Calculation method for TOFThe total turn-over frequency (TOF) reported in this work was an apparent TOFvalue based on the number of metal (Ir Ni) atoms in catalysts, which was calculatedfrom the equation as follows:TOF nH2nmetal·tWhere nH2 was the mole number of generated H2, nmetal was the total molenumber of Ni and Ir in catalyst and t was the completed reaction time in hour.S17

Biographies A biography gives facts about a person’s life. It is not written by the subject of the book but by an author who has done their research and knows a great deal about that person. Biographies are written in the third person and can be written about someone who is no longer alive. A biography is a life story written in chronological order. It can include information about when and .
