The invention discloses a transition metal iridium complex photocatalyst and a preparation method and application thereof.The molecular formula of the transition metal iridium complex photocatalyst is C36H26F14IrN4P. The synthesis method of the transition metal iridium complex photocatalyst comprises the steps that an intermediate I formed by reacting 2-bromine-5-methylpyridine and 4-fluorophenylboronic acid serves as a ligand and is subjected to a coordination reaction with an iridium compound to form an intermediate II, and then the intermediate II and a ligand 4, 4 '-dibromo-5-methylpyridine compound are subjected to a reaction to form the transition metal iridium complex photocatalyst. The preparation method comprises the following steps: reacting 5, 4-bis (trifluoromethyl)-2, 2-dipyridyl or 5, 5-bis (trifluoromethyl)-2, 2-dipyridyl to obtain an intermediate III, and finally reacting the intermediate III with an ammonium hexafluorophosphate aqueous solution. Although the synthesis steps of the photocataly
