Mesoporous Alumina as an Effective Adsorbent for Molybdenum (Mo) toward Instant Production of Radioisotope for Medical Use

Mesoporous materials with high surface area and pore volume have attracted significant attention as adsorbents as they can provide extensive reaction sites for molybdenum (Mo) adsorption. In this study, we have prepared mesoporous alumina (MA) materials using a soft-templated approach. By changing the applied calcination temperatures, the mesostructural ordering, surface areas, and crystallinity of the MA materials can be varied. Furthermore, the effects of these parameters on their molybdenum (Mo) adsorption properties have been carefully investigated. The findings in this study will provide guidance for designing effective Mo adsorbents using mesoporous materials toward the next 99Mo/99mTc generator preparation.
