Metal nanoparticles decorated mint-cellulose acetate composite as an efficient catalyst for the reduction of methyl orange.

Water contamination caused by toxic compounds has emerged as one of the most severe challenges worldwide. Biomass-based nanocomposites offer a sustainable and renewable alternative to conventional materials. In this study, a nanocomposite of mint and cellulose acetate (Mint-CA) was prepared and employed as a supportive material for Cu nanoparticles (CuNPs) and Ag nanoparticles (AgNPs).

SnAgO-Coated Adhesive Tape as a Recyclable Catalyst for Efficient Reduction of Methyl Orange.

Silver oxide-doped tin oxide (SnAgO) nanoparticles were synthesized and different spectroscopic techniques were used to structurally identify SnAgO nanoparticles. The reduction of 4-nitrophenol (4-NP), congo red (CR), methylene blue (MB), and methyl orange (MO) was studied using SnAgO as a catalyst. Only 1.

Adsorptive removal of heavy metals and organic dyes by sodium alginate/coffee waste composite hydrogel.

Heavy metals and dyes used in technological applications have a detrimental influence on human health and the environment. The most used methods for removing pollutants depend on high-cost materials. Therefore, this research was conducted on cost-effective alternatives derived from natural resources and food waste.

Adsorption efficiency of date palm based activated carbon-alginate membrane for methylene blue.

In the current study, activated carbon (AC) was prepared from date palm using single step activation using boric acid as an activating agent. The synthesized AC was incorporated with alginate (AC-alginate (AC-alg)) to prepare membrane for adsorption of methylene blue (MB) in batch adsorption study. The prepared membrane was characterized using different types of analytical techniques such as FTIR, SEM, and TGA analysis.

Synthesis of Activated Carbon from Seeds for the Removal of Cationic and Anionic Dyes.

The removal of dyes from industrial effluents is one of the most important industrial processes that is currently on academic demand. In this project, for the first time, seeds are used as biosources for the synthesis of activated carbon (AC) using physical as well as acid-base chemical methods. The synthesized AC was initially characterized by different instrumental techniques, such as FTIR, BET isotherm, SEM, EDX and XRD.

Chitosan@Carboxymethylcellulose/CuO-CoO Nanoadsorbent as a Super Catalyst for the Removal of Water Pollutants.

In this work, an efficient nanocatalyst was developed based on nanoadsorbent beads. Herein, carboxymethyl cellulose-copper oxide-cobalt oxide nanocomposite beads (CMC/CuO-CoO) crosslinked by using AlCl were successfully prepared. The beads were then coated with chitosan (Cs), Cs@CMC/CuO-CoO The prepared beads, CMC/CuO-CoO and Cs@CMC/CuO-CoO, were utilized as adsorbents for heavy metal ions (Ni, Fe, Ag and Zn).

Alginate/Banana Waste Beads Supported Metal Nanoparticles for Efficient Water Remediation.

Water pollution is considered a perilous issue that requires an immediate solution. This is largely because of the strong correlation between the global population increase and the amount of waste produced (most notably food waste). This project prompts the conversion of food waste into useful materials that can be used with sodium alginate as a catalytic support for metal nanoparticles.

Sodium alginate nanocomposite based efficient system for the removal of organic and inorganic pollutants from wastewater.

An effective and selective catalytic system based on cerium oxide-stannous oxide (CeO-SnO) wrapped Na-alginate hydrogel was developed for the selective reduction of potassium ferricyanide (K[Fe(CN)]). Na-alginate hydrogel was used as a reacting container for CeO-SnO nanoparticles. Na-alginate wrapped CeO-SnO (Alg/CeO-SnO) was applied as a catalyst and examined toward the reduction of several hazardous pollutants, such as nitrophenols, dyes and K[Fe(CN)].

Development of alginate@tin oxide-cobalt oxide nanocomposite based catalyst for the treatment of wastewater.

In this study, tin oxide‑cobalt oxide nanocatalyst was prepared by a simple method, which grew in spherical particles with an average diameter of 30 nm. Tin oxide-cobalt oxide was further wrapped in alginate polymer hydrogel (Alg@tin oxide-cobalt oxide), and both materials were utilized as nanocatalysts for the catalytic transformation of different pollutants. Tin oxide-cobalt oxide and Alg@tin oxide-cobalt oxide nanocatalysts were tested for the catalytic reduction of 4-nitrophenol, congo red, methyl orange, methylene blue (MB) and potassium ferricyanide in which sodium borohydride was used as a reducing agent.
