Activate carbon impregnated with a mixture of copper oxide and zinc oxide performs well as active adsorber for NO2 removal in automotive cabin air filters. The oxide-loaded activated carbon exhibits superior long-term stability in comparison to pure activated carbon as has been shown in previous studies. The carbon material was loaded only with 2.5 wt% of each metal oxide. Characterization of t...

in this study, zno nanoparticles were loaded on activated carbon prepared from almond shell (zno-np-ac). then, this novel material applied as an efficient adsorbent for the ultrasonic assisted simultaneous removal of basic blue 41(bb41) and basic red 46 (br46) in binary solution.  the efficiency of proposed activated carbon was enhanced by acid treatment and subsequent modification by physical ...

Metal–support interaction strongly influences the catalytic properties of metal-based catalysts. Here, titanium nitride (TiN) nanospheres are shown to be an outstanding support, for tuning electronic property platinum (Pt) nanoparticles and adjusting morphology indium sulfide (In2S3) active components, forming flower-like core–shell nanostructures (TiN-Pt@In2S3). The strong metal–support betwee...

This paper presents a facile and efficient way to prepare carbon nanofibers ornamented with Au nanoparticles (Au/CNFs). Gold nanoparticles were first deposited in the channels of an anodized aluminum oxide (AAO) membrane by thermal decomposition of HAuCl4and then carbon nanofibers were produced in the same channels loaded with the Au nanoparticles by decomposition of sucrose at 230 °C. An elect...

Improving natural photosynthesis can enable the sustainable production of chemicals. However, neither purely artificial nor purely biological approaches seem poised to realize the potential of solar-to-chemical synthesis. We developed a hybrid approach, whereby we combined the highly efficient light harvesting of inorganic semiconductors with the high specificity, low cost, and self-replication...

ABSTRACT. In this work, an activated carbon composite made with magnesium oxide nanoparticles (MgONP-AC) was effectively utilized for methyl orange (MO) adsorption. The effect of pH (6-10), mass MgONP-AC (0.1-0.3 g/L), initial MO concentration (10-30 mg/L), and temperature (283-323 K) on removal investigated using a central rotatable experimental design based the response surface technique (RSM...

Recent advances in nanotechnology could facilitate the production of cheaper solar cells. This review describes synthetic routes to various nanostructured materials that are potentially useful in photovoltaic applications. We have focused on materials that are based on earth abundant elements and/or those that are held to have lower toxicity. Methods to synthesize binary chalcogenides with vari...

The our main goal of the present research is evaluating the performance of MnO2 nanoparticles-AgX zeolite composite as a novel adsorbent catalyst for the decontamination reactions of two most known sulfur mustard simulants; 2-chloroethyl phenyl sulfide (2-CEPS), 2-chloroethyl ethyl sulfide (2-CEES) at room temperature and monitoring by Gas chromatography flame ionization detector (GC-FID) and G...

This study focus on the preparation of two supports including activated carbon derived from medlar and Palladium nanoparticles loaded on activated carbon (Pd-NP-AC). Subsequently, both adsorbent modified with a novel Schiff base chelating agent and their potential applicability for determination of trace amounts of metal ions from aqueous solution has been investigated. The method is based on c...
