摘要: The oxides of the transition metal molybdenum exhibit excellent antimicrobial properties. We present preparation trioxide dihydrate (MoO3 × 2H2O) by an acidification method and demonstrate thermal phase development morphological evolution during after calcination from 25 °C to 600 °C. dehydration material was found proceed in two steps. Microbiological roll-on tests using Staphylococcus aureus, Escherichia coli Pseudomonas aeruginosa were performed exceptional activities determined for anhydrous samples with orthorhombic lattice symmetry a large specific surface area. increase area is due crack formation loss hydrate water at 300 results support proposed mechanism oxides, which based on local acidity as consequence augmented
