Herein, nanoneedle-constructed WO3 flowers are prepared by hydrothermal synthesis, which are characterized by a large surface area leading to abundant active sites. Additionally, P doping is employed as an effective way to generate charge imbalance and induce more empty d-orbitals around W6+, thus facilitating the adsorption of N2 molecules. Moreover, a flexible TiO2 nanofibrous membrane is used as an electrocatalytically active matrix to fix the P-doped, nanoneedle-constructed WO3 flowers. The hierarchically structured P-WO3@TiO2 nanofibrous membrane acts as a self-supported electrocatalyst, presenting an enhanced ammonia yield (6.54 × 10−10 mol s−1 cm−2) and faradaic efficiency (17.5%) compared to the undoped counterpart.

固定在TiO2纳米纤维膜上的P掺杂WO3花，用于增强N2的电还原
在本文中，通过水热合成制备了纳米针构造的WO 3花，其特征在于表面积大导致活性位点丰富。此外，P掺杂被用作产生电荷不平衡并诱导W 6+周围更多空d轨道的有效途径，从而促进了N 2分子的吸附。此外，柔性的TiO 2纳米纤维膜被用作电催化活性基质，以固定P掺杂，纳米针构造的WO 3花。分层结构的P-WO 3 @TiO 2纳米纤维膜起自支撑电催化剂的作用，氨产率提高（6.54×10 -10mol s -1 cm -2）和法拉第效率（17.5％）相比，未掺杂的对应物。
