Prototype of Hybrid Recycling Materials Reusable Organism Resources and Photocatalysis

Abstract

A prototype of hybrid recycling materials was made by conjugating a charcoal-sheet or -board with TiO₂ photocatalyst. Sheet or board was constructed with a charcoal powder processed at high temperature (HTCP), an adhensive of organism, and several agricultural or industrial waste organism resources as a binder.
A sheet or board to which photocatalysis of normal-temperature dry type was applied, photo-resolution of ethylene gases (EG) was exhibited to be 15% for sheet and 32-45% for board within 0.5-1.5 hour. An improved photocatalysis synthesized with a hydroxyapatite was applied to the HTCP sheet to prevent from the photo-decomposition of the organic binder, but photo-resolution of EG was low.
