Abstract

Organic hydrides can store hydrogen via chemical bonding under ambient conditions, enabling the safe storage and transportation of hydrogen gas using the same infrastructure for gasoline. However, in previous research, most organic hydrides have been produced from petroleum, and therefore replacing them with earth-abundant or renewable compounds is essential to ensure sustainability. This study demonstrates dihydrolevoglucosenone (CyreneTM), which is a biodegradable liquid ketone that is produced directly from biomass without pretreatments on an industrial scale, as a new renewable organic hydride. CyreneTM (hydrogen acceptor) is hydrogenated under ambient hydrogen pressure with a highly durable metal complex catalyst to produce 1,6-anhydro-3,4-dideoxy-β-D-threo-hexopyranose (Cyrene-OH, hydrogen adduct). Cyrene-OH stores hydrogen via chemical bonding under ambient conditions, and is dehydrogenated by heating in the presence of the same catalyst to release hydrogen gas and reproduce CyreneTM. This study reports the first attempt to apply compounds, which can be produced directly from biomass on an industrial scale, to organic hydrides, and promotes the development of earth-abundant biomass for sustainable hydrogen storage.

二氢左旋葡萄糖酮（CyreneTM）作为生物衍生的液态有机氢载体。

有机氢化物可以在环境条件下通过化学键储存氢气，从而可以使用与汽油相同的基础设施安全地储存和运输氢气。然而，在以往的研究中，大多数有机氢化物都是从石油中生产出来的，因此用地球上丰富的或可再生的化合物来替代它们对于确保可持续发展至关重要。本研究展示了二氢化左旋葡烯酮（CyreneTM），它是一种可生物降解的液态酮，可直接从生物质中生产，无需进行工业规模的预处理，是一种新的可再生有机氢化物。CyreneTM（氢受体）在环境氢压下，通过高耐久性金属络合催化剂进行氢化，生成 1,6-脱水-3,4-二脱氧-β-D-苏-吡喃糖（Cyrene-OH，氢加合物）。在环境条件下，Cyrene-OH 通过化学键储存氢气，在相同催化剂存在下加热脱氢，释放出氢气，生成 CyreneTM。这项研究首次尝试将可直接从生物质中工业化生产的化合物应用于有机氢化物，促进了可持续储氢的地球丰富生物质的发展。

期刊介绍： ChemPlusChem is a peer-reviewed, general chemistry journal that brings readers the very best in multidisciplinary research centering on chemistry. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies. Fully comprehensive in its scope, ChemPlusChem publishes articles covering new results from at least two different aspects (subfields) of chemistry or one of chemistry and one of another scientific discipline (one chemistry topic plus another one, hence the title ChemPlusChem). All suitable submissions undergo balanced peer review by experts in the field to ensure the highest quality, originality, relevance, significance, and validity.
