Unexpectedly spontaneous water dissociation on graphene oxide supported by copper substrate

Graphene oxide-based large-area dynamic covalent interfaces

“…In summary, GO-based LDCIs are realized via the spatially connected and consecutive occurrence of DCB-based local reversible covalent reactions, allowing long-range migration of chemical compositions along the interface. The effective strategies to realize GO-based LDCIs, including water adsorption, 74 interfacial curvature 75 and metal–substrate support, 76 together with the potential applications of LDCIs in water dissociation 77 and humidity sensing 78 are summarized. Additionally, we also give an outlook on potential strategies to implement LDCIs on other 2D carbon-based materials, including the interfacial morphology 79 and periodic element doping.…”

“…The first application is LDCI-assisted water dissociation. 77 Fig. 4(a) depicts the water adsorption configurations on GO and GO@copper, each with a pair of hydroxyl and epoxy groups.…”

“…The effective strategies to realize the GO-based LDCIs, such as water adsorption, 74 interfacial curvature 75 and metal–substrate support, 76 are presented. Moreover, the applications in water dissociation 77 and humidity sensing, 78 and an outlook on potential strategies on other 2D carbon-based materials with different interfacial morphologies 79 or element doping 80 is also discussed. This work provides insights into the realization LDCIs on a wider range of 2D materials, including borophene, 81 MoS 2 82 and MXene, 83 and offers a theoretical perspective for advancing materials with long-range dynamic characteristics and improved performance, including controlled drug delivery/release and high-efficiency (bio)sensing.…”
