• Photocatalytic decomposition of ethylene on the TiO2-polystyrene spheres

  Open Research Data

  open access

  • B. Tryba
  • P. Rychtowski

  Data contain results from the measurements of the photocatalytic decomposition of ethylene under UV irradiation with using TiO2 coating on the expanded polystyrene spheres (EPS). EPS-SiO2-TiO2 and EPS-TiO2 were used as the photocatalytic beds in the fluidized bed reactor.  Both, stationary and fluidized beds were tested. The comparison of ethylene decomposition...

  - SEPARATION AND PURIFICATION TECHNOLOGY - Year 2017

  Highly photoactive I/TiO2, Pt/I-TiO2 nanocomposites were obtained using a hydrothermal and wet impregnation method. The incorporation of iodine and modification with 0.05 mol% of platinum leads to enhanced photocatalytic activity as compared to singly doped TiO2 due to the presence of impurity energy level in the structure of TiO2. X-ray diffraction, TEM microscopy, UV–Vis spectroscopy, X-ray photoelectron spectroscopy and BET...

  - Catalysts - Year 2021

  In search a hydrogen source, we synthesized TiO2-Cu-graphene composite photocatalyst for hydrogen evolution. The catalyst is a new and unique material as it consists of copper-decorated TiO2 particles covered tightly in graphene and obtained in a fluidized bed reactor. Both, reduction of copper from Cu(CH3COO) at the surface of TiO2 particles and covering of TiO2-Cu in graphene thin layer by Chemical Vapour Deposition (CVD) were...
