Experimentl Setion Preprtion of the iron-sed CP nnodisks CP-FeSO 4 : 5 ml FeSO 4 7H 2 O (.5 mmol) queous solution ws dded to the queous solution of 1,4,5,8-nphthlenetetrroxyli dinhydride (NTCDA) (.25 mmol) dissolved in 25 ml NOH solution (.2 M). After stirring t room temperture for 3 min, the resulting mixture ws trnsformed into Teflon-lined stinless steel seled vessel nd heted t 6 C for 24 h. Susequently, the preipitte ws isolted y entrifugtion nd wshed thoroughly with deionized wter. The preprtion of CP-FeCl 2 ws in similr method to CP-FeSO 4 with the exeption tht FeCl 2 ws used s iron slt preursor. Croniztion of the iron-sed CP nnodisks The iron-sed CP nnodisks were lined t 2 o C for 2 h nd then the lintion temperture ws rised to 9 o C or 7 o C nd kept t this temperture for 4 h under N 2 tmosphere. The heting rte during the lintions step ws 5 o C/min. The ronized produts were denoted s Fe-C-Sx nd Fe-C-Clx respetively using CP-FeSO 4 nd CP-FeCl 2 s preursors, where x refers to the lintion temperture. Preprtion of mesoporous ron mterils.2 g Fe-C-Sx or Fe-C-Clx ws dispersed in 5 ml HCl (2 M) solution nd stirred t room temperture for 5 h. And then the ron mteril ws isolted y entrifugtion nd wshed thoroughly with deionized wter. Susequently it ws dried t 1 o C for 24 h. The otined ron mterils were leled s C-Sx nd C-Clx respetively using CP-FeSO 4 nd CP-FeCl 2 s preursors, where x refers to the lintion
temperture. Chrteriztion The FT-IR spetr were reorded using KBr diss on Niolet Impt 41 spetrophotometer in the rnge 4-4 m -1. The snning eletron mirosopy (SEM) ws undertken on JEOL JSM-636 snning eletron mirosope operting t n elertion voltge of 2 kv. The trnsmission eletron mirosopy (TEM) ws performed using n FEI Teni G 2 Spirit t n elertion voltge of 12 kv. The smples were pled onto n ultrthin ron film supported on opper grid. The powder X-ry diffrtion dt were olleted on Rigku D/Mx25PC diffrtometer with Cu Kα rdition (λ=1.5418 Å) over the 2θ rnge of 5 o -7 o with sn speed of 5 o /min t room temperture. The thermogrvimetri nlysis (TGA) ws performed under N 2 tmosphere with heting rte of 5 o C/min y using NETZSCH STA-449F3 thermogrvimetri nlyzer. High resolution trnsmission eletron mirosopy (HRTEM) nd STEM imges were reorded on FEI Teni F3 mirosope with point resolution of.2 nm operted t 3 kv. The nitrogen sorption experiments were performed t 77 K on Miromeritis ASAP 22 system. Prior to the mesurement, the smples were degssed t 12 C for 6 h. Visile Rmn spetr were reorded t room temperture on Join Yvon LRAM HR 8 instrument with 532 nm exittion lser t power of round 1 mw. Eletrohemil mesurements Cyli voltmmetry experiments were rried out in three-eletrode system with n eletrohemil worksttion (CHI 7D, CH Instruments, In.). 6 M KOH queous
solution ws used s eletrolyte, mesoporous ron mterils s the working eletrode, pltinum wire s the ounter eletrode nd Ag/AgCl eletrode s the referene eletrode. The working eletrodes were prepred y mixing the ron mterils with etylene lk (1 w.t.%) nd polytetrfluoroethylene (PTFE, 5 w.t.%) nd then pressing the plstiine like mixtures onto nikel fom tht served s urrent olletor.
