CO2 hydrogenation to formic acid is a high-atom-economy and environmentally friendly process. However, the short lifespan of current catalysts necessitates frequent replacement, generating significant solid waste and increasing energy costs, which severely undermines the sustainability and economic viability of the process. In this work, the stability of a Ru-based organic polymer catalyst (Ru/AP-POP-350) was dramatically improved by calcination. A 69% conversion was obtained in the hydrogenation of CO2 to formate, and stable reactivity was maintained for at least 45 cycles using Ru/AP-POP-350. The calcination changed the catalyst's structure and increased the size of the ruthenium metal clusters to achieve a good balance between catalytic reactivity and stability, which provides insights into the synthesis of highly stable catalysts for CO2 hydrogenation.

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.

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.
The hydrogenation process takes place on the surface of...
