Surface chemistry and catalytic activity in H₂O₂ decomposition of pyrolytically fluoralkylated activated carbons

Abstract

Modification of AC with C2H2F4 (F4) or C2HF5 (F5) in the temperature range of 400–800 °C with the formation of up to 3 mmol g−1 of chemisorbed fluorine in the form of fluoroalkyl CF3 and CF2 groups and semi-ionic C–F forms.
