A flexible Platinum Nanoleaves (PtNLs) deposited molybdenum disulfide/reduced graphene oxide composite paper was successfully prepared for catalyzing the hydrogen evolution reaction (HER). Synthesis of composite paper was achieved through vacuum filtration of homogeneous dispersions, consisting of molybdenum disulfide (MoS₂) and graphene oxide (GO). After chemical reduction of MoS₂/GO paper with HI, it transformed to MoS₂/reduced graphene oxide (rGO) paper and used as the working electrode in a three‐electrode cell to deposit PtNLs by electroreduction method. The as‐prepared PtNLs‐MoS₂/rGO paper was characterized by X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and Raman spectroscopy. When PtNLs‐MoS₂/rGO paper rolled up, it can be used directly as a catalyst with the enhanced surface area in a small space and exhibit high‐performance HER activity with a small onset overpotential of 62 mV and a low Tafel slope of 60 mV/dec as well as excellent electrocatalytic stability. The present work provides a potential way to design catalyst for HER through controlling the shape.

柔软，独立式的PtNLs-MoS2 /还原氧化石墨烯复合纸：用于析氢反应的高性能卷纸催化剂

成功制备了柔性的铂纳米叶（PtNLs）沉积二硫化钼/还原氧化石墨烯复合纸，用于催化析氢反应（HER）。通过真空过滤由二硫化钼（MoS ₂）和氧化石墨烯（GO）组成的均匀分散体，可以实现复合纸的合成。用HI对MoS ₂ / GO纸进行化学还原后，将其转化为MoS ₂ /还原氧化石墨烯（rGO）纸，并用作三电极电池中的工作电极，以通过电还原法沉积PtNLs。准备好的PtNLs-MoS ₂/ rGO纸的特征在于X射线衍射（XRD），X射线光电子能谱（XPS），扫描电子显微镜（SEM）和拉曼光谱。当PtNLs-MoS ₂ / rGO纸卷起时，可以直接用作催化剂，在较小的空间内增加表面积，并具有高性能的HER活性，起始电位低至62 mV，Tafel斜率低至60 mV / dec以及出色的电催化稳定性。本工作提供了通过控制形状来设计用于HER的催化剂的潜在方法。
