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.

“…It has been shown in previous work that MOFCs can inherit some of the functionalities from their parent MOFs during pyrolysis . For CO 2 capture, an enhancement of the CO 2 adsorption affinity can be expected by incorporating pyridinic‐N groups on the surface of porous carbon.…”

The development of functional porous carbon with high CO2 /N2 selectivity is of great importance for CO2 capture. In this paper, a type of porous carbon with doped pyridinic sites (termed MOFC) was prepared from the carbonization of a pyridyl-ligand based MOF. Four MOFCs derived from different carbonizing temperatures were prepared. Structural studies revealed high contents of pyridinic-N groups and nearly the same pore-size distributions for these MOFCs. Gas-sorption studies revealed outstanding CO2 uptake at low pressures and room temperature. Owing to the high content of pyridinic-N groups, the CO2 /N2 selectivity on these MOFCs exhibits values of about 40-50, which are among the top values in carbon materials. Further correlation studies demonstrated that the CO2 /N2 selectivities show a positive linear relationship with the surface density of pyridinic-N groups, thus validating the synergistic effect of the doped pyridinic-N groups on CO2 adsorption selectivity.

A coordination polymer constructed from the ligand 2,2Јbipyridine-5,5Ј-carboxylate (Bpydc) with hybrid functional groups and the co-ligand SO 4 2was synthesized and structurally characterized by single-crystal X-ray diffraction. It shows an intriguing structure of parallel infinite Mn-SO 4 double chains resulting from the coordination of SO 4 2groups to central Mn II atoms. Further linkage of the Bpydc ligands with the Mn-SO 4 double chains gave rise to a three-dimensional pillar-layer framework, in which the Mn-SO 4 double chains act as pillars and the Bpydc ligands form the layers.
