Microporous and Mesoporous Materials, 2021, 328, pp.111454. ⟨10.1016/j.micromeso.2021.111454⟩
This work deals with the evolution of the mesoporous structure of two silicas MCM-41 and SBA-15 under a 2 MeV electron beam as a function of the dose (0–5 GGy). For a dose of 2 GGy, the pore volume of the two materials decreases significantly by 40
