One-pot wet-chemical co-reduction synthesis of bimetallic gold–platinum nanochains supported on reduced graphene oxide with enhanced electrocatalytic activity Original Research Article Journal of Power Sources, Volume 287, 1 August 2015, Pages 363-369 De-Jun Chen, Qian-Li Zhang, Jin-Xia Feng, Ke-Jian Ju, Ai-Jun Wang, Jie Wei, Jiu-Ju Feng
Graphical abstractA simple, rapid, and facile one-pot wet-chemical co-reduction method is developed for the synthesis of bimetallic Au–Pt nanochains networks supported on reduced graphene oxide (RGO). The as-prepared nanocomposites show highly electrocatalytic activity and stability toward methanol and EG oxidation.

Graphical abstractA graphene oxide (GO) membrane was prepared on ceramic disk via a vacuum-assisted filter method. The GO membrane with a typical 2D structure exhibits selective water permeation due to the hydrophilic groups on GO sheets. The ceramic supported GO membrane with submicron thickness and enhanced mechanical strength was applied for the pervaporation dehydration of butanol. The GO membrane showed a high permeate of 3.1 kg·m-2·h-1 and a separation factor of 230 at the conditions with a PV temperature of 50 oC and a feed water content of 10%(by mass). After running for 1800 min, the GO membrane still showed a good stability. Such GO membranes are potential candidates for the dehydration of butanol.
