Heavy metal ions and organic pollutants cause irreversible damage to water environment, thereby posing significant threats to the well-being of organisms. The techniques of adsorption and photocatalytic degradation offer versatile solutions for addressing water pollution challenges, attributed to their inherent sustainability and adaptability. Silicates exhibit exceptional practicality in the realm of environmental protection owing to their structural integrity and robust chemical/thermal stability during hybridization and application process. Furthermore, the abundance of silicate reserves, coupled with their proven effectiveness, has garnered significant attention in recent years. This detailed review compiles and analyzes the extensive body of literature spanning the past six years (2018-2023), emphasizing the pivotal discoveries associated with employing silicates as water purification materials. This review article provides a comprehensive overview of the structure, classification, and chemical composition of diverse silicates and offers a thorough descriptive analysis of their performance in eliminating pollutants. Additionally, the utilization of diatomite as either precursors or substrates for silicates, along with the exploration of their corresponding purification mechanisms is discussed. The review unequivocally verifies the efficiency of silicates and their composites in the effective elimination of various toxic pollutants. However, the development of novel silicates capable of adapting to diverse environmental conditions to enhance pollution control, remains an urgent necessity.

“…Both Mo-alloying and P-doping modify the D-band density of Ni, optimizing *H bond strength and reducing energy barriers for the adsorption of intermediate species, ultimately leading to reduced energy barriers for water splitting [92]. In the study conducted by the He group; an innovative approach was employed utilizing urea and carbon nanotubes to decorate MOGs with iron (Fe) as a novel sacrificial precursor (Figure 6) [93,94]. This method facilitated the synthesis of Fe-Fe 2 O 3 nanoparticles embedded within an N-doped carbon matrix, aimed at enhancing the oxygen reduction reaction (ORR) catalysis.…”

Gel-based materials have garnered significant interest in recent years, primarily due to their remarkable structural flexibility, ease of modulation, and cost-effective synthesis methodologies. Specifically, polymer-based conductive gels, characterized by their unique conjugated structures incorporating both localized sigma and pi bonds, have emerged as materials of choice for a wide range of applications. These gels demonstrate an exceptional integration of solid and liquid phases within a three-dimensional matrix, further enhanced by the incorporation of conductive nanofillers. This unique composition endows them with a versatility that finds application across a diverse array of fields, including wearable energy devices, health monitoring systems, robotics, and devices designed for interactive human-body integration. The multifunctional nature of gel materials is evidenced by their inherent stretchability, self-healing capabilities, and conductivity (both ionic and electrical), alongside their multidimensional properties. However, the integration of these multidimensional properties into a single gel material, tailored to meet specific mechanical and chemical requirements across various applications, presents a significant challenge. This review aims to shed light on the current advancements in gel materials, with a particular focus on their application in various devices. Additionally, it critically assesses the limitations inherent in current material design strategies and proposes potential avenues for future research, particularly in the realm of conductive gels for energy applications.

The presence of organic dyes in aqueous environments is of extreme hazardousness against life due to the toxicity of these compounds. Thus, its removal from these various aquatic media is of the utmost importance and several technologies are constantly proven to match this goal. Among these technologies, various types of degradation and adsorption are the most widely used, and of the various types of materials used within these technologies, nanomaterials are constantly developed and investigated, probably due to the various properties that these nanomaterials presented. This work reviewed recent developments (2023 year) about the use of these nanomaterials on the treatment of solutions contaminated with these toxic organic dyes.
