## Description

- description: Heteroassembly of chemically exfoliated nanosheets (NSs) has been explored
    to produce functional two-dimensional materials for a wide range of applications
    in electronic and energy devices. In this study, the molecular-scale assembly
    approach is extended to construct visible-light active and stable photoelectrodes
    consisting of narrow- and wide-bandgap semiconductor units, i.e., MoS2 and Ti0.87O2
    NSs, which contribute with complementary roles to the performance of the photoelectrodes.
    As a visible–light response element, 2H phase MoS2 NSs possessing high crystallinity
    were electrochemically exfoliated from a MoS2 crystal and functionalized via interface
    modification, yielding an absorbed photon-to-electron conversion efficiency that
    was two orders of magnitude higher than that of previously studied defective MoS2
    NSs synthesized via Li intercalation. Furthermore, the controlled interfacial
    coupling between corrodible MoS2 NSs and a chemically stable, visible-light transparent
    Ti0.87O2 NS coating resulted in the enhanced photoelectrode durability due to
    the hole tunneling ability inherent to ultra-thin insulating oxide layers. Therefore,
    the visible-light responsivity of MoS2 and the chemical stability of Ti0.87O2
    NSs were complementary combined in the interface-engineered heteroassembly system.
    This photoelectrode design can be expected to be applicable to other combinations
    of visible–light active narrow-bandgap and corrosion–protective wide-bandgap NS
    units compatible with various reaction systems.
