“…The intrigue of nanotechnology is the ability to control the manipulation of nanoscale (approximately 1 nm to 100 nm) structured materials and integrate them into large material components, systems, and architecture that have novel properties and functions [2,86,113,114]. The merits of using semiconductor photocatalysts in their nanorange far outweigh their use in their bulk form [115]. For example, in the case of adsorption where surface sites of the adsorbent are utilised, diffusion is usually hindered due to the lack of a porous structure in the bulk materials.…”

The presence of both organic and inorganic pollutants in water due to industrial, agricultural, and domestic activities has led to the global need for the development of new, improved, and advanced but effective technologies to effectively address the challenges of water quality. It is therefore necessary to develop a technology which would completely remove contaminants from contaminated waters. TiO2(titania) nanocatalysts have a proven potential to treat “difficult-to-remove” contaminants and thus are expected to play an important role in the remediation of environmental and pollution challenges. Titania nanoparticles are intended to be both supplementary and complementary to the present water-treatment technologies through the destruction or transformation of hazardous chemical wastes to innocuous end-products, that is, CO2and H2O. This paper therefore explores and summarizes recent efforts in the area of titania nanoparticle synthesis, modifications, and application of titania nanoparticles for water treatment purposes.

“…When the liquid itself acts as a stabilizer, the metal vapour can condense with the solvent vapour, giving a solid matrix. [40] Other less common methods include redox surface techniques, [41,42] thermal [43] and photochemical [44] decomposition of metal complex precursors, sonochemical synthesis [45] and laser ablation.

This perspective examines the state-of-the-art of catalysis by metal nanoparticles. We outline various methods for preparing metal nanoparticle suspensions, and highlight the role of the stabilizers and the stabilizing principles. Subsequently, we examine some catalytic applications of homometallic and bimetallic nanoparticle suspensions in a variety of reactions. The cases are divided according to the stabilizing agent: polymers, dendrimers, ionic liquids, surfactants, micelles and micoremulsions, ligands and solid supports. We explain the importance of atom/ion leaching (all too frequent in nanoparticle catalysis, especially for the catalytically active group VIII metals) and consider ways of minimizing it. The future perspectives of nanoparticles as catalysts are discussed.

“…Semiconductor materials have been alluring scientists because of their possession of novel characteristics and potential applications [20,21]. Various studies have established that semiconductor photocatalysts in their nano range are more beneficial than their bulk counterparts [22]. The reduction of the size of a material to nanoscale gives rise to new chemical and physical properties [2].…”
