Engineering ultrafine PtIr alloy nanoparticles into porous nanobowls via a reactive template-engaged assembly strategy for high-performance electrocatalytic hydrogen production

We demonstrate self-sacrificial templated strategy for the synthesis of hollow and porous PtIr alloyed nanobowls composed of ultrafine nanoparticles and the resulting self-supported Pt 7 Ir NBs exhibit superior HER performance.
