MOF-on-MOF heterojunction-derived Co₃O₄–CuCo₂O₄ microflowers for low-temperature catalytic oxidation

Abstract

Through exchange-extended growth method (EEGM), MOF-on-MOF heteroarchitectures with distinct crystallography were produced and pyrolyzed into hybrid metal oxides. The strong exchange ability of organometallic compounds realized the component reconstruction of...

MOF‐on‐MOF‐Derived Hollow Co3O4/In2O3 Nanostructure for Efficient Photocatalytic CO2 Reduction

“…Additionally, the diffraction peaks observed at 36.8°, 44.8°, 59.4°, and 65.2° in H‐Co 3 O 4 and H‐Co 3 O 4 /In 2 O 3 correspond to the (311), (400), (511), and (440) crystal planes of cobalt oxide (PDF#43‐1003), respectively. [ 33 ] The (222) and (440) planes of indium oxide (PDF#44‐1087) were also observed for H‐Co 3 O 4 /In 2 O 3 , [ 34 ] confirming the successful synthesis of the bimetallic oxides (Figure 3i ). As shown in Figure 3j and Table S4 (Supporting Information), H‐In 2 O 3 exhibited type‐I adsorption similar to that of H‐InOF‐1, but with a significant decrease in sorption capacity, and H‐Co 3 O 4 exhibited a significantly reduced pore volume.…”

Enhanced Enzymatic Performance of Immobilized Pseudomonas fluorescens Lipase on ZIF-8@ZIF-67 and Its Application to the Synthesis of Neryl Acetate with Transesterification Reaction

“…MOF@MOF is a mixed framework formed by various chemical interactions between different MOFs that often has a core shell or a layered heterostructure. Due to the good synergistic effect among different MOFs materials, these hybrid frameworks often exhibit multifunctional properties and are widely used in wastewater treatment, chemical catalysis, and sensor detection [ 18 , 19 , 20 ]. Zeolitic imidazolate frameworks (ZIFs) are the most commonly studied materials for MOF@MOF.…”

Construction of 2D C,N-co-doped ZnO/Co3O4over Ni(OH)2mesoporous ultrathin nanosheets on Ni foam as high-performance electrocatalysts for benzyl-alcohol oxidation and accelerating hydrogen evolution

“…30 Wang et al reported a P-NiO/NiCo 2 O 4 nanocube that shows a remarkable electrocatalytic activity for the OER and good long-life stability for 20 h. 31 In addition, it is worth noting that the easily prepared nickel hydroxide (oxide) 2D nanosheets could provide more active sites, correspondingly, increasing their electrocatalytic activity during the electrooxidation reaction under alkaline conditions. [32][33][34][35][36] This will facilitate to achieve the highly efficient electrocatalysts for the BOR using 2D Zn-Co ZIF as a template combined with 2D Ni(OH) 2 nanosheets. To the best of our knowledge, this 2D multiheterojunction mesoporous structure has not been reported yet.…”
