Nitrogen-doped carbons with hierarchical porosity via chemical blowing towards long-lived metal-free catalysts for acetylene hydrochlorination

Kaiser, Selina K. ; Song, Kyung Seob ; Mitchell, Sharon ; Coskun, Ali ; Pérez‐Ramírez, Javier

Porous nitrogen‐doped carbons (NCs) are sustainable alternatives to the toxic mercury‐based acetylene hydrochlorination catalysts applied in the manufacture of polyvinyl chloride. However, the application of NCs as metal‐free catalysts is hampered by their insufficient durability under industrially relevant process conditions. In particular, pore blockage leads to accelerated...

Heptacoordinate Co(II) catalyst for light-driven hydrogen production in fully aqueous medium

Lucarini, Fiorella ; Ruggi, Albert

In: CHIMIA International Journal for Chemistry, 2018, vol. 72, no. 4, p. 203–206

Photocatalytic hydrogen production is an appealing way to store solar energy as chemical fuel. The most studied molecular catalysts for H2 production are based on earth-abundant metals such as Ni, Co and Fe. Efforts have been recently focused on the design of Co complexes with distorted octahedral geometries induced by tetra- or pentapyridyl ligands. We synthesized a new Co(II) complex based...
