Sb-doped SnO2 (ATO) support is prepared by sol-gel method in the presence of dodecylamine as template. The synthesized powder presents the highest specific surface area until now reported (216.7 m(2) g(-1)) with high electrical conductivity (0.202 S cm(-1)). The durability test accomplished by cyclic voltammetry in acid media (100 cycles between 0 and 1.7 V vs NHE) demonstrates that the ATO support maintains significantly its stability and the performance of the tested electrocatalyst compared to Vulcan XC-72. The ATO material is a promising support that can be used in several electrochemical applications where the use of carbon is not suitable. (c) 2013 Elsevier B.V. All rights reserved.
