本文采用真空封装原位磷化法，结合脉冲激光沉积技术，制备了集成在石墨纸上的多孔纳米片阵列（P-WP 2 NS/GP），作为电催化析氢反应（HER）的三维柔性阴极。与未经预沉积处理的电极相比，提高的催化活性归因于增加的有效催化剂负载量和增强的电荷传输动力学。这些结果使目前的P-WP 2 NS/GP成为一种有前途的能量转换阴极，并为设计和制造高效电极铺平了新的道路。（C）2017 Elsevier B. V.版权所有。
Herein, porous WP2 nanosheet arrays integrated on graphite paper (P-WP2 NSs/GP) as 3D flexible cathode for electrocatalytic hydrogen evolution reaction (HER) are prepared by in situ phosphidation via vacuum encapsulation assisted by pulsed laser deposition technique. Compared to the electrode without pre-deposition process, the enhanced catalytic activities are attributed to the increased effective catalyst loading and the reinforced charge transport kinetics. The results make the present P-WP2 NSs/GP as a promising cathode for energy conversion and paves a new way for designing and fabricating efficient electrodes toward HER. (C) 2017 Elsevier B.V.
