Solvent-Free Synthesis of CuO/HKUST-1 Composite and Its Photocatalytic Application

Abstract

A metal−organic framework (MOF) is one kind of crystalline microporous material and is increasingly used as a host of catalytically active guests. Nanostructured materials supported on MOFs have presented enhanced catalytic activity and stability. Templates or several steps are essential to the synthesis of MOF composites. Simple and effective MOF synthesis methods are still challenging. Nanosized copper oxide particles in MOF composites, described as nanosized CuO@HKUST-1, were prepared by a facile solvent-free reaction. These series of CuO@HKUST-1 composites exhibited excellent photocatalytic activity for production of hydrogen and methylene blue (MB) degradation under visible light. This synthesis method provides an effective way to fabricate MOFrelated nanocomposite catalysts.

Metal oxide integrated metal organic frameworks (MO@MOF): rational design, fabrication strategy, characterization and emerging photocatalytic applications

“…In addition to these, Jin et al prepared CuO/HKUST-1 via a one-pot solvent free route from nano-CuO precursors in which CuO and H 3 BTC linkers were ground together followed by heat treatment at 180°C leading to a hybrid where CuO NPs were trapped in the MOF matrix. 48…”

Photocatalytic Degradation of Diazinon with a 2D/3D Nanocomposite of Black Phosphorus/Metal Organic Framework

“…where E VB , E CB are, respectively, the valence and conduction band potentials, E 0 is approximately 4.5 eV, defined as the energy of free electrons vs. normal hydrogen electrode and X is the electronegativity of the semiconductor, calculated from the geometric average of the electronegativity of elemental atoms [22]. The electronegativity of MIL-125(Ti) was computed to be 6.58 eV while that of FLBP was 4.67 eV.…”

“…The exploration of 2D/MOF composites for photocatalytic applications by taking advantage of the catalytic properties of MOFs and the fast carrier mobility of 2D materials is an exciting field [21,22]. However, not much work has been focused on the application of these composites in the removal of diazinon in water.…”

Mechanistic and Experimental Study of the CuxO@C Nanocomposite Derived from Cu3(BTC)2 for SO2 Removal

“…Cu 3 (BTC) 2 (BTC = benzo−1,3,5−tricarboxylate) (namely, MOF−199 and HKUST−1), as a representative copper-based MOF (Cu−MOF) material, is widely used in many fields, such as catalysis, sensors, gas separation and storage, due to its structurally characteristic pores and highly active open metal sites [5,[30][31][32]. Jin et al reported that a Cu−MOF−supported composite (CuO@HKUST−1) had enhanced photocatalytic activity and stability over methylene blue dye degradation [33].…”
