                         polyol-mediated process. Four different polyols were used 
                         (diethylene glycol, triethylene glycol, tetraethylene glycol, and 
                         1,2-propanediol) and four different quantities of water (0 mL, 1 
                         mL, 10 mL, 30 mL, with a total volume of 80 mL of solution). 
                         Series of bulk and alumina-supported materials were prepared. 
                         Different structural and textural properties were obtained, 
                         depending on polyol type and hydrolysis ratio. After thermal 
                         treatment at 1000 °C, alumina-supported materials were evaluated 
                         in a lab-scaled fixed bed reactor. Despite a low conversion of 
                         methane due to a low content of active phase AlNbO4, they 
                         presented a high selectivity to syngas (a mixture of H2 and CO) 
                         during the first few seconds of reaction with CH4, indicating a 
                         high selectivity towards chemical-looping reforming process.",
