| 摘 要： | 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.

| Abstract: | The adsorption behaviors of nitrogen and hydrogen towards nickel screens under various electric fields were studied.A self-made instrument with high voltage supply was used for gas adsorption tests.Signals detected from gas adsorption tests indicate the adsorb behavior during adsorption and desorption processes.Distinctive hydrogen sorption enhancement is obtained by applying an electric field on the samples.The higher the applied electric field strength is,the higher the hydrogen adsorption capacity is ach... |
