA nano-bioreactors, which show excellent cascade catalytic performance by confining bio-enzyme (glucose oxidase (GOx) used in this case) and copper ions (Cu) in DNA nanoflowers (DNFs) structure. The participation of Cu during the self-assembly process not only endows the nano-bioreactors (designated as GOx/Cu@DNFs) with inspiring peroxidase-like activity but also greatly improves the assembly efficiency and yield via the effective coordination between Cu and RCA-generated long concatemeric DNAs.

Photocatalytic oxygen reduction is considered an economical and green way to produce HO. Graphitic carbon nitride is a common photocatalyst, but its activity is limited by the low specific surface area and the high recombination rate of photogenerated electron-hole pairs. Herein, nanoflowers-like phosphorus (P) and potassium (K) co-doped graphitic carbon nitride (PKCN) is synthesized by co-polymerization of ammonium dihydrogen phosphate and melamine in the mixed molten salt (KCl/LiCl) medium.

Raman scattering, as a vibrational spectrum that carries material information, has no photobleaching that enables long-duration imaging. Raman spectra have very narrow emission peaks, and multiplex Raman imaging can be achieved by using different Raman scattering peak signals. These advantages make Raman imaging widely used in biology, cytology, and medicine, which has a wider range of application scenarios.
