Recent developments in conductive polymers based electro/photoelectrocatalytic materials for effective hydrogen/oxygen evolution reactions: A review

Von Wiley-VCH zur Verfügung gestellt

Currently, substantial greener energy source such as hydrogen fuel cell as an alternative for fossil fuel source, and much of research has been dedicated to achieving highly efficient hydrogen (H2 gas) generation. In this line, electrochemical water splitting that involves hydrogen and oxygen evolution reactions (HER and OER, respectively) is considered to be the most greener and effective hydrogen-generating procedures with only water as by-product. However, the process of successful OER/HER, it is extremely demand for electrocatalyst with high activity, stability and cost effective for water splitting process. Herein, the review proposed a promising electrocatalysts such ass conductive polymers (CPs) with enhanced catalytic effect with the polymer encapsulation of catalytic material provides increase in charge transfer kinetics both in OER/HER. Also, the review highlights OER and HER mechanism of conducting polymers and their effect with the synergism was discussed detail. Also, the review detailed the reduced overpotentials, importance and enhancement of catalytic efficiency with various polymers reported in both OER and HER. Here, the choice of polymers can matrix with the inorganic active sites to prevent them from aggregation and the water splitting carried out over the electrode surface results good conductivity to charge transfer from the electrode to the active sites. In addition, the review discussed about the polymers induces the photon effect with the photoelectrocatalytic water splitting. Thus, the combing effect with conducting polymers and the materials with catalytic active centers open up a new kind of electrocatalyst for synthesis.
