Nanoporous TiO2 having enhanced surface area was synthesized by sol–gel method. An “environmental friendly” method for production of furfuryl
alcohol was presented by electrocatalytic reduction of furfural to furfuryl alcohol in ionic liquid medium at the surface
of nanoporous TiO2 film electrode. The heterogeneous catalytic redox behaviour of a nanoporous TiO2 film electrode surface was investigated by cyclic voltammetry (CV). It was found that the catalytic reduction of furfural
by Ti(IV)/Ti(III) redox system on the nanoporous TiO2 film surface. The electrode reaction mechanism is called catalytic (EC′) mechanism, current density can reach 38 mA/cm2 and yielding an overall conversion efficiency of 61.7%. 相似文献

电合成系列锌配合物及纳米ZnO的制备 总被引:4,自引:0,他引:4
采用锌金属为“牺牲”阳极,首次在无隔膜电解槽中,电化学一步法制备了纳 米ZnO前驱体锌配合物Zn(OEt)_2, Zn(OBu)_2, Zn(acac)_2, Zn(OEt)_2(acac)_2, Zn(OBu)_2(acac)_2(acac为乙酰丙酮基),产物通过红外光谱(FTIR)、拉曼光谱和 核磁共振进行表征。同时采用含Zn(OEt)_2(acac)_2的电解液直接水解制备纳米 ZnO粉体,纳米ZnO通过拉曼光谱、X射线粉末衍射(XRD)和透射电子显微镜(TEM) 进行表征。实验表明电解时防止阳极钝化,控制温度在50~60 ℃之间,采用有机 胺溴化物为导电盐,可以提高电合成效率;电解合成Zn(acac)_2, Zn(OEt)_2 (acac)_2, Zn(OBu)_2(acac)_2的电流效率比Zn(OEt)_2, Zn(OBu)_2高,其中Zn (OEt)_2(acac)_2适宜作为溶胶-凝胶法制备纳米ZnO的原料,制备得到的纳米ZnO经 600 ℃煅烧后呈球形单分散结构,平均粒径在5~10nm左右。 相似文献
