Abstract

The development of electrochemical water splitting catalysts have low cost and long-life high-performance generation of H₂ and O₂. We present the study about the polymeric electrolytes as PU.PANI.FeS2 composed of Polyurethane (PU), Polyaniline (PANI) and iron sulfide (FeS2) used in electrochemical water splitting and H₂ and O₂ production and now, s study enhances the efficiency of H2 production efficiency. This study may begin a new opening for 𝜋- conjugated polymers, metal-free porphyrin-based crystalline covalent organic polymer, triphenylphosphine skeleton (HCP-PPh3) for sustainable hydrogen and oxygen production. The polypyrene (PPy) conducting polymer enhance photocatalytic activity. Coordination polymers (CPs) have a considerable contribution for use of polymers in noble-metal-free water splitting by electrochemical method by the hydrogen/oxygen evolution reactions (OER/HER). The bimetallic coordination polymers improve the conductivity, and the composites material shows excellent performance with a small Tafel slope and high faradaic efficiency. Whole water splitting produces a current density of 10mA cm-2 at a voltage 1.52V with excellent durability. The polymer of tandem solar cells is also used for electrochemical water splitting which have high power conversion efficiency. The micro patterned Polyurethane Acrylate (PUA) are also efficient in photo electrochemical water splitting. The Polymer Electrolyte Water Electrolysis (PEWE) cell used for high pressure operation. The physical (X-Ray diffraction XRD, Scanning Electron Microscopy (SEM), Energy-Dispersive X-ray Spectroscopy (EDX)) and electrochemical (Cyclic Voltammetry (CV), Linear Sweep Voltammetry (LSV), Fourier transform infrared spectroscopy (FT-IR Electrochemical Impedance Spectroscopy (EIS) methods are used for characterization. The results can help us to future enhance efficiency targets and points towards next generation PEWE materials.
