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.

“…In order to overcome this problem, MoO 2 with different morphology have been synthesized, such as MoO 2 nanospheres, [13] ordered mesoporous MoO 2 , [3] tremella-like MoO 2 , [11] MoO 2 nanoparticles, [12] MoO 2 nanofibers [14] and ultrafine MoO 2 nanosheets. [15] Besides, carbonaceous materials such as amorphous carbon, [13,16] carbon nanotubes (CNT) [17,18] and graphene [19][20][21] have been used to incorporate with MoO 2 . Among these carbon materials, the amorhous carbon with good conductivity can improve the conductivity of MoO 2 .…”

“…The other strategy, forming a carbon composite, has demonstrated its ability to improve the performance of MoO 2 electrode [7,[17][18][19][20]. Carbon acts not only to prevent exfoliation of the active material, but also to improve the conductivity of MoO 2 , resulting in the enhancement of charge-discharge reversibility and cycling performance.…”

MoO2/Mo2C/C spheres have been synthesized through hydrothermal and calcination processes. MoO2 is well known for its high theoretical capacity of 838 mAh g-1, but undergoes capacity fading during Li+ insertion/extraction processes. Mo2C has high specific conductance (1.02 x 102 S cm-1) that can provide better electronic conductivity. Carbon is popular for its ability to accommodate the volume variation during charge/discharge. By taking advantage of the combination of Mo2C and C, these MoO2/Mo2C/C spheres demonstrate not only high cycling performance, but also good rate capability when they are used as anode materials for lithium ion batteries. After 100 cycles at 100 mA g-1, the discharge capacities of the MoO2/ Mo2C/C spheres remain at 800 mAh g-1, suggesting that MoO2/Mo2C/C spheres are promising candidates as anode material for lithium ion batteries.
