WebBubbles can also form within pre-existing gas pockets located in surface cracks and imperfections of solids in a process known as heterogeneous nucleation (Figure 1). Supersaturated gas diffuses into the gas pockets, causing bubble growth and eventual detachment from the solid support. Unlike homogeneous nucleation, significantly less WebSep 8, 2024 · Understanding nanoscopic bubble nucleation and growth is critical to reducing significant losses in efficiency during water electrolysis or photoelectrochemical hydrogen production. Herein, we demonstrate the controlled nucleation and growth of H2 nanobubbles at individual Pt nanoparticles (NPs) via the hydrogen evolution reaction …
