Hydrogen is of fundamental importance for the construction of modern clean‐energy supply systems. In this context, the catalytic dehydrogenation of formic acid (FA) is a convenient method to generate H₂ gas from an easily available liquid. One of the issues associated with current catalytic dehydrogenation systems is insufficient stability. Here, we present a robust and recyclable system for FA dehydrogenation by combining a ruthenium 1,1,1‐tris(diphenylphosphinomethyl)ethane complex and aluminum trifluoromethanesulfonate (Al(OTf)₃). This robust system allows steady H₂ production under pressure and recycling for an additional 14 runs without any apparent loss of activity (turnover frequencies up to 1920 h⁻¹, turnover numbers up to 20 000). Notably, the catalyst can also be used for the dehydrogenation of formates and the reverse hydrogenation of bicarbonates and CO₂.

通过有效的钌催化甲酸脱氢制氢

氢对于建设现代清洁能源供应系统至关重要。在这种情况下，甲酸（FA）的催化脱氢是一种从易得的液体中生成H ₂气体的便捷方法。与当前的催化脱氢系统相关的问题之一是稳定性不足。在这里，我们通过结合钌1,1,1-三（二苯基膦甲基）乙烷络合物和三氟甲磺酸铝（Al（OTf）₃）提出了一种健壮且可回收的FA脱氢系统。这个强大的系统允许在压力下稳定产生H ₂，并可以再循环14次而没有任何明显的活动损失（周转频率高达1920 h ^-1，营业额高达2万）。值得注意的是，该催化剂还可以用于甲酸酯的脱氢以及碳酸氢盐和CO ₂的逆氢化。
