摘要

We have been studying the functionalization [1] of waste biomass which is easily available globally and which can be regenerated during a human life cycle. Animals or plants are well known to take in and accumulate elements required for life support. Importantly, their work lowers environmental load and is carried out without the need to introduce expensive raw materials. We succeeded in using fowl droppings to yield biomimetic calcium phosphate compounds that are less crystalline have attracted attention as a potential functional material [2]. In this study, we report the purification technology of the air pollutants such as NOx, SOx, and bacteria, using the synthesised compounds. The calcium phosphate compound has attracted attention as one of the air cleaning materials, e.g., exhaust filters and car ventilation [3], adsorbents or separators of proteins [4], and catalysts [5]. We have investigated the adsorption of NO2, SO2, and bacteria, onto the synthesized calcium phosphate compound. High adsorptive capabilities were observed for all synthesized calcium phosphate compounds (Table 1). Furthermore, the effects of photocatalytic decomposition and antibacterial also been suggested for the synthesized calcium phosphate compounds. Hence, the biomimetic synthesized calcium phosphate compound from fowl droppings which is a disposal resources existing around the world may provide new options as a cheap and highly functional material in clean air technology.
