Nanomaterials for Enhanced Desalination Efficiency using Solar Energy

Nanomaterials for Enhanced Desalination Efficiency using Solar Energy

High thermal conductivity and hydrophobic characteristics of graphite and carbon nanotube nanoparticles are well-known, and they can reduce energy loss and promote effective heat transfer throughout the distillation process. Such solar cells can be developed thanks to nanotechnology. Further feasible uses will arise from the production of thin and flexible solar cells using nanomaterials like graphene or carbon nanotubes. According to earlier research, a solar still's (SS) surface and evaporation rate play a major role in its efficiency. The evaporation rate can be increased by using different wick materials. When compared to traditional fluids, nanofluids have the following benefits, which makes them appropriate for usage in solar collectors: By altering the nanoparticles' size, shape, composition, and volume fraction, solar energy absorption will be optimised. At the moment, stainless steel is the material that desalination plants utilise the most frequently. Titanium is the best material to utilise in desalination plants since it corrodes very little or not at all in saltwater conditions. The two main categories of desalination methods utilised globally can be generically categorised as membrane or thermal.

 Energy is required for both methods to function and generate fresh water. There are subcategories (processes) using various methodologies within those two major groups. Since desalinated water is gradually acidic and corrosive to water pipes, the desalination facilities add calcium before distributing the water to the national water carriers. Adding calcium is not too expensive and aids in the fight against acidity. Water can be distilled using solar energy that has been captured in thermal or electrical form. Solar energy is absorbed by solar thermal energy systems, which include evacuated tubes, solar ponds, flat plate solar collectors, and concentrating solar troughs. The thermal energy produced by these systems powers thermal desalination operations. The most popular method uses less energy than the others because it relies on the use of semipermeable membranes that let water in but keep salt out. Since the ultra-thin polyamide used to make these membranes is prone to bacterial contamination, the water needs to be cleaned. Enhancing solar cell efficiency is largely dependent on nanotechnology. Increased surface area in solar cells enables more effective light absorption with the incorporation of nanomaterials like nanostructured silicon or titanium dioxide. Metals, oxides, carbides, or carbon nanotubes are the most common materials for nanoparticles utilised in nanofluids. Oil, ethylene glycol, and water are typical base fluids.

Intentionally created nanomaterials fall into four categories: metal-based, carbon-based, dendrimer-based, and nanocomposites. Fullerenes are purposefully manufactured nanomaterials based on carbon. Graphene, fullerene, single-walled and multiwalled carbon nanotubes, carbon fibre, activated carbon, and carbon black are examples of carbon-based nanomaterials. Because of their special optical, thermal, and electrical characteristics, silver nanoparticles are prized. These characteristics make them a fascinating addition to research and development for a variety of goods and technologies, such as chemical sensors, biological applications, and photovoltaics. Highly adjustable porous structures called metal-organic frameworks (MOFs) are being investigated for their potential to produce desalination membranes that use less energy. In addition, scientists are looking into the potential of nanoparticles like silver and zeolites to eliminate impurities in addition to salt.
