Super-Nano Turing Catalysts Integrated Into High-Performance Anion Exchange Membrane Water Electrolyzer For Large-Scale And Low-Cost Hydrogen Production

Energy sustainabiliN, mitigation of global warming and environment-friendly technological revolution related to clean energy utilization have been the top global focus. A promising technology is to transform renewable energy into hydrogen fuel which has the largestgravimetric energy density of 142 MJ/kg among all the chemical fuels. However, the largescale application of clean water-splitting electrolysis for high-purity H2 production is limited by the low efficiency and high cost (US$4.15 - 23.27 per kg) because of the highoperating voltage. This study aims to develop super-nanostructured Turing catalyst with high catalytic activity and excellent long-term durability, which will be applied in highperformance anion exchange membrane water electrolysis for high-purity H2 generation.The advanced physical vapor deposition technology will be employed to prepare the Turing catalysts at the engineering scale with the advantages of low cost and large mass production. This project will set up a new paradigm for material design of low-dimensionalcatalysts, and the advantages of these super-nano Turing-structured materials with corresponding preparation technologies could overcome the technical and cost barriers for large-scale engineering applications of anion exchange membrane water electrolysis
