Here, we investigated how semiconductor nanoparticles (NPs) with sizes ranging between 2.3\u20133.5\u2005nm form nano\u2010biohybrids with the nitrogenase enzyme and enable its photoinduced biocatalytic activity. We examined two homogenously synthesized quantum dots (QDs), CdS, CdSe, and two nitrogenase variants, the wild\u2010type and a cysteine\u2010mutated. We show that the cysteine\u2010mutated variant does not enhance the hydrogen generation amounts, as compared with the wild type. Nevertheless, we show that the 2.3\u2005nm\u2010sized CdSe NPs facilitate an eightfold increase compared with larger CdSe NPs. The obtained results were investigated using electrochemical techniques, transmission electron microscopy, and further confirmed by time\u2010resolved spectroscopic measurements, which allow us to determine the electron tranfer rate constant (<jats:italic>k<\/jats:italic><jats:sub>ET<\/jats:sub>) of the different
