氢释放：一种有吸引力的可逆氢存储应用方法是基于甲酸的分解。在三烷基胺存在下，铁钳形络合物催化高效和选择性地从甲酸中释放氢。在40℃下，循环频率高达836h⁻？，循环次数高达100,000次，基于实验和计算数据，提出了一种包括明确定义的中间体的机理。
Hydrogen liberation: An attractive approach to reversible hydrogen storage applications is based on the decomposition of formic acid. The efficient and selective hydrogen liberation from formic acid is catalyzed by an iron pincer complex in the presence of trialkylamine. Turnover frequencies up to 836 h⁻¹ and turnover numbers up to 100,000 were achieved at 40 °C. A mechanism including well-defined intermediates is suggested on the basis of experimental and computational data.
