Formic acid (FA) is a chemical being able to be produced from renewable resources such as CO₂ and carbohydrates, and it is regarded as a promising sustainable liquid hydrogen source. Meanwhile, it provides acidity that is also desired in the hydrolytic transformation of biomass feedstocks. In this review, a few examples of FA-aided catalytic conversion of biomass feedstocks including lignin, cellulose and chitin are discussed, with an emphasis on the various roles of FA in these transformations. A perspective on the design of efficient catalytic system for this particular process is also presented.

甲酸辅助的生物质增值

甲酸（FA）是一种能够从可再生资源（例如CO ₂和碳水化合物）中生产的化学物质，被认为是一种有前途的可持续液态氢源。同时，它提供了在生物质原料的水解转化中也期望的酸度。在这篇综述中，讨论了FA辅助催化的生物质原料（包括木质素，纤维素和几丁质）催化转化的一些实例，重点介绍了FA在这些转化中的各种作用。还介绍了针对该特定过程的高效催化系统设计的观点。
