Recently, Liu Jian, a researcher from the State Key Laboratory of Catalysis Fundamentals, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, published the title "Nanoengineering Carbon Spheres as Nanoreactors for Sustainable Energy Applications).
Colloidal carbon ball nanoreactors have attracted widespread attention, mainly because of its excellent properties: 1. Large surface area and controllable surface function; 2. Excellent electrical conductivity can provide electronic channels; 3. Adjustable porosity and The size of the particles is convenient for mass transportation; 4. Long-term stability is easy to operate. Using the nanoreactor as a clue, the team systematically summarized the latest research results, focused on the nano-customization of carbon spheres and the construction of nanoreactors, and detailed the energy storage and electrochemistry of carbon sphere-based micro / nano reactor Applications in conversion and catalysis, and present challenges and future development prospects in this field.
The team of Yang Qihua, a researcher at Dalian Institute of Chemical Physics, and Li Can, a member of the Chinese Academy of Sciences, proposed the concept of nanoreactors earlier in the world and have made a series of progress in the construction of nanoreactors. However, there is still insufficient understanding in the academic community regarding the characterization of nanoreactor materials, reactor design, catalytic microscopic mechanism of action, and diffusion and transfer models in nanoreactors. In response to the above key scientific issues, Liu Jian led the research team to successfully build a series of sub-micron reactors with egg yolk-egg shell nanostructures. This series of micro / nano reactors are used in the catalytic hydrogenation of nitroarene, phenylacetylene hydrogenation, and levulinic acid. Hydrogenation, methane dry reforming, electrocatalysis and other reactions all show specific energy, and it is found that the spatial confinement effect significantly improves activity, selectivity and stability (Adv. Funct. Mater., 2018; Adv. Sci., 2019 ); In collaboration with Yang Qihua, it was found that there is spatial microenvironment regulation in the micro-nano reactor, which can regulate the catalytic reaction process in the nanoreactor (Angew. Chem. Int. Ed., 2019; Chem. Eng. J., 2019); Revealed the coupling of space-time coupling of the catalytic reactions in series in the nanoreactor (NPG Asia Mater., 2016; Angew. Chem. Int. Ed., 2017).
The above work was supported by the Cooperation Fund of the Institute of Clean Energy Innovation of the Chinese Academy of Sciences and the Xingliao Talent Program, etc., and was recently published in Advanced Materials.
