Geothermal water is a clean, cheap and renewable resource and it is widely distributed all over the world. In this work, ternary Ag2CO3/Ag/AgCl photocatalyst has been successfully synthesized via a one-pot precipitation method in natural geothermal water at room temperature, wherein the geothermal water serves as the source of chlorine and carbonate. The(More)
Herein, the generation of gold, silver, and silver-gold (Ag-Au) bimetallic nanoparticles was carried out in collagen (gelatin) solution. It first showed that the major ingredient in gelatin polypeptide, glutamic acid, acted as reducing agent to biomimetically synthesize noble metal nanoparticles at 80°C. The size of nanoparticles can be controlled not only(More)
In this report, we rationally designed and fabricated P-C3N4/ZnIn2S4 nanocomposites by in situ immobilizing ZnIn2S4 nanosheets onto the surface of mesoporous P-doped graphite carbon nitrogen (P-C3N4) nanosheets in a mixed solvothermal environment; their application to the photoreduction of 4-nitroaniline was used to estimate the photocatalytic performance.(More)
A widely soluble graphene oxide sheets decorated by silver nanoprisms were prepared through green synthesis at the room temperature using gelatin as reducing and stabilizing agent. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-visible spectroscopy and fluorescence(More)
Hydrogen production through water splitting using photocatalysts with solar energy can produce clean fuel from renewable resources. In this study, CdS nanoparticle sensitized attapulgite (ATP) nanocomposites were successfully prepared by a facile approach. Under visible-light irradiation, the as-prepared photocatalysts were used for photocatalytic water(More)
The freestanding Sb(2)S(3) films were easily synthesized at the interface of water and toluene at room temperature, where Na(2)S and (C(2)H(5)OCS(2))(3)Sb (xanthate, O-ethyldithiocarbonate) acted as sulfur and antimony source, respectively. After 3 h of aging, the Sb(2)S(3) films with a flat surface toward organic side and rough surface toward aqueous side(More)
Attapulgite (ATP), not only as a type of natural and low cost silicate clay mineral but also as a high quality nanosized material with large surface area, layered and lath-like structure, has been found to have a wide variety of industrial applications. The ideal composition of ATP is Mg5Si8O20(OH)2(OH2)4. However, according to previous reports from(More)
Aiming to monitor hydrogen peroxide and oxidizing ions in aqueous circumstance, functionalized attapulgite [i.e. gold-modified attapulgite nanocomposites (Au/ATP NCs)] as peroxidase mimics were prepared by loading β-cysteamine-capped gold nanoparticles onto attapulgite with the use of electrostatic interactions. As-prepared Au/ATP NCs were used for the(More)
In this investigation, a series of hierarchical CdIn2S4/g-C3N4 nanocomposites were firstly synthesized by a facile one-pot hydrothermal strategy, wherein the mesoporous g-C3N4 nanosheets were in-situ self-wrapped onto CdIn2S4 nanosheets. Systematic characterization by XRD, FT-IR, UV-vis DRS, SEM, TEM, HAAF-STEM, XPS, photoelectrochemical tests were employed(More)
In this work, we report a selective electrochemical sensing of nitrobenzene (NB) using an alumina (γ-Al2O3) polished glassy carbon electrode (GCE) for the first time. The scanning electron microscopy studies confirm the presence of alumina particles on the GCE surface. X-ray photoelectron spectroscopy studies reveal that the utilized alumina is γ-Al2O3. The(More)
