FeO x , TiO 2 , and Fe–Ti–O x catalysts were synthesized and used in the catalytic hydrolysis of hydrogen cyanide (HCN). Nearly 100% HCN conversion was achieved at 250 °C over the Fe–Ti–O x catalyst. TiO 2 rutile was detected over TiO 2 , but not over Fe–Ti–O x , which suggested that the interaction between Fe and Ti species could inhibit the TiO 2 phase transition. Furthermore, the interaction between Fe and Ti species over Fe–Ti–O x could promote the selectivity of NH 3 and CO. The mechanism of hydrolysis of HCN over FeO x , TiO 2 , and Fe–Ti–O x can be given as follows: HCN + H 2 O → methanamide → ammonium formate → formic acid → H 2 O + CO.
