摘要
甲酸被认为是一种很有前途的氢载体。生物质甲酸可通过氧化分解糖类获得。本研究探讨了在温和的反应条件下,使用异质催化剂从纤维生物糖(一种由通过 β-糖苷键连接的 d-葡萄糖组成的双糖)中生产甲酸的方法。在过氧化氢存在下,使用碱土金属氧化物固体碱催化剂(如 CaO 和 MgO)可在 343 K 下从纤维生物糖中提取甲酸。虽然 CaO 的甲酸产率为 14%,但氧化物本身在反应后会转化为有害的过氧化金属 CaO2。与此相反,氧化镁可以生成甲酸,而不会形成金属过氧化物。使用这些固体碱催化剂很难从纤维生物糖中选择性地合成甲酸,这是因为纤维生物糖很难转化为葡萄糖。使用固体酸和固体碱催化剂的组合,在温和的反应条件下获得了 33% 的甲酸高产率,这是由于固体酸将纤维生物糖定量水解为葡萄糖,然后固体碱将葡萄糖选择性地分解为甲酸。
Conversion of Cellobiose to Formic Acid as a Biomass-Derived Renewable Hydrogen Source Using Solid Base Catalysts.
Formic acid is considered a promising hydrogen carrier. Biomass-derived formic acid can be obtained by oxidative decomposition of sugars. This study explored the production of formic acid from cellobiose, a disaccharide consisting of d-glucose linked by β-glycosidic bonds using heterogeneous catalysts under mild reaction conditions. The use of alkaline earth metal oxide solid base catalysts like CaO and MgO in the presence of hydrogen peroxide could afford formic acid from cellobiose at 343 K. While CaO gave 14 % yield of formic acid, the oxide itself was converted to a harmful metal peroxide, CaO2 after the reaction. In contrast, MgO could produce formic acid without the formation of the metal peroxide. The difficulty in selectively synthesizing formic acid from cellobiose using these solid base catalysts was due to the poor conversion of cellobiose to glucose. Using a combination of solid acid and base catalysts, a high formic acid yield of 33 % was obtained under mild reaction conditions due to the quantitative hydrolysis of cellobiose to glucose by a solid acid followed by the selective decomposition of glucose to formic acid by a solid base.
期刊介绍:
ChemistryOpen is a multidisciplinary, gold-road open-access, international forum for the publication of outstanding Reviews, Full Papers, and Communications from all areas of chemistry and related fields. It is co-owned by 16 continental European Chemical Societies, who have banded together in the alliance called ChemPubSoc Europe for the purpose of publishing high-quality journals in the field of chemistry and its border disciplines. As some of the governments of the countries represented in ChemPubSoc Europe have strongly recommended that the research conducted with their funding is freely accessible for all readers (Open Access), ChemPubSoc Europe was concerned that no journal for which the ethical standards were monitored by a chemical society was available for such papers. ChemistryOpen fills this gap.
