Abstract

Designing advanced electrocatalysts with high methanol tolerance in the oxygen reduction reaction process is crucial for the sustainable implementation of direct methanol fuel cells. Herein, we present a Pt/C catalyst modified with black phosphorus (BP) nanodots (BPNDs-Pt/C) by using a facile ultrasonic mixing method. Experimental and computational investigations reveal that the electron transfer from BP to Pt leads to weak adsorption of hydroxyl groups on the Pt surface. As a result, the BPNDs-Pt/C catalyst exhibits efficient activity and anti-methanol ability for cathodic oxygen reduction electrocatalysis in an acidic medium. Additionally, it demonstrates high activity for oxygen reduction reaction (ORR) in an alternative alkaline system with cation exchange membrane and eliminable methanol penetration. This work highlights the feasibility of using non-metallic elements to regulate the electronic structure and surface properties of Pt-based nanomaterials. Furthermore, the designed BPNDs-Pt/C electrocatalyst, with controllable ORR performance, can be applied across various scenarios based on demand.

用于直接甲醇燃料电池中甲醇耐受性氧还原的黑磷纳米点修饰 Pt/C 电催化剂

在氧还原反应过程中设计具有高甲醇耐受性的先进电催化剂对于直接甲醇燃料电池的可持续实施至关重要。在此，我们采用简便的超声波混合方法，制备了一种用黑磷（BP）纳米点（BPNDs-Pt/C）修饰的 Pt/C 催化剂。实验和计算研究表明，从 BP 到 Pt 的电子转移会导致羟基在 Pt 表面的弱吸附。因此，BPNDs-Pt/C 催化剂在酸性介质中进行阴极氧还原电催化时表现出高效的活性和抗甲醇能力。此外，该催化剂在带有阳离子交换膜和可消除甲醇渗透的替代碱性体系中的氧还原反应（ORR）中也表现出很高的活性。这项工作凸显了利用非金属元素调节铂基纳米材料的电子结构和表面特性的可行性。此外，所设计的 BPNDs-Pt/C 电催化剂具有可控的 ORR 性能，可根据需求应用于各种场景。
