Abstract

Herein, we report a magnetic field-guided hydrothermal method for the controlled synthesis of 1T-phase molybdenum disulfide (MoS₂) under 0.4 T magnetic induction. This novel synthesis strategy significantly enhances both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) catalytic activities when compared to conventional preparation methods conducted without magnetic field intervention. The fabricated 1T-phase MoS₂ exhibited low overpotentials of 99 mV for HER and 320 mV for OER at 10 mA cm⁻², along with small Tafel slope values of 84 and 71 mV dec⁻¹, respectively, indicating faster reaction kinetics. This study establishes a magnetic-field assisted synthetic paradigm for designing high-performance bifunctional HER/OER catalysts.

协同磁场感应和钴离子掺杂：高效合成用于HER/OER电催化的1T相二硫化钼

本文报道了在0.4 T磁感应强度下，磁场引导水热合成1t相二硫化钼（MoS2）的方法。与没有磁场干预的传统制备方法相比，这种新的合成策略显著提高了析氢反应（HER）和析氧反应（OER）的催化活性。制备的1t相MoS2在10 mA cm−2下，HER过电位为99 mV， OER过电位为320 mV， Tafel斜率分别为84 mV和71 mV dec−1，表明反应动力学更快。本研究为设计高性能双功能HER/OER催化剂建立了磁场辅助合成范例。
