Chain-ordered Pt atoms with delocalized electronic structure for improved hydrogen production.

ABSTRACT: As the smallest one-dimensional structure, single-atom chains exhibit many one-dimensional quantized behaviors, such as Tomonaga-Luttinger liquid behavior, high-temperature superconductivity, and fluctuations. In contrast to single-atom catalysts, there is growing interest in exploring whether and how the point-to-point interaction occurs between neighboring metal atoms in 1D chains. Here, we controllably fabricate Pt chains and single atoms in MoS₂ films with similar coordination environments and conduct model studies on their catalytic behaviors in hydrogen production. Combining calculations with field effect transistor and micro-electrochemical measurements, we reveal that the chains exhibit significant delocalized electron densities, which underpins their metallic behavior a
