Description:

We demonstrate extracting hydrogen into bubbles on hBN via plasma assistance. By adapting this method, bubbles filled with hydrogen molecules can be obtained in controllable diameters. Morphology of the bubble structure on hBN surfaces were carefully characterized by optical microscopy, AFM and Raman spectroscopy. It is found that the bubbles can stand thermal treatment in air even at 800 ℃ . The penetrating depth of atomic hydrogen was determined by measuring the step height of ruptured bubbles. The results reveal that pristine hBN, even its multilayer, can be transparent to atomic hydrogen while impermeable to hydrogen molecule. The work demonstrated here exhibits an effective way to extract hydrogen from gaseous compounds or mixture containing hydrogen.
