Paraformaldehyde was decomposed using an organoiridium complex (1, [Ir(III)(Cp*)(4-(1H-pyrazol-1-yl-κN(2))benzoic acid-κC(3))(H2O)]2SO4) as a catalyst in water to produce H2 and CO2 in a 2 : 1 molar ratio at room temperature. The catalytic cycle is composed of the reduction of 1 by paraformaldehyde under basic conditions to produce formic acid and the hydride complex, which reacts with protons to produce H2. Formic acid further decomposed to H2 and CO2 with 1.
在室温下，使用有机铱配合物（1，[Ir(III)(Cp*)(4-(1H-吡唑-1-基-κN(2))苯甲酸-κC(3))(H₂O)]₂SO₄）作为催化剂在水中分解多聚甲醛，以2∶1的摩尔比生成H₂和CO₂。催化循环由在碱性条件下多聚甲醛将1还原生成甲酸和氢化物配合物组成，该氢化物配合物与质子反应生成H₂。甲酸再与1反应分解为H₂和CO₂。
