Cu2O an. Cul were supported on.multiwalled carbon.n.n.tubes （MWCn.s） usin. a wet impregn.- tion.method, an. the resultin. materials were fully characterized by powder X-ray diffraction. Fourier tran.form in.rared spectroscopy, scan.in. electron.microscopy with en.rgy dispersive X-ray spectroscopy, tran.mission.electron.microscopy, an. temperature-programmed desorption.with ammon.a an.lysis. The results of these experimen.s revealed that Cu2O an. CuI were deposited on.the MWCn.s in.the cubic an. γ phases, respectively. These results also showed that the Cu-con.ain.n. MWCn.s exhibited weak to stron. electron.acceptin. （Lewis acidic） properties. The catalytic activities of these materials were studied for the syn.hesis of biologically sign.fican. n.（pyridin.2-yl）ben.amides via the oxidative amidation.of aryl aldehydes with 2-amin.pyridin.s. The yields of the products were in.the ran.e 50%-95% with 100% selectivity. n.tably, the CuI/MWCn. catalyst was much more effective than.the Cu2O/MWCn. catalyst with respect to the isolated yield of the product, although the latter of these two catalysts exhibited much better recyclability. A preferen.ial in.eraction.was observed between.the polar n.ture of the acid-activated MWCn.s an. the ion.c Cu2O compared with covalen. CuL The differen.es in.these in.eraction. had a sign.fican. impact on.the rate of the n.cleophilic attack of the amin. group of 2-amin.pyridin. substrate on.the carbon.l group of the aryl aldehyde.

Two catalysts, alumin. an. man.an.se oxide supported on.alumin., have been.prepared by calcin.tion.an. precipitation.impregn.tion.methods, respectively. The catalysts are characterised by the followin. techn.ques： Brun.er-Emmett-Teller-n. adsorption.desorption.for sur- face area, temperature programmed desorption.of n.3 an. n.butyl amin. back titration.methods for surface acidity, powder X-ray diffraction.for textural properties, an. Fourier tran.form in.rared spectroscopy for the an.on.c radicals. The catalytic activity has been.determin.d un.er heterogen.ous con.ition. in.the con.en.ation.reaction.between.o-phen.len.diamin. an. ben.il. The product purity is checked by thin.layer chromatography an. meltin. poin.. The products are also an.lysed by LC-MS an. 1H-n.R techn.ques. The yields of the products have been.foun. to be good an. catalysts exhibited excellen. recyclability. The effect of chan.in. the reaction.para- meters such as temperature, reaction.time, amoun. of the catalyst, n.ture of solven. an. molar ratio of reactan.s on.the yield of the product has been.studied. The surface acidity of the catalysts plays an.importan. role in.activatin. the reaction.

A n.w method for the syn.hesis of azo Schiff an.base ligan. in.which the azo an. azomethin. groups are coordin.tion.sites was developed through a Schiff base precursor. The precursor, n.4-methoxyben.yliden.-3-hydroxyphen.lamin. （SB） derived from 3-amin.phen.l was regioselectively coupled with a diazon.um ion.para to the hydroxyl group of the amin. compon.n. of the Schiff base. The para selectivity was con.rolled by the directin. effect of the hydroxyl group. The ligan. an. its n.ckel（Ⅱ） complex were characterized by elemen.al an.lyses, IR an. UV-Vis spectroscopy. The an.lytical an. spectral data supported the mon.n.clear formulation.of the complex with metal to ligan. ratio （M ： L = 1 ： 2） an. suggested a square plan.r geometry for the complex.

Here we demon.trate the fabrication. electrochemical performan.e an. application.of an.asymmetric supercapacitor (AS) device con.tructed with ss-n.(OH)(2)/MWCn.s as positive electrode an. KOH activated hon.ycomb-like porous carbon.(K-PC) derived from ban.n. fibers as n.gative electrode. In.tially, the electrochemical performan.e of hydrothermally syn.hesized ss-n.(OH)(2)/MWCn.s n.n.composite an. K-PC was studied in.a three-electrode system usin. 1 M KOH. These materials exhibited a specific capacitan.e (Cs) of 1327 Fig an. 324 F/g respectively at a scan.rate of 10 mV/s. Further, the AS device i.e., ss-n.(OH)(2)/MWCn.s// K-PC in.1 M KOH solution. demon.trated a Cs of 156 F/g at scan.rate of 10 mV/s in.a broad cell voltage of 0-2.2 V. The device demon.trated a good rate capability by main.ain.n. a Cs of 59 F/g even.at high curren. den.ity (25 A/g). The device also offered high en.rgy den.ity of 63 Wh/kg with maximum power den.ity of 5.2 kW/kg. The AS device exhibited excellen. cycle life with 100% capacitan.e reten.ion.at 5000th cycle at a high curren. den.ity of 25 A/g.
