光催化剂已经被广泛研究了几十年，在能源生产、环境治理和化学合成方面具有巨大的应用潜力。新型光催化剂和调控光催化剂性能的新方法的发现推动了光催化技术的发展。自从Ag3PO4光催化剂被发现以来，由于具有∼2.4eV禁带、相对较高的光吸收和较强的氧化能力以及显著的高量子效率的半导体的独特性质而引起了研究人员的关注。然而，由于体相Ag3PO4中的光致还原反应和不协调的带隙，导致其光稳定性较低，限制了其应用。设计具有最佳带隙、表面性质和稳定性的Ag3PO4基光催化剂具有重要意义。本文在了解Ag3PO4的结构和内部机理的基础上，从微观结构控制、常规材料(半导体、金属和碳材料)和新型材料(新型无机材料、MOF、天然材料和聚合物)的复合以及掺杂等方面对Ag3PO4的性能调控方法进行了综述。此外，我们还介绍了近年来提出的包括导体复合材料、异质结、Z-型和S-型异质结在内的多种复合机制。通过归纳这些管制方法中常用的模型，系统地讨论了这些管制方法的优缺点。此外，对解决环境带来的影响也注意到了更深层次的研究。重点介绍了Ag3PO4基光催化剂在能源生产、环境净化、甚至生物医药等领域的应用。我们总结了对该领域未来挑战的展望。相信以我们的观点和结论，可以加速对Ag3PO4的研究和应用。
Photocatalysts had been extensively investigated for decades and had great potential to apply in energy production, environmental treatment, and chemical synthesis. The discovery of new types photocatalysts and new methods to regulate and control the performance of photocatalysts has driven the development of photocatalysis. Since the discovery of Ag3PO4photocatalyst, it has attracted the researchers’ attention arising from the unique properties of semiconductor with ∼2.4 eV band-gap, relatively high light-absorption and the strong oxidative ability, together with prominently high quantum efficiency, as compared with the other counterparts. However, the low photostability originating from photoinduced reductive reaction in the bulk Ag3PO4and discordant bandgap restrains its application. The design of Ag3PO4-based photocatalysts with optimized bandgap and surface properties as well as stability is of great importance. In this paper, with the comprehension of the structure and internal mechanism in hand, many ways to regulate the performance of Ag3PO4in term of microstructure controlling, conventional materials (semiconductors, metals, and carbon materials) and novel materials (novel inorganic materials, MOFs, natural materials, and polymers) compositing, together with doping were reviewed. Moreover, we introduced multiple mechanisms of the composites that were put forward in recent years consisting of conductor composite, heterojunction, and Z-scheme and S-scheme heterojunctions. By concluding the prfoposed models among these regulation methods, we systematically discussed the advantages and disadvantages among these regulation methods. Besides, the deeper researches on the effects brought by the solution environment also were noticed. We focused on the applicability of Ag3PO4-based photocatalysts in many fields such as energy production, environmental purification, even in biological medicine. We conclude the perspective toward the future challenges in the field. It's believed that the researches and applications on Ag3PO4may be accelerated with our perspective and conclusion.
