AgII-mediated electrocatalytic ambient CH4 functionalization inspired by HSAB theory.

Angew Chem Int Ed Engl 2021 Jun 9. Epub 2021 Jun 9.

University of California, Los Angeles, Department of Chemistry & Biochemistry, MSB 2505C, 607 Charles E. Young Dr. E, 90095, Los Angeles, UNITED STATES.

Developing an efficient chemical transformation pathway of ambient CH 4  functionalization is an ongoing challenge and the key resides on the discovery of new catalytic systems. The hard-soft acid-base (HSAB) theory suggests that high-valent transition metals, as soft class (b) Lewis acids based on Pearson's classification, are suitable candidates for CH 4 activation due to methyl moiety's relatively low value of chemical hardness. While most of class (b) transition metals have been studied, divalent silver (Ag II ), possibly due to its reactive nature, is the only class (b) high-valent transition metal center that is yet reported to exhibit reactivities towards CH 4  activation.

Academy of Scientific and Innovative Research (AcSIR), Ghaziabad 201002, India.

The catalytic activity of 3d-transition-metal-based electrocatalysts has exhibited considerable enhancements in electrocatalytic water splitting via pioneering modulations in the active sites. To overcome the energy loss because of the mechanic steps involved in a complex oxygen evolution reaction (OER), the electrode surface with only a few layers would be an advantage over multilayers for the ease of the electrolyte interaction and gas evolution. Here, for the first time, thin films of CoS are prepared on a carbon cloth via a pulsed laser deposition (PLD) technique via layer-by-layer deposition of Ni that tend to give Ni-CoS thin films.
