In this study, the nickel boron (Ni–B) catalyst was studied in the microwave environment for hydrogen production from the hydrolysis of a sodium borohydride solution to release H2. The catalytic activity of the Ni–B catalyst was measured by hydrogen production from the hydrolysis of sodium borohydride. The catalytic properties of the Ni–B catalyst in the microwave medium were examined by considering parameters such as NaOH concentration, NaBH4 concentration, catalyst amount, temperature, and microwave power. Thus, the results obtained from the experiments carried out with Ni–B catalyst both in non-microwave and microwave media were compared. In the experiments, under microwave irradiation, the best result was the release of hydrogen gas from the Ni–B catalyst by applying 100 W of microwave energy at 40 °C. Activation energy values were calculated using the reaction rate constants obtained at different temperatures in the nth order kinetic model and the Langmuir - Hinshelwood model.

在Ni-B催化剂存在下和在微波应用下,硼氢化钠溶液的水解

在这项研究中,在微波环境下研究了硼氢化镍溶液水解释放H 2产生氢的镍硼(Ni-B)催化剂。Ni-B催化剂的催化活性是通过硼氢化钠水解产生的氢来测量的。通过考虑诸如NaOH浓度,NaBH 4等参数来检查Ni-B催化剂在微波介质中的催化性能。浓度,催化剂量,温度和微波功率。因此,比较了用Ni-B催化剂在非微波和微波介质中进行的实验获得的结果。在实验中,在微波辐射下,最好的结果是通过在40°C下施加100 W的微波能量从Ni-B催化剂中释放出氢气。使用在n阶动力学模型和Langmuir-Hinshelwood模型中在不同温度下获得的反应速率常数来计算活化能值。
