Ultrafast synthesis of HKUST-1 nanoparticles by solvothermal method: properties and possible applications

Abstract Although an astounding variety of Metal-Organic Frameworks (MOFs) has been synthesized so far, the search for fast and efficient methods that yield greener and superior crystalline structures is yet an ongoing challenge. For the first time, the Hong Kong University of Science and Technology (HKUST-1) MOF has been synthesized by an efficient non-conventional solvothermal method through a Monowave 50 (Anton Paar) reactor. The synthesis has been carried out at 5, 10, 15, and 30 min instead of staggering times of 10 to 24 h. Its crystalline structure, crystallite size, morphology, particle size, specific surface, and optical properties have been characterized. The presumed presence of monocrystalline structures along with a roughly band gap energy at 3.5 eV makes them compelling nanostructures for a variety of applications.
