Developing high-performance photoctalysts and photoelectrode with enhanced visible light harvesting properties are essential for practical visible light photocatalytic applications. Noble metal-free, highly visible light-active, elemental red phosphorus (RP) was prepared by a facile mechanical ball milling method, which is a reproducible, low cost and controllable synthesis process. The synthesis used inexpensive and abundant raw materials because most RP hybrids are based on expensive noble-metal. The novel milled RP showed significantly enhanced photocatalytic and photoelectrochemical performance with a lower charge transfer resistance than commercial RP under wide visible photoirradiation, making it a feasible alternative for photocatalytic applications.1
