Effect of the size and distribution of supported Ru nanoparticles on their activity in ammonia synthesis under mild reaction conditions

•A larger size of Ru nanoparticles leads to a higher (TOF).•Heterogeneous distribution of the size of Ru nanoparticles favors higher TOF.•Homogeneous distribution of size of Ru nanoparticles leads to lower TOF. Ru/γ-Al2O3 catalysts were prepared using three different methods: wet impregnation, collo...
