“…The turnover frequency (TOF) based on exposed Rh decreased with increasing rhodium dispersions [23]. It has been shown that lanthana can substantially modify the chemical behavior of M/SiO 2 systems [24] and their activity for several reactions [8]. The role of La 2 O 3 as promoter on Rh-silica solids in the syngas production from CO 2 and CH 4 was explored by Gronchi et al [25] using 5% La 2 O 3 -SiO 2 obtained by impregnation.…”
