Developing a high-performance photocatalyst and a photoelectrode with enhanced visible light harvesting properties is 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-metals. The novel milled RP showed significantly enhanced photocatalytic and photoelectrochemical performances with a lower charge transfer resistance compared to commercial RP under wide visible photoirradiation, making it a feasible alternative for photocatalytic applications.
开发具有增强的可见光捕获性能的高性能光催化剂和光电极对于实际的可见光光催化应用至关重要。通过简便的机械球磨法制备了无贵金属、高可见光活性的元素红磷(RP),这是一种可重复、低成本且可控的合成过程。该合成使用了廉价且丰富的原材料,因为大多数RP杂化物基于昂贵的贵金属。与商业RP相比,新型球磨RP在宽可见光照射下表现出显著增强的光催化和光电化学性能,且电荷转移电阻更低,使其成为光催化应用的可行替代物。
