## Description

- description: Development of efficient electrocatalysts for hydrogen evolution reactions
    (HERs) is necessary to achieve environmentally friendly and sustainable hydrogen
    production. To reduce cost and to circumvent the scarcity of platinum, the most
    efficient catalyst for HER, it is essential to develop catalysts using ubiquitous
    base metals or minimal amounts of precious noble metals. Bis(diimino)metal (MDI)
    coordination nanosheets are potential HER catalysts because their electric conductivities,
    two-dimensionality, and porous structures provide large surface areas and efficient
    mass and electron transfer. In addition, with sparse metal arrangements in their
    chemical structures, nanosheets can reduce the amount of metal needed. We synthesized
    bis(diimino)palladium coordination nanosheets (PdDI) as a coordination polymer
    composed of bis(diimino)palladium, with semiconducting characteristics, using
    gas-liquid interfacial synthesis and electrochemical oxidation. These electrochemically
    synthesized PdDIs exhibit remarkable catalytic performance with overpotential
    reaching 10 mA cm−2 of 34 mV, a Tafel slope of 47 mV dec−1, and an exchange current
    density of 2.1 mA cm−2 after appropriate activation. This performance is closely
    comparable to that of metallic platinum. An ex-situ investigation of the activation
    process revealed that reduction of the divalent Pd center in bis(diimino)palladium
    produced a composite of Pd(0) species and PdDI, combining high catalytic activity
    with smooth electron transfer.
