Design and Development of a Solar Water Purification System with Graphene-Plasmonic Based Hybrid Nanocomposites: A Review

Abstract

Harvesting solar energy for water treatments has been considered a promising solution for a global community. The shortage of water is a great challenge for scientists due to the increased demand of the population-however, the low efficiency of absorber materials obstacles in practical applications. In addition, state-of-the-art conventional technologies require optical concentrators and multiple component-based systems, leading to lower efficiency and higher cost. In this review, a low-cost, more reliable, less energy-intensive, and more eco-friendly solar water purification system based on graphene-plasmonic hybrid nanocomposite has been demonstrated. Graphene-plasmonic-based hybrid nanocomposite has been utilized to achieve pure water from wastewater. Such hybrid nanocomposites have the ability to clean polluted water very efficiently due to their excellent properties such as higher surface area, low concentration, and working ability. Furthermore, the development of a solar water purification system has been achieved through optimized hybrid nanocomposites.
