The design of active and stable electrocatalysts for the methanol oxidation reaction (MOR) plays a vital role in the large-scale commercialization of direct methanol fuel cells. Herein, one-dimensional P-doped PtTe nanotubes with uniform mesoporous shells (P-PtTe MNTs) have been synthesized using F127 and Te nanowires as the dual template and trioctylphosphine as the phosphorus dopant. The resultant P-PtTe MNTs with sufficient exposed surface atoms can improve the atom utilization of Pt. Moreover, the incorporation of P atoms into Pt lattices can tailor the electronic structure of Pt and induce a strong synergic effect, thus leading to highly active and durable performance for the MOR. This phosphorus doping is very valuable for controllable synthesis of various metal–nonmetal catalysts with desired morphologies.

掺P的PtTe介孔纳米管电催化剂

用于甲醇氧化反应（MOR）的活性和稳定电催化剂的设计在直接甲醇燃料电池的大规模商业化中起着至关重要的作用。本文中，已经使用F127和Te纳米线作为双模板并以三辛基膦作为磷掺杂剂合成了具有均匀介孔壳的一维P掺杂PtTe纳米管（P-PtTe MNT）。具有足够暴露的表面原子的所得P-PtTe MNT可以提高Pt的原子利用率。此外，将P原子结合到Pt晶格中可以定制Pt的电子结构，并产生强大的协同效应，从而导致MOR具有高活性和持久性。这种磷掺杂对于可控制地合成具有所需形态的各种金属-非金属催化剂非常有价值。
