                         metakaolin, amorphous silica and KOH, in the absence of foaming or 
                         saponification agents. The mixture modelling technique was 
                         selected for this study among the Design of Experiments tools, 
                         using surface area and total pores volume as response variables. 
                         The Si/K = 2.46 and Si/Al = 1.37 ratios lead to the optimal 
                         experimental conditions, allowing the formation of a geopolymer 
                         having a specific surface area of 75 m2 /g and total pores volume 
                         of 0.28 cm3 /g. The pores had a bimodal pore size distribution (7 
                         and 20 nm). In spite of its amorphous nature, this structure is 
                         similar to zeolites in terms of ion exchange and metal ions 
                         accommodation. Therefore, this study envisages its application as 
                         a catalyst support.",
