Fluorine-enhanced Pt/ZSM-5 catalysts for low-temperature oxidation of ethylene
The low-temperature oxidation of ethylene (C 2 H 4 ) is of critical importance in some specific places and environments such as refrigeration storage, but the catalyst stability needs to be further improved. The microporous Pt/ZSM-5 catalyst prepared in this study exhibited excellent catalytic perfo...
