The purpose of this study was to investigate the effect of different conditions on the microsphere morphology of MnMoO4 nanofiber and the performance of MnMoO4 nanocatalyst in the reaction of γ-amino acids. The obtained results proved that, the effect of different mechanical pressures, time of hydrothermal processing and calcination on the amount of fibers and morphology of MnMoO4 product is related. In addition, the reaction can be catalyzed through the photoredox catalyst and adapt to different amines and styrenes. Such a technique presents hugely functionalized γ-amino acids in adequate performances with utmost regioselection. The synthesis described here is the first instance of a γ-amino acid from CO2 that has been visible-light-induced. The reaction in the presence of 20 mg of MnMoO4 had a yield of 94%. Also, the reaction was not performed without light and catalyst. The catalyst was recycled 5 times and its performance was slightly reduced. It has many advantages, including no environmental damage, the least amount of catalyst due to its fiber structure, cost-effectiveness, operational simplicity, quick reaction times, high atom economy and perfect yields.
