Influence of attrition milling on V/Ti catalysts for the selective oxidation of ammonia

- Dry attrition milling can be applied as a dry synthesis of NH3 oxidation catalyst.
- When the TiO2 crystallite size was 15.9 nm, NH3 to N2 conversion was highest.
- (V4+ + V3+)/V5+ ratio and NH3 to N2 conversion have a proportional relationship.
