“…Many porous transition metal oxides, such as CuO, Cu 2 O, Mn 2 O 3 , Mn 3 O 4 , Co 3 O 4 , and ZnO among others, have been derived through thermolysis under controlled atmospheres.

3268 wileyonlinelibrary.com inorganic nodes in MOFs can be intrinsic active sites for catalysis, e.g., copperbased MOFs have been demonstrated as an excellent solid Lewis acid catalyst for a few reactions; [ 4,7 ] (ii) extrinsic functional species (e.g., nanoparticles) can be introduced to MOFs structure, either on the external surfaces or inside the bulks or shells of MOFs. Various catalytic nanoparticles have been successfully incorporated into different MOFs matrices, including Au, Ag, Pt, Cu, or their combination etc.; [8][9][10] and (iii) MOFs also serve as solid precursors for metal or metaloxide catalysts due to their high metal density within the frameworks and easy transformation. Many porous transition metal oxides, such as CuO, Cu 2 O, Mn 2 O 3 , Mn 3 O 4 , Co 3 O 4 , and ZnO among others, have been derived through thermolysis under controlled atmospheres.

[ 17 ] Although a fi ne control over the size and size-distribution of MOFs has been realized, e.g., in the range of 100 nm to several micrometers, [ 18 ] fashioning MOFs into desired shapes for specifi c applications remain to be challenging. Nevertheless, several attempts to the architectural control of MOFs shapes have recently appeared in the literature, ranging from 1D, 2D to 3D nanostructures. [ 19,20 ] For example, nanosheets of MOFs as molecular sieving membranes for gas separation have been made in two recent reports, [ 21,22 ] which achieved much higher separation selectivity than MOFs in other

a b s t r a c tPorous carbon supported copper composite (Cu/Cu 2 O/C) was synthesized with a facile, low cost and novel method and used as non-noble-metal catalyst for reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) by NaBH 4 . In the synthetic strategy, metal organic framework Cu 3 (BTC) 2 (also denoted as HKUST-1) was used as both sacrificial template and copper precursor, and phenol formaldehyde resin as carbon precursor. The catalytic Cu/Cu 2 O nanoparticles (Cu/Cu 2 O NPs) about 40 nm-indiameter distributed uniformly both on the internal and external surface of the porous carbon flakes, and took up 33.38e37.56 wt% of the Cu/Cu 2 O/C composite. Compared with noble metal catalysts, the prepared composite showed comparable high catalytic activity, which was mainly due to their porous structure facilitating diffusion of reactants and products, and the high dispersion of accessible catalytic Cu/Cu 2 O NPs on porous carbon. Moreover, the synthesized catalyst can be reused for at least five cycles due to its good stability. These results confirmed that the as-prepared Cu/Cu 2 O/C is promising candidate to replace noble metal for catalytic application.

“…8 To date, porous copper (II) oxide micro-/nanospheres, nanowires, nanosheets, nanobelts, nanospindles, microrods, hollow octahedra and hexapod nanostructures have been prepared and displayed outstanding properties. [9][10][11][12][13][14][15][16] In the authors' previous work, porous copper (II) oxide microspheres were prepared by the solvothermal method, which showed a good response sensitivity and low detection concentration for ethanol. 8 Porous copper (II) oxide hollow octahedra were synthesized by using metal organic frameworks (MOFs) as templates.…”

“…These displayed remarkable advances in the electrochemical performance for lithium-ion battery anode materials. 15 Porous copper (II) oxide nanobelts-on-single-walled carbon nanotube composites were prepared by Zhang et al, 17 which showed high specific capacitance and more stable cycling performance. Despite these successes, their preparation methods required a surfactant, template or solvent which can attach to the surface and had a negative performance impact.…”

Porous manganese (Mn)-doped copper (II) oxide (CuO) microplates were synthesized by a facile hydrothermal method. The as-prepared samples were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Brunauer-Emmett-Teller N 2 adsorption-desorption analysis and Fourier transform infrared spectroscopy. It is shown that the morphologies of samples can be transformed from hierarchical porous microspheres to microplates by doping with manganese ions. The manganese-doped copper (II) oxide (10%) has a wide pore size distribution from micropore to macropore, and its surface area is 16·82 m 2 /g, which is 2·4 times that of copper (II) oxide microspheres (6·92 m 2 /g). It shows excellent adsorption properties for potassium ethyl xanthate. The saturated adsorption capacity of porous manganese-doped copper (II) oxide (10%) microplates for potassium ethyl xanthate is 5219 mg/g, which is 6·4 times that of copper (II) oxide microspheres (813 mg/g). The excellent adsorption property is mainly attributed to the intrinsic structure and the large specific surface area. This approach is expected to be extended to the preparation of other porous materials.Langmuir constrants m mass of the sample (g) q e adsorption capacity (mg/g) V volume of solution
