Sulfur copolymer nanowires have been reported for the first time as highly stable visible-light-active photocatalysts for photoelectrochemical water splitting depending on their size and sulfur content. The as-prepared sulfur copolymer nanowires can serve as a sulfur source and templates to create metal sulfide/copolymer heterocatalysts.
