Formic acid, as the simplest carboxylic acid which can be obtained as an industrial by-product, is colorless, low toxicity, and easy to transport and storage at room temperature. Recently, Formic acid has aroused wide-spread interest as a promising material for hydrogen storage. Compared to other organic small molecules, the temperature for formic acid decomposition to produce hydrogen is lower, resulting in less CO toxicant species. Lots of catalysts on both homogeneous catalysts and heterogeneous were reported for the decomposition of formic acid to yield hydrogen and carbon dioxide at mild condition. In this paper, the recent development of mechanism and the material study for both homogeneous catalysts and heterogeneous catalysts are reviewed in detail.

甲酸是可以作为工业副产物获得的最简单的羧酸，无色，低毒且易于在室温下运输和储存。最近，甲酸作为一种有前途的储氢材料引起了广泛的关注。与其他有机小分子相比，甲酸分解产生氢的温度更低，从而导致产生的CO毒物种类更少。据报道在均相催化剂和非均相催化剂上都有许多催化剂在温和条件下分解甲酸产生氢气和二氧化碳。本文综述了均相催化剂和非均相催化剂的机理和材料研究的最新进展。
