“…7 The current-time (I-t ) chronoamperometric response of the cathode has been widely used as an effective method to test the catalytic stability and crossover or poison effects in the ORR. [123][124][125] For example, the catalytic stability of the TiN/NG and Pt/C for ORR was investigated by chronoamperometry at 0.3 V in O 2 -saturated 0.1 M KOH solutions at a rotation rate of 1600 rpm (Fig. 18b).…”

The development of low cost, durable and efficient nanocatalysts to substitute expensive and rare noble metals (e.g. Pt, Au and Pd) in overcoming the sluggish kinetic process of the oxygen reduction reaction (ORR) is essential to satisfy the demand for sustainable energy conversion and storage in the future. Graphene based transition metal oxide nanocomposites have extensively been proven to be a type of promising highly efficient and economic nanocatalyst for optimizing the ORR to solve the world-wide energy crisis. Synthesized nanocomposites exhibit synergetic advantages and avoid the respective disadvantages.In this feature article, we concentrate on the recent leading works of different categories of introduced transition metal oxides on graphene: from the commonly-used classes (FeO x , MnO x , and CoO x ) to some rare and heat-studied issues (TiO x , NiCoO x and Co-MnO x ). Moreover, the morphologies of the supported oxides on graphene with various dimensional nanostructures, such as one dimensional nanocrystals, two dimensional nanosheets/nanoplates and some special multidimensional frameworks are further reviewed.The strategies used to synthesize and characterize these well-designed nanocomposites and their superior properties for the ORR compared to the traditional catalysts are carefully summarized. This work aims to highlight the meaning of the multiphase establishment of graphene-based transition metal oxide nanocomposites and its structural-dependent ORR performance and mechanisms.

Fuel cells have long been considered as highly efficient devices for energy conversion which transform chemical energy directly into electricity, without any venomous pollutants emitted into ambient environment. In recent years, graphene-polymer nanocomposites have attracted intense interest as functional components in fuel cells. This chapter focuses on the potential applications of graphene-polymer composites in fuel cells. Recent advancement in the synthesis of graphene, polymer, graphene-polymer composites will be presented. Then, latest explorations of graphene-polymer composites applied as membranes, anode and cathode materials will be summarized. Furthermore, the vital roles of graphene-polymer to support noble metal catalysts will be illustrated. Finally, prospects of graphene-polymer composites for fuel cells will be outlined for further development.
