We study nucleosynthesis in low accretion rate hot advective flows around black holes. We find that matter is generally photo-dissociated into protons and neutrons inside the disk. These neutrons stay around black holes for longer time because they are not coupled to magnetic fields while the protons accrete into the hole. We find the nature of the resulting neutron disks and estimate the rate at which these disks contaminate the surroundings.
