Abstract

Small and narrowly distributed Cu nanoparticles, supported on SiO ₂ decorated with isolated Ti ^IV sites, prepared through surface organometallic chemistry, showed significantly improved CO ₂ hydrogenation activity and CH ₃ OH selectivity compared to the corresponding Cu nanoparticles supported on SiO ₂ . These isolated Lewis acid Ti ^IV sites, evidenced by UV/Vis spectroscopy, are proposed to stabilize surface intermediates at the interface between Cu nanoparticles and the support.
