Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 73-22-3, Name is H-Trp-OH, molecular formula is C11H12N2O2, belongs to catalyst-ligand compound, is a common compound. In a patnet, author is Zhang, Yafeng, once mentioned the new application about 73-22-3, COA of Formula: C11H12N2O2.
Tunable strain drives the activity enhancement for oxygen reduction reaction on Pd@Pt core-shell electrocatalysts
An effective way to tune the surface reactivity of catalysts in electrocatalysis is by engineering their surface strain. Traditionally, activity enhancement for the oxygen reduction reaction (ORR) can be attributed to both strain and ligand effects for Pt-based catalysts. Herein, we successfully use variable shell thickness to tune surface strain and thus tailor the ORR catalytic activity of core-shell electrocatalysts in acid media. Increasing reaction temperature from 140 degrees C to 180 degrees C in a typical one-pot solvothermal method increases the thickness of Pt shells from 3.0 to 14.0 monolayers, by increments of 3 monolayers per 10 degrees C (3 ML/10 degrees C). The surface strains of -1.85% to -0.18% are achieved with increasing Pt shell thickness. Relative to a commercial Pt/C catalyst, the optimum mass activity of a [email protected]/C catalyst (0.95 A mg(Pt)(-1)) is found to be greater by a factor of 5.3. The theoretical study on the strain-activity relation reveals that [email protected]/C possesses 1.85% of surface compression, and the optimum oxygen binding energy (0.15 eV). The Pd@Pt-nL/C catalysts show desirable stability compared with commercial Pt/C catalyst after 8000 cycles, especially [email protected]/C, with 97.7% of initial mass activity.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 73-22-3. The above is the message from the blog manager. COA of Formula: C11H12N2O2.
