用自制的气体吸附测试装置进行了在电场作用下镍薄膜吸附氮气和氢气的实验.氮气吸附实验结果表明,充电吸附和放电解吸过程中的电信号可准确表征气体的吸附情况.氢气吸附实验结果表明,电场可以有效提高镍电极对氢气分子的吸附作用,电场强度越大,氢气吸附量越大.在电场强度不变时,提高氢气压力会对氢气吸附量带来较弱的提高.在电场作用下,氢气分子会被极化,从而使氢气分子更容易被吸附,并且有助于形成氢团簇.
The experiments of nitrogen and hydrogen adsorbed on Ni thin film under the action of electric field were carried out by a homemade gas adsorption test device.The experimental results of nitrogen adsorption showed that the electrical signals during charge and discharge desorption can accurately characterize the adsorption of gases.The results of hydrogen adsorption The results show that the electric field can effectively improve the adsorption of hydrogen on the nickel electrode. The larger the electric field strength is, the larger the hydrogen adsorption is. When the electric field is constant, increasing the hydrogen pressure will weaken the hydrogen adsorption. Hydrogen molecules are polarized by action, making the hydrogen molecules more easily adsorbed and helping to form hydrogen clusters.
