Figure 6. Ni-loading-dependent methane decomposition performance and carbon productivity of xNi-LCCM catalysts at 750 °C. (A) Methane conversion as a function of time on stream over xNi-LCCM catalysts; (B) Catalyst-mass-normalized carbon productivity; (C) Ni-normalized carbon productivity. The experiments were conducted in a rotary reactor at 750 °C and 1 rpm for 8 h with a space velocity of
