“…Among the materials studied, γ-Al 2 O 3 is one of the best (Massa et al, 2009). Other support materials, such as silica (Njiribeako et al, 1978), activated carbon (Brainer et al,2014), pillared clay (Carriazo et al, 2005), TiO 2 (Dükkancý and Gündüz, 2009), MCM-41 (Eimer, 2006), ZSM-5 (Valkaj et al, 2007), Ce and Ce-Zr oxides (Nousir et al, 2008), γ-Al 2 O 3 -CeO 2 (Balzer et al, 2014) and polymeric membranes (Molinari at al., 2009), are promising materials and are being increasingly used as catalytic oxidation supports.…”
