Methanation of Carbon Dioxide over Zeolite-Encapsulated Nickel Nanoparticles

A comparative study on the kinetics of carbon dioxide methanation over bimetallic and monometallic catalysts

In this paper, Ni/Al and La-Ni/Al catalysts were prepared with a co-impregnation method and employed in carbon dioxide methanation reaction. The catalytic results showed that the catalyst with (10wt.%) of lanthanum and (20wt.%) nickel had the highest activity at low temperatures in CO2 methanation and the La-Ni/Al catalysts changed the reaction path by lowering its activation energy and consequ...

Core–shell titanium dioxide /carbon nanofibers decorated nickel nanoparticles as supports for electrocatalytic oxidation of ethanol

Abstract Recently alcohol fuel cells has been increased consideration because of their environmental friendliness, high energy conversion efficiency and low emissions. Many effort have been made to improve the electro-oxidation performance of alcohols such as methanol, ethanol and propanol. In this work, a new method for ethanol oxidation based on core–shell titanium dioxide / carbon nanofib...

Encapsulated liquid sorbents for carbon dioxide capture.

Drawbacks of current carbon dioxide capture methods include corrosivity, evaporative losses and fouling. Separating the capture solvent from infrastructure and effluent gases via microencapsulation provides possible solutions to these issues. Here we report carbon capture materials that may enable low-cost and energy-efficient capture of carbon dioxide from flue gas. Polymer microcapsules compo...

Substrate size-selective catalysis with zeolite-encapsulated gold nanoparticles.

Over the years, many strategies have been developed to address the problem of sintering of nanoparticle catalysts, including encapsulating metal nanoparticles in protective shells, and trapping nanoparticles in the cavities of certain zeolites in post-synthesis steps. In general, materials that contain metal nanoparticles that are only accessible via zeolite micropores are intriguing, specifica...
