Herein, we report the synthesis of a new supramolecular polymeric network (PCN) assembled through crosslinking of propyl bromide substituted tetraphenyl porphyrin with perhydroxy-cucurbit [8]uril and its use in the electrocatalytic hydrogen evaluation reaction after loading with nickel and integrating with in situ-electrochemically reduced graphene oxide (ERGO). Electrode was prepared by first coating graphene oxide on the FTO substrate followed by layering the nickel loaded PCN and finally by applying an appropriate voltage to reduce the graphene oxide in situ electrochemical reaction. The loading of nickel cocatalyst into PCN together with the integration of ERGO layer substantially improved its HER efficiency. Effect of various concentrations of Ni and GO on the HER activity of the developed electrocatalyst were investigated. Therein, ERGO₁/Ni₂@PCN catalyst containing 41% Ni and 50% GO (with respect to PCN) with only one layer of each component demonstrated excellent HER activity and stability with low onset and overpotentials of −20 mV, η@10 mA cm⁻² of −360 mV, respectively, and remarkable hydrogen generation rate of 27.5 mmol h⁻¹ g⁻¹ in 1 M KOH. This noble-metal-free catalytic system is simple yet highly promising for the efficient hydrogen evolution reaction from water splitting.

在此，我们报道了通过溴代四苯基卟啉与过羟基葫芦 [8] 脲的交联合成的新型超分子聚合物网络 ( PCN ) 及其在负载镍和原位整合后在电催化氢评价反应中的应用。 -电化学还原氧化石墨烯（ERGO）。通过首先在 FTO 基底上涂覆氧化石墨烯，然后将负载镍的PCN分层，最后通过施加适当的电压来还原氧化石墨烯的原位电化学反应来制备电极。将镍助催化剂加载到PCN 中并结合ERGO层大大提高了其 HER 效率。研究了不同浓度的 Ni 和GO对所开发的电催化剂的 HER 活性的影响。其中，含有 41% Ni 和 50% GO（相对于PCN）且每种组分仅一层的ERGO ₁ /Ni ₂ @PCN催化剂表现出优异的 HER 活性和稳定性，具有 -20 mV、η@10 的低起始和过电位mA cm ^-2分别为 -360 mV 和 27.5 mmol h ^-1  g ^{-1 的}显着氢气生成率在 1 M KOH。这种不含贵金属的催化体系很简单，但对于水分解的高效析氢反应非常有希望。
