Nanocomposites containing titanium dioxide for environmental remediation

Abstract

Titania is considered to be one of the most versatile material in its nanoform. Scientific community looks towards it to address various pressing global problems. One such problem is aquatic pollution arising from organic chemicals such as dyes, pesticides, antibiotics etc. due to industrial, domestic and agricultural activities. Titania proves to be very effective to address this problem owing to its superior photocatalytic properties. In this review, we will review the recent advances in titania-based nanocomposites. The recent advances discussed in this review include synthesis of titania, modification of titania, exploration of various supports such as silica, carbon, graphene etc., that is documented to enhance its environmental remediation properties.

Easy way to produce iron-doped titania nanoparticles via the solid-state method and investigation their photocatalytic activity

“…The most widely used photocatalyst is titanium dioxide (TiO 2 ) [4,5] which is economic [6], non-toxic, available, chemical inert, with high photocatalytic activity [7] as claimed by many authors [8][9][10]. Schematic photochemical activation of titania is represented in Fig.…”

Multi-round recycling of green waste for the production of iron nanoparticles: synthesis, characterization, and prospects in remediation

“…In the last decade, various types of nanoparticles (NPs)-such as carbon-based-, ceramic-, semiconductor-, polymeric-, lipid-, and metal NPs [2]-have gained attention and were implemented for various purposes. Among these, metal NPs such as FeNPs, AgNPs, and TiO 2 NPs were extensively studied and their potentials in remediation were tested: as an example, AgNPs were assayed for remediation of aquatic environments from azo dyes and TiO 2 NPs were explored in converting organic pollutants to environmentally friendly by-products [3,4]. FeNPs were also considered attractive candidates, since FeNPs can remove or convert various pollutants such as chlorinated organic compounds (e.g., DDT; 1,1,1-thrichloro-2,2-bis(pchlorophenyl) ethene [5]), certain heavy metals (e.g., As and Hg [6]), and toxic inorganic compounds (e.g., nitrate [7]) to inert or non-harmful products.…”
