“…which is generally consistent with the gradually increased specific surface areas of these 21 composites. Therefore, sample ZnO/C-S-L derived from steam carbonization for longer time shows the highest CO 2 uptake at 1 bar amongst these composites.…”

“…Due to the inorganicorganic crystal structure of the parental MOFs, the generated metal or metal oxide can be remained homogeneously within the nanoporous carbon matrix. [21] To date, only a few reports have adopted such a thermal treatment of MOFs route for the fabrication of composites. Das et al reported a generalized strategy for the synthesis of crystalline metal oxide nanoparticles embedded in a carbon matrix by a controlled thermolysis of MOFs.…”

“…[17,18] However, the components in these porous carbon-metal oxide composites usually cannot achieve homogeneous dispersion since they were frequently prepared by mechanical or physical mixing the metal oxides with the porous carbon materials. More recently, metal 4 organic frameworks (MOFs) (including Zeolitic Imidazolate Frameworks (ZIFs)), a new class of inorganic-organic crystalline nanoporous materials that assembled from metal ions coordinated to rigid organic ligands, [19,20] have emerged as promising precursors or sacrificial templates for the preparation of porous carbon based materials, [21,22] due to their tuneable structures, vast functionalities and fascinating properties. The preparation procedure is simple, and porous carbon-based materials can be produced by the direct carbonization of MOFs in an inert atmosphere, without any additional carbon precursors.…”

Advanced functional composite of ZnO nanoparticles embedded in N-doped nanoporous carbons has been synthesized by a simple one-step carbonization of zeolitic imidazolate framework-8 under a water stream atmosphere. A variety of characterization techniques show that the introduction of water steam during the carbonization process holds the key to obtain the fine and homogeneously dispersed ZnO nanoparticles within the functionalised nanoporous carbon matrix. Possessing a higher specific surface area, a larger pore volume and abundant oxygen-containing hydrophilic functional groups, the resulting composite exhibits a stronger interaction with CO 2 and is more efficient to promote the photocatalytic degradation-adsorption of methylene blue under visible light than the composite obtained without steam treatment. As a result, the steam derived composite exhibits increased CO 2 uptake capacity and excellent methylene blue molecules removal from water. Using different metal-organic frameworks as precursors, this new, simple and green method can be further expanded to generate various new homogeneous dispersed functional metal oxide/porous carbon composites with high efficient in relevant applications.

Biomass materials have received attention for energy storagebecaused of the advantage of low-cost, easy-to-prepare, and eco-friendliness. Three-dimensional carbon materialswith abundant pore structure gradually becomeresearch hotspot in high-performance energy storage. In this study, an easy-to-prepare, green, light and elastic activated carbon was present using the biomass Juncus effusus (JCE) via high-temperature pyrolysis, followed by activation in air. Compared with previously reported bio-carbons, the proposed air-activated bio-carbon contributes in the fabrication of pores to preserve the interconnected, reticular and tubular structure. Moreover, the interconnected porous material also inherits the excellent tenacity of the original JCE such as the material can be bended to below 90 o under an external force while maintaining structural integrity. The activated porous carbon material exhibits an enhanced electric double-layer capacitance (~210 F g -1 at 1 A g -1 ), with capacitance retention of ~78.62% at 10 A g -1 . The interconnected porous carbon microtubes electrode as a double-layer symmetric capacitor exhibits considerable capacitance retention (84%) after 2000 cycles at 1 A g -1 . The improved energy storage performance was proposed to be attributed to the shortened ionic diffusion distance and sufficient contact between the interface of the carbon electrode and electrolyte, which is resulted from the elastic, undamaged structure and types of pores. These results demonstrated that as-preparedcarbon materials have potentional application in symmetric capacitors.

“…Decomposition of coordination polymers and Metal-Organic Frameworks (MOFs) is a facile and reasonable procedure to obtain desired metal oxide nanomaterials with diverse morphologies [10][11][12]. For instance, Co 3 O 4 nanoparticles were prepared by direct calcination of fCo 3 (2, 3 (DMF) 4 Among metal oxide materials, molybdenum-based oxides are important from catalytic point of view since they serve as e ective catalysts for industrial reactions such as hydrodesulphurization of petrol, hydrogenation, oxidation, polymerization, and metathesis of ole ns [18,19].…”
