Abstract:
Catalytic soot oxidation in automotive exhaust using non-noble metal catalysts remains an urgent challenge. Herein, the formation of surface Ni-O-Co sites via Ni solution quenching enhances the redox properties of Co-based spinel oxides, which is a strategy to promote the adsorption-activation capacity of O2 and NO, boosting NOx-assisted soot oxidation.

12.5K
Alkenes are converted to 1,2-diols or glycols through a process called dihydroxylation. It involves the addition of two hydroxyl groups across the double bond with two different stereochemical approaches, namely anti and syn. Dihydroxylation using osmium tetroxide progresses with syn stereochemistry.
