| Outline of Final Research Achievements |
Hydroxyapatite (HAp, Ca10(PO4)6(OH)2) as one of the most popular functional ceramic materials, has been widely utilized as artificial bone and tooth, filler of high-performance liquid chromatograph and protein remover due to its excellent biocompatibility, ion-exchange and adsorbing ability. We have reported efficient oxidative decomposition of VOC on HAp powder due to its thermal-induced active radicals on surface. Herein, porous HAp with controlled pore structure is fabricated via gel-casting process. The fabricated HAp is applied as VOC decomposition filter and the effect of pore structure on decomposition activity is investigated. Such cost-effective HAp filter developed in this work can be expected as a promising alternative catalyst for VOC decomposition, to compare with the conventional precious metal (Pt, Pb) nanoparticle catalyst which requires both critical dispersity and carrier.

| Academic Significance and Societal Importance of the Research Achievements |
HApは地球上に多く存在するカルシウムとリン酸から構成され、安全かつ安価な材料であり、その材料自身が触媒能を持つ。そのため通常の貴金属触媒のようにセラミックス担体に担持させる必要がなく、HAp材料のみで触媒フィルターを作製することが可能であるなど、環境保全および資源の有効活用のみならず、実用上や経済上の優位性をもつ。高価かつ希少な貴金属を用いず、高効率なガス分解特性を有するHAp触媒が実用化されれば、これまで導入が進まなかった国内外の中小規模施設や環境保護後進国での利用促進による世界的なVOC削減が可能になると考えられる。
