Applications of Nanomaterials for Water Quality Sustainability: Present Status and Future Trends

Abstract

The diversity of water pollution and the depletion of some water resources have continued to linger despite several governmental and non-governmental programmes, especially in developing countries for water quality sustainability. This problem has reduced potable water availability, and it has increased water-related diseases in these countries. These problems are severe, mostly, in drought prone areas where water supplies and treatments are still at an infant stage. Hence, researchers are proposing the application of nanomaterials for water treatment and desalination. However, nanomaterials can also turn to be water pollutants that can threaten the public health if handled carelessly. This study, therefore, presents the applications and implications of nanomaterials in relation to water treatment and water quality. The review results highlighted the state-of-the-art and prospects of nanomaterials for water desalination and water quality production.

An Overview of the Emerging Technologies and Composite Materials for Supercapacitors in Energy Storage Applications

“…Supercapacitors offer higher energy than ordinary capacitors of comparable size, because their electrode materials have large surface areas [ 31 , 32 , 33 , 34 ]. There are many names for supercapacitors, including ultracapacitors and electric double-layer capacitors [ 35 , 36 , 37 ]. Supercapacitors are preferable to batteries because of their higher power density, but their lower energy density remains a challenge [ 38 , 39 ].…”
