Catalytic ammonia decomposition over Ni-Ru supported on CeO2 for hydrogen production: Effect of metal loading and kinetic analysis
(Elsevier Science, 2021-06-05)
Ceria-supported Ni-Ru bimetallic catalysts with different metal loadings have been prepared by co-impregnation, characterized and tested in the production of hydrogen from the catalytic decomposition of ammonia. The ...
Larval development of the giant river prawn Macrobrachium rosenbergii at different ammonia concentrations and pH values
(2005-03-01)
The effect of ammonia and pH levels on giant river prawn Macrobrachium rosenbergii larvae were evaluated to provide science-based information on safe levels of ammonia and pH for larviculture. Survival rate, developmental ...

Stress in pacu exposed to ammonia in water
(Sociedade Brasileira de Zootecnia, 2012-07-01)
The present study evaluated stress indicators in pacu exposed to ammonia in water under the following conditions: without NH4Cl (0.00 g/L); with 0.0078 g NH4Cl/L; and with 0.078 g NH4Cl/L (pH 8.3 and 27 ºC). After the salt ...
Iridium−Rhodium Nanoparticles for Ammonia Oxidation: Electrochemical and Fuel Cell Studies
(2017-05-01)
This study reports the use of carbon-supported IrRh/C electrocatalysts with different iridium-to-rhodium atomic ratios (0 : 100, 50 : 50, 70 : 30, 90 : 10, and 100 : 0) for ammonia electro-oxidation (AmER) in alkaline ...
AlGaN double-walled nanotubes as ammonia gas sensor
(2020-12-01)
Nanotubes are one-dimensional material that has been proposed for many different applications, i.e. electronic devices and gas sensor. Due to their reduced size, extended surface area and stability they can represent an ...
Ammonia borane dehydrogenation tendencies using Pt4, Au4, and Pt2Au2 clusters as catalysts
(Elsevier B.V., 2019)
Small metallic clusters -mediated gas phase catalysis studies give lights to understand simple and complex catalytic processes, and help in the discovery and explanation of non-traditional “molecular-scale” catalytic ...
