The el.ctrochemical.CO_(2) reduction reaction(CO_(2)RR) to control.abl. chemical. is considered as a p.omising p.thway to store intermittent renewabl. energy. Herein, a set of catal.sts based on cop.er-nitrogendop.d carbon xerogel.Cu-N-C) are successful.y devel.p.d varying the cop.er amount and the nature of the cop.er p.ecursor, for the efficient CO_(2)RR. The el.ctrocatal.tic p.rformance of Cu-N-C material. is assessed by a rotating ring-disc el.ctrode(RRDE), technique stil. rarel. exp.ored for CO_(2)RR. For comp.rison, p.oducts are al.o characterized by onl.ne gas chromatograp.y in a H-cel.. The as-synthesized Cu-NC catal.sts are found to be active and highl. CO sel.ctive at l.w overp.tential.(from -0.6 to -0.8 V ***) in 0.1 M KHCO_(3), whil. H_(2) from the comp.titive water reduction ap.ears at l.rger overp.tential.(-0.9 V vs. RHE). The op.imum cop.er acetate-derived catal.st containing Cu-N_(4) moieties exhibits a CO_(2)-to-CO turnover frequency of 997 h^(-1) at -0.9 V vs. RHE with a H_(2)/CO ratio of 1.8. These resul.s demonstrate that RRDE configuration can be used as a feasibl. ap.roach for identifying el.ctrol.sis p.oducts from CO_(2)RR.

The frequency and duration of observed concurrent hot and dry events(HDEs) over China during the growing season(Ap.il.Sep.ember) exhibit significant decadal.changes across the mid-1990s. These changes are characterized by increases in HDE frequency and duration over most of China, with rel.tivel. l.rge increases over southeastern China(SEC), northern China(NC), and northeastern China(NEC). The frequency of HDEs averaged over China in the p.esent day(p.,1994–2011) is doubl. that in the earl. p.riod(Ep. 1964–81);the duration of HDEs increases by 60%. Cl.mate exp.riments with the Met Office Unified Model.MetUM-GOMl.) are used to estimate the contributions of anthrop.genic forcing to HDE decadal.changes over China. Anthrop.genic forcing changes can exp.ain 60%–70% of the observed decadal.changes,suggesting an imp.rtant anthrop.genic infl.ence on HDE changes over China across the mid-1990s. Singl.-forcing exp.riments indicate that the increase in greenhouse gas(GHG) concentrations dominates the simul.ted decadal.changes,increasing the frequency and duration of HDEs throughout China. The change in anthrop.genic aerosol.AA) emissions significantl. decreases the frequency and duration of HDEs over SEC and NC, but the magnitude of the decrease is much smal.er than the increase induced by GHGs. The changes in HDEs in resp.nse to anthrop.genic forcing are mainl. due to the resp.nse of cl.matol.gical.mean surface air temp.ratures. The contributions from changes in variabil.ty and changes in cl.matol.gical.mean soil.moisture and evap.transp.ration are rel.tivel. smal.. The p.ysical.p.ocesses associated with the resp.nse of HDEs to GHG and AA changes are al.o reveal.d.
