A review on the role of nanomaterials in the removal of organic pollutants from wastewater

Loading and Release of Charged and Neutral Fluorescent Dyes into and from Mesoporous Materials: A Key Role for Sensing Applications

“…However, in the last years the scope of this technology has been expanded toward applications in a variety of sectors such as agriculture [3,4], photovoltaic cells [5] external coatings [6] or personal care and cosmetics [7], employing as nanoparticles drug carriers (NPs) of organic [8][9][10] or inorganic [11] nature. Among these materials, microporous and mesoporous materials, due to their chemical inertness, homogeneous porosity and large internal surface area, have attracted considerable research interest for applications on the fields of drug delivery [12][13][14], catalysis [15][16][17], filtration and separation [18,19], gas adsorption [20,21] and storage [22,23], enzyme immobilisation [24,25], biomedical tissue regeneration [26,27], environmental remediation [28][29][30], chemical/biochemical sensing [31][32][33] and theranostics [34,35] mostly as nano-or microparticles, but also in core/shell formats or in combination with other properties such as magnetic ones [36,37]. Whereas typical microporous materials are crystalline framework solids, such as zeolites [38] with pore dimensions between 10-14 Å [39,40], mesoporous silica materials of the MCM-41 type, discovered in 1992 by researchers of the Mobil Research and Development Corporation ...…”

Fly ash-, foundry sand-, clay-, and pumice-based metal oxide nanocomposites as green photocatalysts

“…Water pollution has become one of the most serious concerns that Earth will face during the 21 st century. 1,2 It poses a great threat to human health, the aquatic ecosystem, and economic growth through unknown long-term impacts caused by the presence of emerging pollutants, e.g., personal care products, industrial/household chemicals, pharmaceuticals, and pesticides in water bodies. 3,4 In a report carried out by WHO (World Health Organization) in 2015, approximately 1.7 million people lost their lives because of consumption of contaminated water and nearly 4 billion cases of serious health problems caused by water-related diseases annually.…”

“…5 It was also estimated that half of the world's population will sustain their livings in waterstressed areas by 2025. 2,5 Thus, the driving forces for sustainable development must be associated with advanced water treatment techniques. Effective removal of emerging pollutants from wastewater before the eventual discharge into streams is a must to drive water pollution prevention.…”

Construction of Z-scheme NiO/NiC/g-C3N4composites using NiC as novel cocatalysts for the efficient photocatalytic degradation

“… 6 Among these wastewater treatment methods, photocatalytic degradation involving advanced oxidation processes is an energy-saving and highly effective technology using efficient photocatalysts under light irradiation. 7 The photocatalytic behavior is mainly determined by the quality of the photocatalyst; hence, various semiconductor-based materials have been explored for the photocatalytic degradation of organic pollutants.…”
