Aerom.gn.tic data over the m.m.e Basin.have been.processed.

The electrochem.cal CO_(2) reduction.reaction.CO_(2)RR) to con.rollable chem.cals is con.idered as a prom.sin. pathway to store in.erm.tten. ren.wable en.rgy. Herein. a set of catalysts based on.copper-n.trogen.oped carbon.xerogel(Cu-n.C) are successfully developed varyin. the copper am.un. an. the n.ture of the copper precursor, for the efficien. CO_(2)RR. The electrocatalytic perform.n.e of Cu-n.C m.terials is assessed by a rotatin. rin.-disc electrode(RRDE), techn.que still rarely explored for CO_(2)RR. For com.arison. products are also characterized by on.in. gas chrom.tography in.a H-cell. The as-syn.hesized Cu-n. catalysts are foun. to be active an. highly CO selective at low overpoten.ials(from.-0.6 to -0.8 V ***) in.0.1 m.KHCO_(3), while H_(2) from.the com.etitive water reduction.appears at larger overpoten.ials(-0.9 V vs. RHE). The optim.m.copper acetate-derived catalyst con.ainin. Cu-n.(4) m.ieties exhibits a CO_(2)-to-CO turn.ver frequen.y of 997 h^(-1) at -0.9 V vs. RHE with a H_(2)/CO ratio of 1.8. These results dem.n.trate that RRDE con.iguration.can.be used as a feasible approach for iden.ifyin. electrolysis products from.CO_(2)RR.
