Photoelectrocatalysis is a hybrid photon/electron-driven process that benefits from the synergistic effects of both processes to enhance and stabilize generation disinfecting oxidants. an easy operate technology can be scaled-up or scaled-down for various water treatment applications as low-cost decentralized systems. This review article describes fundamentals photoelectrocatalysis, applied dis...

in this paper, tin dioxide nanoparticles were synthesized by a fast and simple co-precipitation method. for sno2 preparation, we used ammonia as precipitation agent and bis (acetylacetone) ethylene diamineas as capping agent. by changing in sncl4, acacen mole-ratio different morphologies were obtained. this semiconductor nanostructure has photo-catalyst activities and can degrade organic dyes a...

we report on the synthesis, morphology, chemically and structurally of la2o3-co3o4-zro2 nanostructure. the la2o3-co3o4-zro2 nanostructure was synthesized by a method based on the co-precipitation. composite powders have been characterized by xrd (x-ray diffraction), sem (scanning electron microscopy) and bet (brunauer-emmett-teller). x-ray diffraction showed the formation of nano crystalline, l...

A simple, time effective and cost effective, methos was reported for synthesis of nickel oxide nanostructure. The NiO nanostructure was synthesized by gamma-irradiation method from NiSO4 precursor. The solution was irradiated by 60Co gamma-ray source at the dose rate of 40 Gy/min for determined time. The synthesized powders are characterized by means of X-ray powder diffraction (XRD), Energy-di...

in the present study we search potential of pt-decorated graphene (ptg) as a new nanostructure adsorbent for nitrous oxide (n2o) using density functional theory (dft). after fully relaxation of different possible orientations of n2o-ptg complex, we distinguished two optimized configurations for this system; 1- terminal n-side of gas is oriented towards pt so that the molecule axis is perpendicu...

this paper reports the synthesis of polypyrrole coated sno2/znoelectrospunnanofibers via vapor phase polymerization method. in order to prepare one dimensional (sno2-zno)/polypyrrole with the core sheath structure, first sno2-zno composite nanofibers were synthesized via electrospinning method followed by adsorption of fe3+ on the surface of the sno2-zno nanofibers and finally pyrrole was polym...

In this paper, we report a high-performance self-supported supercapacitor electrode composed of cracked bark-shaped Ni-Co-Mn ternary metallic sulfide (NiCoMnS4) nanostructure on carbon cloth prepared by simple one-step hydrothermal process and subsequent electrochemical treatment. The delivers high specific discharge capacity up to 2470.4 F g−1 at 1 A rate performances 1635.6 10 910.2 even 32 g...

Constructing nanostructure through exsolution has been demonstrated as an effective approach to producing electrode materials with superior performance and stability in the application of solid oxide cells (SOCs), primarily due excellent catalytic properties significantly enhanced offered by well-embedded nanoparticles that are exsolved from a supporting oxide. Here, we focus on investigating t...

Fossil fuels are the main sources of human energy, but their combustion releases toxic compounds sulfur oxide. In oil industry, using optimal methods to eliminate from fossil is a very important issue. this study, performance montmorillonite/graphitic carbon nitride (a new hybrid nanostructure) in increasing biodesulfurization activity Rhodococcus erythropolis IGTS8 was investigated. X-ray diff...
