Abstract
Present work lies in the fact that we have demonstrated that highly stable oxygen Nano bubbles (NBs) could be generated and stabilized in a liquid environmental transmission electron microscope (LETEM), using an in house fabricated quasi-2D system. The size of the stabilized NBs varies in the range from 10 to 50 nm, its formation occurred via decomposition of 0.025% hydrogen peroxide on Platinum/CNT nanocomposite. The characterization of growth and long-term stability of NBs has been successfully carried out. In our system, the long-term stability of oxygen NB comes from supersaturation of oxygen molecules and compact arranged of NB. We have also developed the theoretical model derived from Henry's law by which we can predict the stability stage of NBs.
