Direct liquid fuel cells (DLFCs) are considered as satisfactory alternatives to traditional fossil fuels owing to their unique advantages, e.g. environmental friendliness and easy storage. Noble metal catalysts are widely used to improve the efficiency of DLFCs. However, the high cost, low utilization and poor stability of noble metals restricted their practical applications. Therefore, it is of great significance to explore cost-effective electrocatalysts and further improve their electrocatalytic performance. Reducing the content of noble metals by adding low-priced phosphorus (P) has been considered as an effective strategy, which is able to enhance their electrocatalytic activity and anti-poisoning ability through effectively changing the electronic density of active sites. In the past few years, tremendous P containing catalysts have been synthesized and utilized in DLFCs. In this review, we summarize the fundamentals of electrochemical reactions and present recent progress in P containing noble metal catalysts for DLFCs, including the discussion of their shape, composition and the relationship between P and active sites. Finally, the challenges and some potential directions in this field are pointed out.

用于直接液体燃料电池的含磷贵金属电催化剂的最新进展
直接液体燃料电池 (DLFC) 由于其独特的优势，被认为是传统化石燃料的令人满意的替代品，例如环保且易于储存。贵金属催化剂被广泛用于提高 DLFC 的效率。然而，贵金属成本高、利用率低、稳定性差等问题限制了其实际应用。因此，探索具有成本效益的电催化剂并进一步提高其电催化性能具有重要意义。通过添加低价磷（P）来降低贵金属的含量被认为是一种有效的策略，它可以通过有效改变活性位点的电子密度来提高其电催化活性和抗中毒能力。在过去的几年中，大量的含磷催化剂被合成并用于 DLFC。在这次审查中，我们总结了电化学反应的基本原理，并介绍了用于 DLFC 的含 P 贵金属催化剂的最新进展，包括讨论它们的形状、组成以及 P 与活性位点之间的关系。最后指出了该领域的挑战和一些潜在的方向。
