▎ 摘　　要

The electrochemistry (EC) method was used to synthesize graphene oxide-nickel (GO-Ni) metal organic framework (MOF) that has the thickness of pin-level. The MOF's thermal stability and hydrogen adsorption and desorption capacity were measured by using an optical fiber Mach-Zehnder interferometer (MZI) sensor. This MZI was fabricated by core-offset fusion splicing one section of single mode fiber (SMF) between two SMFs. Experimental results showed that the GO-Ni MOF could be stabilized. even as the environmental temperature reached 125 degrees C. The MOF showed good hydrogen adsorption ability for the the MOF and hydrogen molecules's interactions. (C) 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
