Abstract:
Single‐atom catalysts are heterogeneous catalysts with atomistically dispersed atoms acting as a catalytically active center, and have recently attracted much attention owing to the minimal use of noble metals. However, a scalable and inexpensive support that can stably anchor isolated atoms remains a challenge due to high surface energy. Here, copper‐halide polymer nanowires with sub‐nanometer pores are proposed as a versatile support for single‐atom catalysts. The synthesis of the nanowires is straightforward and completed in a few minutes. Well‐defined sub‐nanometer pores and a large free volume of the nanowires are advantageous over any other support material. The nanowires can anchor various atomistically dispersed metal atoms into the sub‐nanometer pores up to ≈3 at% via a simple solution process, and this value is at least twice as big as previously reported data. The hydrogen evolution reaction activity of −18.0 A mg Pt −1 at −0.2 V overpotential shows its potential for single‐atom catalysts support.
