In this study, hydrogen production through the hydrolysis, ethanolysis, and methanolysis reactions of NaBH using adipic acid as a catalyst was investigated for the first time. Adipic acid solutions were prepared with methanol and ethanol at concentrations of 0.1, 0.2, 0.3, 0.4, and 0.5 M. In these reactions, NaBH-MR (methanolysis) and NaBH-ER (ethanolysis) reactions were carried out at 30, 40, and 50 °C with NaBH concentrations of 1.25%, 2.5%, and 5%. Hydrolysis reactions (NaBH-HR) were conducted at 0.1 M under the same conditions. In the ethanolysis and methanolysis reactions at 30 °C, total hydrogen conversion was achieved at 0.3 M, 0.4 M, and 0.5 M. However, in the hydrolysis reactions, total hydrogen production was only obtained at 50 °C. It was observed that in the NaBH-MR and NaBH-ER reactions, total hydrogen conversion could be achieved within 4-5 s. The utilization of adipic acid as a catalyst for hydrogen production from NaBH through ethanolysis and methanolysis reactions is proposed as a highly efficient and fast method, characterized by impressive conversion rates.
在本研究中，首次研究了以己二酸为催化剂，通过硼氢化钠的水解、乙醇解和甲醇解反应制氢。用甲醇和乙醇制备了浓度为0.1、0.2、0.3、0.4和0.5 M的己二酸溶液。在这些反应中，硼氢化钠-甲醇解（NaBH-MR）和硼氢化钠-乙醇解（NaBH-ER）反应在30、40和50℃下进行，硼氢化钠浓度为1.25%、2.5%和5%。水解反应（NaBH-HR）在相同条件下于0.1 M进行。在30℃的乙醇解和甲醇解反应中，0.3 M、0.4 M和0.5 M时实现了总氢转化率。然而，在水解反应中，仅在50℃时获得了总产氢量。据观察，在NaBH-MR和NaBH-ER反应中，4-5秒内即可实现总氢转化率。己二酸作为硼氢化钠乙醇解和甲醇解制氢催化剂的应用被认为是一种高效、快速的方法，具有令人印象深刻的转化率。
