摘要
地球富集的高效电催化剂因实现析氧反应（OER）的彻底突破和探索可持续能源而受到广泛关注。本研究采用易烧合成的方法，在木棉纤维（KF）上生长了具有三维空心管结构的CoP3/MoO3复合材料。由于CoP3和MoO3异质界面的构建有利于电子的快速转移，合成的CoP3/MoO3/KF@ME在碱性电解质中表现出优异的电催化OER性能，在10 mA cm−2和50 mA cm−2下的过电位分别为208 mV和351 mV， Tafel斜率较小，分别为73 mV dec−1。这项工作有助于构建非贵金属和生物质衍生的纳米材料。图形抽象
Facile Synthesis of CoP3/MoO3 Nanoparticles Grown on Kapok Fiber for Efficient Oxygen Evolution Reaction
Earth-abundant and efficient electrocatalysts have attracted widespread attention for achieving thorough breakthrough of the oxygen evolution reaction (OER) as well as exploring sustainable energy. In this research, a CoP3/MoO3 composite grown on the kapok fiber (KF) with 3D hollow tubular structure was obtained using a facile calcining synthesis approach. Due to the construction of CoP3 and MoO3 heterointerface favoring the fast electron transfer, the as-synthesized CoP3/MoO3/KF@ME showed excellent electrocatalytic OER performance, showing low overpotentials of 208 mV at 10 mA cm−2 and 351 mV at 50 mA cm−2 with a small Tafel slope of 73 mV dec−1 in alkaline electrolyte, respectively. This work helped to construct a non-precious metal and biomass-derived nanomaterial.
