Abstract

TiO₂ particles were prepared with various pretreatment temperatures to find optimum electrocatalytic activity in water electrolysis. The morphology and structure of TiO₂ particles were characterized by XRD, N₂ physisoption and SEM analysis. The morphology of TiO₂ particles was significantly affected with calcination temperature. TiO₂ particles pretreated at 200 °C possessed the highest surface areas. The sample showed significant electrocatalytic activity in cyclic voltammograms. Moreover, TiO₂ particles prepared using [Omim][BF₄]+[Hmim][BF₄] were tested with various calcination temperatures. Among the samples, TiO₂ particles after calcination at 100 -C showed the highest electocatalytic performance.
