AI Article Synopsis

  • Barium phosphate (Ba(PO)) shows promise as a photocatalyst due to its stability and versatility, although its use in this field is not widely documented.
  • Researchers optimized the synthesis of Ba(PO) nanoflakes through sol-gel and hydrothermal methods, followed by extensive physicochemical analyses to characterize the material.
  • Results indicate that Ba(PO) nanoflakes can effectively degrade pollutants such as rhodamine B, with the sol-gel method producing a more stable photocatalyst over multiple regeneration cycles, highlighting its potential for various photocatalytic applications.

Article Abstract

Barium phosphate (Ba(PO)) is a class of material that has attracted significant attention thanks to its chemical stability and versatility. However, the use of Ba(PO) as a photocatalyst is scarcely reported, and its use as a photocatalyst has yet to be reported. Herein, Ba(PO) nanoflakes synthesis is optimized using sol-gel and hydrothermal methods. The as-prepared Ba(PO) powders are investigated using physicochemical characterizations, including XRD, SEM, EDX, FTIR, DRS, -, LSV, Mott-Schottky, and EIS. In addition, DFT calculations are performed to investigate the band structure. The oxidation capability of the photocatalysts is investigated depending on the synthesis method using rhodamine B (RhB) as a pollutant model. Both Ba(PO) samples prepared by the sol-gel and hydrothermal methods display high RhB photodegradation of 79% and 68%, respectively. The Ba(PO) obtained using the sol-gel process exhibits much higher stability under light excitation after four regeneration cycles. The photocatalytic oxidation mechanism is proposed based on the active species trapping experiments where O is the most reactive species. The finding shows the promising potential of Ba(PO) photocatalysts and opens the door for further investigation and application in various photocatalytic applications.

Article Synopsis
  • The study aimed to evaluate the flexural strength of dental adhesives by testing different combinations of photoinitiators in their formulation.
  • Six groups of adhesive samples were created using specific photoinitiators and co-initiators, and the flexural strength was measured using a three-point testing method.
  • Results showed that adhesives containing BAPO and DPIHFP had significantly higher flexural strength than those with CQ and DMAEMA, indicating that these alternative photoinitiators can enhance the performance of dental adhesives.
