Hydrogen Bubbles: Harmonizing Local Hydrogen Transfer for Efficient Plastic Hydro-Depolymerization

“…Despite the implementation of strategies such as robust mechanical stirring or innovative catalytic reactor designs, , facilitating additional gas–liquid interfaces to enhance hydrogen diffusion into the polymer melt, the intricate nature of hydrogen diffusion persists, particularly at the micron and nanoscale within catalysts. The resolution of these challenges necessitates dedicated efforts on two principal fronts: (1) augmenting H 2 diffusion capacity at the solid–liquid–gas three-phase interface , and (2) amplifying hydrogen migration and storage capabilities on the catalyst surface. − These focused endeavors are integral for navigating the inherent complexities associated with the industrial-scale implementation of hydrogenolysis, playing a pivotal role in effecting the seamless transition of this process from fundamental research to practical applications in industrial settings.…”

Mechanistic insights into NO‒H2 reaction over Pt/boron-doped graphene catalyst

“…H 2 dissociative adsorption was generally considered to be occurring on metal sites, while Hspillover from the metal surface to vicinity of support was usually invoked to describe the reaction mechanism [24][25][26]. However, the involvement of H-spillover in developing the kinetic model for NO-H 2 reaction was rarely reported except the very recent work [27], where Eley-Rideal mechanism was used to describe the reaction route, i.e. gas NO reacts with adsorbed Hspillover.…”
