The effect of Ga-doping on the structure and performance of vanadium phosphorus oxide catalysts

摘要

The effects of doping vanadium phosphorus oxide (VPO) catalysts with varying amounts of Ga have been investigated. Microreactor measurements demonstrate that doping levels of between 0.1 and 0.5 at% Ga have a highly beneficial effect on the catalytic performance. The microstructural changes induced by the addition of Ga have been monitored by SEM, HREM and EDX analysis and correlated with the catalytic performance measurements.
