Summary: The precise construction of highly efficient triple-atom catalysts (TACs) remains a significant challenge. Here, we present a protocol for constructing asymmetric Pt-Ru-Co triple-atoms (TAs) supported on nitrogen-doped carbon nanotubes (NCNTs) via selective atomic layer deposition (ALD) technology. We describe steps for synthesizing the NCNT substrate, deposition of Pt-Ru-Co TAs, and characterizing the materials. We then detail procedures for preparing the electrolyte solution and working electrode followed by electrochemistry measurements for hydrogen evolution and hydrogen oxidative reactions with a typical three-electrode system.For complete details on the use and execution of this protocol, please refer to Zhang et al.1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
