This system can be operated under mild conditions [weakly basic solution (0.046 mol L −1 NaOH) below 100 °C] without the use of an additional organic solvent. Long-term continuous hydrogen production from a methanol–water solution catalyzed by the anionic iridium complex was also achieved. 最大で84%のH2 yield がでる (TON 160)。
