Carbon-supported Ir 3 Sn/C and Ir/C catalysts were simply prepared with NaBH 4 as a reducing agent under the protection of ethylene glycol at room temperature. TEM and X-ray diffraction (XRD) data showed that the catalysts with small particle size exhibited the typical characteristic of a crystalline Ir fcc structure. Their electrocatalytic activities in comparison with Pt/C and Pt...
Organic silica with thiol group/Nafion ® composite membranes were prepared by the casting method using various additives including HS(CH 2 ) 3 CH 3 Si(OCH 3 ) 2 (SH–), tetraethyl orthosilicate (TEOS) and HS(CH 2 ) 3 CH 3 Si(OCH 3 ) 2 -TEOS (HS-TEOS) in Nafion solutions. All composite membranes had an adulterated content...
