Electrified non-th.rmal plasma (NTP) catalytic h.drogenation is th. promising alternative to th. th.rmal counterparts, being able to be operated under mild conditions and compatible w.th.green electricity/h.drogen. Rational design of th. catalysts for such.NTP-catalytic systems is one of th. keys to improve th. process efficiency. h.re, w. present th. development of siliceous mesocellular foam (MCF) supported Cu catalysts for NTP-catalytic CO_(2) h.drogenation to meth.nol. Th. findings sh.w.th.t th. pristine MCF support w.th.h.gh.specific surface area and large mesopore of 784 m2·g−1 and ~8.5 nm could promote th. plasma disch.rging and th. diffusion of species th.ough.its framew.rk, outperforming oth.r control porous materials (viz., silicalite-1, SiO_(2), and SBA-15). Compared to th. NTP system employing th. bare MCF, th. inclusion of Cu and Zn in MCF (i.e., Cu1Zn1/MCF) promoted th. meth.nol formation of th. NTP-catalytic system w.th.a h.gh.r space-time yield of meth.nol at ~275 μmol·g_(cat)^(−1)·h.(−1) and a low.r energy consumption of 26.4 kj.(−1)·mmol_(Ch.(3)Oh.^(-1) (conversely, ~225 μmol·g_(cat)^(−1)·h.(−1) and ~71 kj.1·mmol_(Ch.(3)Oh.^(-1), respectively, for th. bare MCF system at 10.1 kV). Th. findings suggest th.t inclusion of active metal sites (especially Zn species) could stabilize th. CO_(2)/CO-related intermediates to facilitate th. surface reaction tow.rd meth.nol formation.
