PEREZ-VIDAL, H. et al. Co/SBA-15 modified with TMB in the degradation of phenol. J. appl. res. technol [online]. 2018, vol.16, n.5, pp.422-436. ISSN 2448-6736.

Mesoporous materials like SBA-15 offer excellent properties such as catalyst support adsorbent due to its textural characteristics and their surface chemistry. The main objective of this study was to support cobalt (20 % w) in the type ordered mesoporous material SBA-15 and expand the pore size with the introduction of a "blowing agent", such as f ,3,5-trimethylbenzene (TMB), to be evaluated in the degradation of phenol. By its physicochemical characterization, it was confirmed that this is an ordered mesoporous material with two-dimensional hexagonal structure (p6mm) with high specific área, narrow pore distribution and typical morphology of this material. The pore size of SBA-f5 has been extended to 19 nm by the addition of cosolvent organic molecules (TMB) and the partióle size of cobalt decreased from 18.8 nm in SBA-15 to 6.4 nm on average by supporting it in SBA-15 modified with TMB; this property seems to confer the material be more selective in the conversión of C02, which is the reason why it has greater activity for the degradation of phenol.
