Transition elements catalyst and method for producing the same , as well as the selective hydrogenation processPROBLEM TO BE SOLVED: To provide a method for obtaining a catalyst having reduction activity from transition element ions except palladium, to provide a product obtained by this method, a ...
Transition metals are essential trace elements for life forms that exist in nature. Most organisms require the first row of transition metals [1] (Fig. 1a), such as Mn, Fe, Zn, etc. Except for group IIB and IB where Zn and Cu are located, the d-orbital of the transition metals are...
The distribution of the isomeric aromatic products from the dehydrocyclization of ten C 8顥窩 9 paraffins over a 0.6% Pt catalyst supported on "nonacidic" alumina has been determined. The aromatic isomers obtained experimentally are thos... BH Davis,PB Venuto - 《Journal of Catalysis》 被引量...
The OER activity of Ni-based catalysts can be significantly enhanced by doping with other earth-abundant elements such as Co, Fe, Mn, and Zn17–22. Therefore, a systematic study of the OER activities achieved when different dopants are added to Ni-based hydroxides would provide valuable ...
For all the reaction routes, the final reaction products are N-DMBI+, PDI•− and H2 gas, AuNP only serves as the reaction catalyst. PDI-C6C7 molecule is modelled by a simpler PDI in which the 1-hexylheptyl side chain is replaced by a methyl group. Extended Data Fig. 6 Gibbs ...
*The baseline consists of the EU Reference Scenario 2020 (“REF”), the main elements of which are depicted in an Annex of the impact assessment for the revision of EU ETS Directive. Show more Increasing the use of clean energy will be increasingly cost effective. Measures such as the Ene...
catalyst, alongside learning which crystallographic phases are present. XPS is a powerful tool for observing the chemical species and oxidation states present in the system; this is useful for learning which elements and ions are most beneficial for the OER. Other characterization techniques can be ...
Our survey of over 140 senior leaders indicates the change needed as leaders move from a “traditional leadership” style prioritizing elements such as planning, directing, and controlling to an “emerging leadership” approach that values a visionary style where leaders act as an architect, catalyst...
To further improve the catalytic performance of TMO on OER, introducing elemental dopants, creating vacancies, optimizing morphology, decreasing particle size, and reconstructing surface are effective strategies. The doping of foreign active elements can regulate the electronic structure of the catalyst, ...
where vmax1, vmax2, and vmax3 are the maximum rates of the corresponding stages described by the simple Michaelis equations and constants Km1, Km2, and Km3;α is the coefficient taking into account the degree of activation of the catalyst for the transformation S(2)→ S(3) by the produc...
