A density functional theory-based study was performed to investigate the stability of single-atom catalysts (SACs) over a series of O-terminated MXenes with the stoichiometry of M2CO2. Accordingly, we selected the first-row transition metals as adato

[eng] Transition metal carbides (TMCs) have acquired a wide potential as a green chemistry catalysts. Their relatively high abundance and their catalytic performance makes them great candidates to replace scarce and pollutant catalysts as Pt, as well

Palladium-based metal-organic frameworks (Pd-MOFs) are an emerging class of heterogeneous catalysts extremely challenging to achieve due to the facile leaching of palladium and its tendency to be reduced. Herein, Pd(II) was successfully incorporated

Cobalt demand is increasing due to its key role in the transition to clean energies. Although the main Co ores are the sediment-hosted stratiform copper deposits of the Democratic Republic of the Congo, Co is also a by-product of Ni–Co laterite dep

We describe a novel transition metal-free method for the synthesis of N-difluoromethylated pyridines and 4-pyridones/quinolones by using readily available ethyl bromodifluoroacetate as a fluorine source. The formation of N-difluoromethylated pyridine
