Synergistic interaction and hybrid association of conducting polymer photocatalysts/photoelectrodes for emerging visible light active photocatalytic applications

The fascinating properties of conducting polymers have led to a thorough exploration of the hybrid association between conducting polymers and semiconductors, specifically in relation to their synergistic interaction and association for developing high-performance photocatalytic materials. The overall activity of a conducting polymer is greatly influenced by its design and fabrication, alongside its optical and electronic properties that determine its performance. This review provides a comprehensive understanding of various types of conducting polymers along with the correlation between their dimensional structure and optical and electronic behaviours. Furthermore, the impact of synthesis techniques on the development of photocatalysts and photoelectrodes is also discussed. In this paper, we explore the intriguing realm of conducting polymers and explore their significance in a variety of photocatalytic reactions. These polymers have given rise to extraordinary advancements in cutting-edge technologies. Yet, boosting their photocatalytic efficacy at the smallest scale is a challenge that needs to be resolved, probably due to the fact that this opens the door to environmentally and energy-friendly applications for a sustainable future. The bottom line is that our study also uncovers a gap in the current application of these polymers. It is an appeal for a closer look, promoting an in-depth study of their potential impact on various photocatalytic applications. This review emphasises the synergistic interaction in conducting polymer hybrids for boosted visible-light photocatalysis, focusing on enhancing optoelectronic properties.
