Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 19692-45-6, Name is 1-(tert-Butyl)-4-(chloromethyl)benzene, molecular formula is , belongs to chlorides-buliding-blocks compound. In a document, author is Shamraiz, Umair, Category: chlorides-buliding-blocks.
Retention of anions in cobalt hydroxide with Ni substitution to emphasize the role of anions and cations for high current density in oxygen evolution reactions
Herein, we report the fabrication of remarkably fine nickel-substituted alpha-Co(OH)(2) sheets using an ingenious co-precipitation method at a lower pH value. An alpha-CoNiOOH sheet retains the parent alpha-Co(OH)(2) structure consisting of both tetrahedral (Td) and octahedral (Oh) sites with the retention of interlayer chloride ions, which is in contrast to the previous reports. The as-synthesized alpha-CoNiOOH sheet exhibits excellent oxygen evolution reactions (OERs) and produces a current of 10 mA cm(-2) at an overpotential of merely 190 mV in an alkaline environment. Moreover, the alpha-CoNiOOH sheet attains an exceptionally high current density of 100 mA cm(-2) at a low overpotential of only 270 mV. Additionally, this electrocatalyst possesses a 33 mV dec(-1) Tafel slope with higher values of TOF (11 s(-1)) and double-layer capacitance (7.76 mF cm(-2)). This enhancement is attributed partially to the substitution of Ni during the conversion of alpha-Co(OH)(2) to alpha-CoNiOOH and partially to the exceptionally thin sheets allowing potential octahedral sites for improved oxygen evolution reactions.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 19692-45-6, in my other articles.
