摘要: Abstract In the field of photocatalytic air purification, immobilisation catalyst particles on support surfaces without loss photon efficiency is an important challenge. Therefore, method involving a one-step suspension coating pre-synthesised photocatalysts glass beads was applied. The various benefits are exemplified in gas phase photodegradation ethylene. Coating easy, fast, cheap and offers more efficient alternative to bulk pellets. Furthermore, this procedure allows use porous, catalysts their full potential, as surface area morphology initial powder barely altered after coating, strong contrast pelletising. With technique it became possible study activity commercial titanium dioxide, trititanate nanotubes mixed anatase/trititanate packed bed reactor towards degradation ethylene changing properties. with photocatalyst revealed superior as-prepared nanotubes, compared TiO 2 Aerolyst ® 7710 gaseous phase.
