Ru-containing hydroxyapatite (RuHAp) powder was successfully impregnated into sheet composites using a papermaking technique, and its catalytic efficiency was investigated. The RuHAp powder was homogeneously scattered over the fiber-mix networks that had been tailored within the catalyst sheet. RuHAp-containing sheets demonstrated superior performance to RuHAp beads for the selective oxidation of benzyl alcohol to benzaldehyde in a batch reaction process and the efficiency was equivalent to that of RuHAp powder. Catalytic performance was also evaluated in a continuous fixed-bed column reactor and RuHAp sheets showed higher oxidation efficiency than both RuHAp powder and beads. The porous structure of composites seemed to improve the effective transport of benzyl alcohol to RuHAp surfaces which were immobilized within the sheets, resulting in enhanced catalytic performance.
