Dynamics of CrO3–Fe2O3 catalysts during the high-temperature water-gas shift reaction: molecular structures and reactivity [PDF]

open access: yes, 2016
A series of supported CrO3/Fe2O3 catalysts were investigated for the high-temperature water-gas shift (WGS) and reverse-WGS reactions and extensively characterized using in situ and operando IR, Raman, and XAS spectroscopy during the high-temperature WGS/

Ammonia production by microbubbles: A theoretical analysis of achievable energy intensity

open access: yesUltrasonics Sonochemistry
The present paper studies the energy intensity of ammonia production by a freely oscillating microbubble placed in an infinite domain of liquid. The initial content of the bubble is a mixture of hydrogen and nitrogen.

The roots of organic agriculture [PDF]

open access: yes, 2012
It was concern about the replacement of traditional organic fertilizers by the then new chemical fertilizers that precipitated the early stirrings of disquiet about the prevailing direction of agriculture and which has grown into today’s organic ...

Low temperature plasma-catalytic NOx synthesis in a packed DBD reactor: effect of support materials and supported active metal oxides [PDF]

open access: yes, 2016
The direct synthesis of NOx from N2 and O2 by non-thermal plasma at an atmospheric pressure and low temperature is presented, which is considered to be an attractive option for replacement of the Haber-Bosch process.

Ruthenium‐Based Catalysts Supported on Lanthanum and Carbon‐Modified Alumina for Low‐Pressure Ammonia Synthesis

open access: yesCarbon and Hydrogen, EarlyView.
We proposed a new “hydrogen transfer–desorption” synergistic regulation strategy and developed a Ru/Al2O3‐La‐C catalyst with dual functions. La‐O sites were constructed and carbon components were introduced into the catalyst to regulate the two key steps of hydrogen transfer and desorption on the catalyst surface, respectively, solving the problem of ...
