“…Gelatin has carboxyl, hydroxyl, and amino groups in its structure (Chen et al, 2014). By combining gelatin and siloxane, gelatin-siloxane hybrid composites (GSHC) were created (Wojciechowska & Cierpiszewski, 2022). During the preparation of GSHC, -NH 2 and -COOH groups of gelatin were chemically synthesized with siloxane.…”

To deal with emergencies like water shortages and water pollution, scientists have worked on making materials and technologies that function well enough. The current technologies are not ‘100%’ efficient at providing potable water. Therefore, it is essential to come up with new and better ways to purify water. Nanotechnology offers inventive water treatment techniques. Nanomaterials are fabricated with useful properties for adsorption, catalysis, sensing, and optoelectronics applications, such as reactivity, high-aspect ratio, controlled pore volume as well as electrostatic, hydrophilic, and hydrophobic interactions. Anions, metal ions, microorganisms, and organic compounds can be eliminated using nanoparticles (NPs). Minimal NP concentrations are required for water treatment, making their application cost-effective. Biopolymeric materials have a number of advantages over their synthetic counterparts due to their easy biodegradability and low impact on the environment. Because of their minimum toxicity, improved adsorption capability, excellent biodegradability, significant photocatalytic potential and biocompatibility, nanobiohybrids have a significant role in the field of water and wastewater treatment. This chapter summarizes various production methods of diversified nanobiohybrids synthesized in recent years, with a particular focus on nanobiocomposites.

“…Low cost industrial and agricultural by-products and waste materials usually have low adsorption efficiency because of their low pore volumes and poor pore structure [ 2 , 3 ]. Novel nanomaterials, including carbon-based nanomaterials, metal-oxide based nanomaterials, nanoparticles and various nanocomposites have been systematically applied for the removal of heavy metal ions from wastewater [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ].…”

In this work, the synthesis of ordered mesoporous silica of MCM-41 type was investigated aimed at improving its morphology by varying the synthesis conditions in a one-pot process, employing different temperatures and solvent conditions. 2-methoxyethanol was used as co-solvent to ethanol. The co-solvent ratio and the synthesis temperature were varied. The pore morphology of the materials was characterized by nitrogen porosimetry and small angle neutron scattering (SANS), and the particle morphology by transmission electron microscopy (TEM) and ultra-small angle neutron scattering (USANS). The thermal behavior was investigated by simultaneous thermogravimetry-differential scanning calorimetry (TG-DSC) measurements. The SANS and N2 sorption results demonstrated that a well-ordered mesoporous structure was obtained at all conditions in the synthesis at room temperature. Addition of methoxyethanol led to an increase of the pore wall thickness. Simultaneously, an increase of methoxyethanol content led to lowering of the mean particle size from 300 to 230 nm, according to the ultra-small angle scattering data. The ordered porosity and high specific surfaces make these materials suitable for applications such as adsorbents in environmental remediation. Batch adsorption measurements of metal ion removal from aqueous solutions of Cu(II) and Pb(II) showed that the materials exhibit dominantly monolayer surface adsorption characteristics. The adsorption capacities were 9.7 mg/g for Cu(II) and 18.8 mg/g for Pb(II) at pH 5, making these materials competitive in performance to various composite materials.

“…Silica hybrid gels are among the so-called organic modified silica (ORMOSILs). Nowadays, these materials are being used for multiple applications such as the adsorption of metals in water [ 1 , 2 , 3 ], catalyst support [ 4 , 5 , 6 ], support for luminescent compounds [ 7 , 8 , 9 ], anti-corrosive or fungicide coatings [ 10 , 11 , 12 , 13 ], and biomedicine [ 14 , 15 , 16 , 17 , 18 , 19 ]. The key behind the tunability of the properties of these materials is the synergetic effect that generates the coexistence, at a nanometric scale, of an inorganic skeleton with flexible and functional organic constituents [ 20 , 21 ].…”

The search for new materials with improved properties for advanced applications is, nowadays, one of the most relevant and booming fields for scientists due to the environmental and technological needs of our society. Within this demand, hybrid siliceous materials, made out of organic and inorganic species (ORMOSILs), have emerged as an alternative with endless chemical and textural possibilities by incorporating in their structure the properties of inorganic compounds (i.e., mechanical, thermal, and structural stability) in synergy with those of organic compounds (functionality and flexibility), and thus, bestowing the material with unique properties, which allow access to multiple applications. In this work, synthesis using the sol-gel method of a series of new hybrid materials prepared by the co-condensation of tetraethoxysilane (TEOS) and 4-chlorophenyltriethoxysilane (ClPhTEOS) in different molar ratios is described. The aim of the study is not only the preparation of new materials but also their characterization by means of different techniques (FT-IR, 29Si NMR, X-ray Diffraction, and N2/CO2 adsorption, among others) to obtain information on their chemical behavior and porous structure. Understanding how the chemical and textural properties of these materials are modulated with respect to the molar percentage of organic precursor will help to envisage their possible applications: From the most conventional such as catalysis, adsorption, or separation, to the most advanced in nanotechnology such as microelectronics, photoluminescence, non-linear optics, or sensorics.
