Hydride Transfer Limits Hydrogen Evolution Efficiency With Zn Porphyrin Photocatalysts [PDF]
Chem Asian JThe mechanism of photocatalytic hydrogen evolution catalyzed by a Zn‐based metalloporphyrin, using water and a cheap sacrificial donor, is studied computationally. The efficiency of hydrogen formation is limited by the competition with hydrogenation of the porphyrin, which leads to a reduced macrocycle.

FEBS Letters, 1994 Monoclonal antibodies against Pd‐coproporphyrin I have been obtained. The antibody specificity for free as well as for conjugated Pd‐coproporphyrin I is characterized. Affinity constants are estimated for 3 monoclonal antibodies effectively interacting with free Pd‐coproporphyrin I.
