Elimination of volatile organic compound by hydroxyapatites derived from waste bone biomass

In present work, altered natural hydroxyapatite (HAp) was extracted from pig bone wastes of different parts (rib, spine, shoulder, forefoot) via well-controlled calcination. The prepared HAp powders were applied as nonnoble metal and green catalyst towards oxidative decomposition of volatile organic compound (VOC) as practical application for the first time. With systemic characterization of the chemical composition, crystal structure, microstructure, surface chemical state, VOC adsorption property of observed HAp powders that extracted under different calcination temperatures, the correlation with resultant catalytic activity was also discussed in detail. The result in present work not only opens new possibility for the efficient removal of VOC by natural HAps but also provide new insights into the recycling of bone waste biomass and development of functional ceramic materials.
