Abstract:
Tandem CO2 reduction with carbonylation reactions represents a promising approach to convert greenhouse gases into valuable chemicals. Herein, we propose a universal "N/O mixed pre-coordination pyrolysis" strategy to construct vacancy-defect single atom catalysts (Ni1-, Mn1-, Fe1-, Co1-, and Cu1-NC) with M-N3 coordination microenvironment. This vacancy-defect endows Ni1-NC with excellent performance for CO2 electroreduction, achieving a CO faradaic efficiency exceeding 90% across a wide range of current densities up to 300 mA cm-2. The generated CO was directly fed to carbonylation reactions, producing organic chemicals with yields of up to 91.7% and leading to produce 1.13 g of benzophenone in a single run. For the first time, the membrane separation CO2 system was integrated with tandem catalytic system, enabling direct utilization of flue gas for benzophenone synthesis with a 76.6% yield. This work offers a sustainable, eco-friendly method for CO2 separation and utilization by feeding industrial waste gas to carbonylation reactions.

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
