One-step fabrication of highly dispersed Ag nanoparticles
The preliminary investigation of the formation of Ag NPs in the resulted samples was carried out by UV–vis adsorption spectra analysis. The UV–vis adsorption spectra of GO, Ag/N-rGO heterogeneous nanostructures and Ag/N-rGO prepared without PVP were depicted in Fig. 2a. In the spectrum of GO, the peak arises from the л-л* transitions of the aromatic C C bonds centered at 229 nm, and the

Crystals | Free Full-Text | Effect of Ag/rGO
A facile hydrothermal method was employed to synthesize silver–reduced graphene oxide (Ag/rGO) plasmon-modified SnO2 composite, by incorporating Ag–reduced graphene oxide (Ag/rGO) into SnO2 nanorods as a photoanode for assembling a self-powered ultraviolet photodetector (UVPD). The as-synthesized samples were investigated in detail by X-ray diffraction (XRD), scanning electron microscopy

Colloidal Suspensions of Highly Reduced Graphene Oxide
Two different sets of solubility parameters are used to rationalize when stable colloidal suspensions of graphene oxide sheets and, separately, of reduced graphene oxide sheets in a given solvent type are possible and when they are not.
Reduced graphene oxide (RGO) falls within this class of materials and present excellent adsorptivity and conductivity, high strength and good flexibility for chemical modification [20–24]. The RGO can be reduced on various substrates and through different processes, including electrochemical and chemical processes [25, 26].
Graphene/Polyaniline Nanofiber Composites as
Chemically modified graphene and polyaniline (PANI) nanofiber composites were prepared by in situ polymerization of aniline monomer in the presence of graphene oxide under acid conditions. The obtained graphene oxide/PANI composites with different mass ratios were reduced to graphene using hydrazine followed by reoxidation and reprotonation of the reduced PANI to give the graphene/PANI
No optimal water concentration could be found for the PVA-graphene oxide nanocomposite papers, as dehydration of these structures continually enhances stiffness until a final water content of ∼7 wt % (additional water cannot be removed from the system even after 12 h of annealing).
Supercapacitors from Free-Standing Polypyrrole/Graphene
Interfacial/in situ oxidative polymerization of polypyrrole in the presence of functionalized graphene sheets produces high-quality composites for supercapacitors, as analyzed by electrochemical impedance spectroscopy and cyclic voltammetry analysis. The synergistic interaction induced by the growth of p-type polypyrrole on the surface of negatively charged carboxylate functionalized graphene

Along with its derivatives, graphene oxide (GO) and reduced graphene oxide (rGO) are two most common forms of functionalized graphene with oxygen-containing surface groups (i.e., hydroxyl, carboxyl and epoxy groups), which possess poorly defined compositions due to different degrees of oxidation .
- What is poly Aluminium chloride?
- This article delves into the chemical properties, uses, and safety considerations of poly aluminium chloride, while also examining its pivotal role in the water treatment industry. Poly aluminium chloride, commonly abbreviated as PAC, is a complex chemical compound used primarily as a coagulant in water purification.
- What is poly Aluminium chloride (PAC)?
- In the vast field of water treatment, the role of chemicals in ensuring the purity and safety of water cannot be overstated. Among these, poly aluminium chloride (PAC) has emerged as a cornerstone in both potable water and wastewater treatment processes.
- Why is poly Aluminium chloride used in water treatment?
- The primary use of poly aluminium chloride in the water treatment process is to remove impurities and clarify water. This is achieved through a process known as coagulation, where PAC helps to bind particles into larger aggregates that can be easily removed.
- What is the growth of the poly aluminum chloride market?
- The poly aluminum chloride market will generate over USD 1 billion by 2027, primarily due to the superior compatibility of its liquid form for applications, including treatment of drinking water, wastewater, swimming pool water, and industrial effluents and sewage. Water treatment is the most popular application in the market.
