“…For comparison, the photocatalytic experiments using bare TiO 2 and Ag 3 PO 4 were also conducted under the same experiment conditions. Temperature, 37 acidity, 38 reaction time, 39 and doping amount 40,41 are all important factors that could affect the photocatalytic activity. In this study, we controlled other variables to be constants to explore the effect of doping amount on the photocatalytic activity of the composite catalyst.…”

Efficient conversion of carbon dioxide (CO 2) into energy-bearing compounds using abundant solar energy is a promising technique that simultaneously responds to the concerns on global warming and energy shortage. The purpose of this study was to find a photocatalyst that can efficiently utilize sunlight for an efficient reduction of CO 2 to energy-bearing carbon monoxide (CO). Silver phosphate/titanium dioxide (Ag 3 PO 4 /TiO 2) hetero-structured photocatalysts with different mole ratios of Ag 3 PO 4 to TiO 2 were synthesized by a facile precipitation method, and for the first time used for photocatalytic CO 2 reduction by water vapor (H 2 O). When the mole ratio of Ag3PO4 to TiO 2 was 0.15, the as-synthesized photocatalyst exhibited the highest CO 2 reduction activity under ultraviolet (UV) and visible light irradiation, with the productivity of CO reaching as high as 74.84 μmolÁg −1 within a 3-h experiment. This is 3.5 and 11.7 times higher than that for the bare Ag 3 PO 4 and TiO 2 , respectively. The characterization results indicate that a heterojunction was formed between Ag 3 PO 4 and TiO 2 , which significantly promoted the photocatalytic CO 2 reduction reactions through facilitating the separation and migration of the photogenerated charge carriers. This study verified that the Ag 3 PO 4 /TiO 2 catalyst can effectively utilize solar energy for reduction of CO 2 to CO.

“…The presence of an -OH group in the ortho position significantly influences the increase in the antioxidant properties of phenolic acids [9]. Chlorogenic acid present in A. europaeum is highly effective in inhibiting the oxidation of LDL in vitro, which is comparable with the activity of caffeic acid [10,11]. Figure 3 shows the chemical structure of active compounds present in A. europaeum : (A) Chlorogenic acid, (B) Caffeic acid, (C) Eugenol and (D) Asaron.…”

“…Various chemical and physical treatment methods, such as coagulation, precipitation filtration, membrane separation, electrodialysis, biological treatment, oxidation and adsorption, have been used for the removal of dyes from wastewater [10]. The photocatalytic degradation of organic as well as inorganic dyes is a promising and ambitious technology, which has a strong effect on the removal of different dyes existing in wastewater [11]. It is well-known that the size of metal nanoparticle plays an important role in catalytic reduction, and that nanoparticles exhibit size-dependent catalytic properties [12].…”

Nanomaterials have attracted much attention in the recent years. The biological synthesis of metal nanoparticles is an important area of research in nanotechnology. This work describes a biological method for the synthesis of Au-Pt nanoparticles using the aqueous extract of Asarum europaeum. The synthesized Au-Pt nanoparticles were characterized by UV-Vis, scanning electron microscopy (SEM) with EDS profile, Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM) and atomic force microscopy (AFM). The applied methods made it possible to determine the presence of Au-Pt nanoparticles sized 5-6 nm. The EDS profile shows a gold and platinum signal confirming the formation of Au-Pt nanoparticles. The synthesized Au-Pt nanoparticles were used as a catalyst for the remediation of malachite green and methylene blue. Base on the obtained results, the Au-Pt nanoparticles synthesized using Asarum europaeum showed good catalytic activity in the reduction of methylene blue and malachite green.

“…The dangerous dyes that contaminated water were break from the active sites of the photocatalysts by photogenerated charge carriers . The high activity and visible responsive photocatalyst have been commonly used and explored new achievements by directly using solar light . The production of hydrogen energy takes place by the irradiation of solar light on the photocatalytic material to stimulate the electrons from the VB and move towards the CB by absorbing the energy and generating hydrogen gas along with hydroxide radicals .…”

Summary Hydrogen energy production and dyes degradation have been considered the need of modern age of technology in globe irrespective of the level of science and research in that country. Hydrogen gas is a green energy fule for the future application and abunduntly available in environment. Various techniques are reported for the production of hydrogen energy among which photocatalysis method is envirnmental friendly, cost‐efficient method using water that also decontaminated from dyes, which is a main problem nowadays because of increase in industrial applications according to the living standards. The composite of Bismuth vanadate (BiVO4) with the coupling of the rduced graphene oxide (rGO) were synthezied by the facial hydrothermal technique by using a bismuth nitrate penta hydrate and amonium metavanadate as main precour and graphene oxide solution for reduced graphene oxide incorporation. X‐ray diffraction (XRD), Scanning Electron Microscope (SEM), ultraviolet adsorption spectroscopy (UV‐vis), and Brunauer‐Emmett‐Teller (BET) characterization tools investigate the role of concentration of the coupling material rGO in BiVO4. All characterization techniques confirms that 1.5% rGO/BiVO4 shows transformation of tetragonal to monoclinic phase with altration of the particles size (25‐40 nm), with high‐surface area, having irregular spherical porous clusters degradation of methelene blue (97%), production of green energy in the form of hydrogen gas fuel, and enhancement of the absorption of light that is clear intimation of the high photocatalytic efficiency towards the decontamination of the wastewater and production of hydrogen gas. Prepared nanostructured composite in current work reveals effective photocatalytic activity for decontamination of the wastewater and evolution of hydrogen energy would be the precise idea to utilize them in near future with various promising applications.
