Abstract: In the pursuit of sustainable development, the world faces two key challenges: effective waste management and improved energy efficiency. In this context, it is necessary to propose a chlorine-centered sustainable solution, as the related industries consume large amounts of electricity and precious metals while generating significant quantities of plastic waste. Here, we report a chloride electrocatalyst of titanium nitride-supported ruthenium single-atoms (Ru1@TiN) that exhibits high efficiency for chlorine evolution reaction of NaCl in multi-conditions, with a nearly 100% selectivity in a wide range of pH values, potentially saving some of the electricity for the chlor-alkali industry. Moreover, Ru1@TiN can decompose polyvinyl chloride waste into chlorine and other valuable chemicals, providing an approach to plastic upcycling and green chlorine production. A coordination-derived activation mechanism on TiN support is uncovered and a dynamic polyatomic active site is proposed to explain the achieved catalytic performances. This work will benefit developing sustainable chlorine chemical industries. The development of robust catalysts that could work under industrial-scale current densities remains a challenge for chlor-related reactions. Here, the authors report an activation method for designing efficient ruthenium single-atom catalysts that enhance chlor-related production and recycling.
