We investigate the activity of cu nanoparticles for electrochemical reduction CO2 into methane. find that formation process affects Cu size-dependent activity. This finding traces a new route to design nanocatalysts.

the influence of mo particle size on the catalytic activity and product selectivity of alkalized mos2 nanocatalysts has been investigated. nanocatalysts are prepared using a microemulsion technique with water-to-surfactant ratios of 1-12. three different techniques, including xrd, tem, and hydrogen chemisorption were used to determine the molybdenum average particle size and their activity and ...

The increase in population demands for industrialization and urbanization which led to the introduction of novel hazardous chemicals our environment. most significant parts these harmful substances found water bodies remain background, causing a health risk humans animals. It is critical remove toxic from wastewater keep cleaner greener Hence, treatment challenging area days manage liquid waste...

Vulcan XC-72 samples were functionalized with methanol (MeOH) by Intermittent Microwave Heating (IMH) under different treatment conditions. To assess the effectiveness of proposed method citric acid functionalization was also performed as comparison. The obtained carbonaceous supports used to synthesize Pt/C-MeOH and Pt/C-CA nanocatalysts. surface assessed using them support for Pt/C nanocataly...

Functionalization of carbon nanotube (CNT) was performed, during preparation of Fischer–Tropsch synthesis (FTS) via cobalt nanocatalysts, to modify the surface properties of CNT support. Common and functionalized CNT supported cobalt nanocatalysts were prepared using impregnation wetness method with cobalt loading of 15 wt.%. The catalysts were characterized by Brunauer–Emmett–Teller (BET), Fou...

Strong dense many-spin interactions have been proposed to organize novel orbital dynamics (the Little Effect) for novel chemical and catalytic phenomena. The recent determinations of the relativistic and quantum Hall effects of carriers in graphene under strong magnetic confinement have substantiated the Little Effect. Moreover such nonclassical phenomena under the stronger magnetic confinement...

In this paper, we demonstrate a monolithic integrated micro direct methanol fuel cell (μDMFC) for the first time. The monolithic integrated μDMFC combines proton exchange membrane (PEM) and Pt nanocatalysts, in which PEM is achieved by the functionalized porous silicon membrane and 3D Pt nanoflowers being synthesized in situ on it as catalysts. Sulfo groups functionalized porous silicon membran...
