Low-cost flexible textile electrocatalyst for overall water splitting

Through the braidability of cotton fiber and the richness of surface functional groups, cotton fiber can be woven into any shape, and catalytically active centers can be stably anchored on the fibers. During the electrocatalytic overall water splitting (OWS) process, catalyst shedding and activity reduction can be effectively avoided. Owing to the braidability and the richness of surface functional groups, cotton fibers can be woven into different shapes and sizes, and diverse catalytically active centers can be stably anchored.
