“…The metal oxides also enhance the separation properties of titania suspended particles from solution and thus decrease the effect of beam splitting by agglomerated particles [118]. Moreover, the metal oxides act as supports of the catalysts [10]. However, some of the metal oxides are thermodynamically unstable, for example, RuO 2 / TiO 2 , thus resulting in electron-hole pair recombination and significantly decreasing the photocatalytic activity [95].…”

“…Water pollutants can be classified as physical (odour, colour, solids, or temperature), biological (pathogens), or chemical (organic or inorganic compounds) [1,2,[5][6][7][8][9]. Organic pollutants are of more concern than the other types because of their carcinogenic and mutagenic effects even after exposure to minute concentrations [10,11].…”

“…The ubiquitous appearance of organic contaminants in sewage effluents, groundwater, drinking water, and sludge poses a significant 2 Journal of Nanomaterials threat to humans and aquatic organisms [14]. Volatile organic compounds (VOCs) are known to be toxic and carcinogenic and have been implicated in the depletion of the stratospheric ozone layer while also contributing to global warming [10,15]. These pollutants have been reported as being mutagenic and hence are responsible for the emergence of antibiotic resistance bacteria and genes [16].…”

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.

“…Many times, water treatment processes may lead to the formation of carcinogenic or mutagenic disinfection by-products (DBPs), for example haloacetic acids (HAAs), as a result of reactions occurring between natural organic matter and disinfectants such as chlorine or chloramines [7]. Organic impurities need more attention in comparison to the others as they have prevalent carcinogenic impacts, even upon being exposed to minimal amounts [8,9]. The organic dyes are usually distinguished depending on their chromophore group [10].…”

Cerium doped zirconia (ZrO2) nanoparticles are used in the electrochemical investigation of one of the important neurotransmitter Dopamine. Cerium doped ZrO2 nanoparticles finds an interesting application for the electrochemical detection of Dopamine. These cerium doped zirconia nanoparticles were synthesized by environmental benign co‐precipitation method. The phase formation and the crystallinity of the synthesized nanoparticles were characterized by X‐ray diffraction and it was in cubic phase. The morphology of the nanoparticles was characterized by field‐emission scanning electron microscopy and the particle size was measured by using high resolution transmission microscopy. The average particle size was measured to be 18 nm. Additionally, the effectiveness of cerium doped zirconia nanoparticles modified carbon paste electrode (Ce‐ZrO2/MCPE) was evaluated by using cyclic voltammetric technique, to assess the application as electrochemical sensor for Dopamine. Differential pulse voltammetry method is used for the detection of Dopamine, the limit of detection was found to be 3.6 μmol L−1 based on (S/N=3). This shows high stability and low detection level at modified electrode. In addition, modified electrodes are also been used the detection of Dopamine in real time sample analyses with satisfactory results.
