Controllable transformation from 1D Co-MOF-74 to 3D CoCO₃ and Co₃O₄ with ligand recovery and tunable morphologies: the assembly process and boosting VOC degradation

Abstract

The controllable assembly of three-dimensional (3D) nano materials from one-dimensional (1D) precursor has always been one of the difficulties in nano material synthesis. Here, we use a gentle hydrolysis of...

Modulating defective oxygen of Co-based crystals by calcination temperature control for improving the catalytic removal of propane

“…After deconvolution, the peaks at ∼779.6 and ∼794.7 eV are attributed to Co 3+ , and those at ∼780.9 eV and ∼796.2 eV are attributed to Co 2+ . [31][32][33] Fig. 3b shows the peaks of defective oxygen and lattice oxygen.…”

Exploration of atomic interfaces with inherent oxygen vacancies in zirconia for toluene oxidation

“…21,36 Evidently, with an increasing Ce molar percentage from 3 to 10%, these reduction peaks shied to a lower temperature and whole H 2 consumption signicantly increased, indicating that a higher amount of heteroatom insertion induced a more reducible and reactive surface, probably due to the extensive atomic interfaces with defects in CeZr-x catalysts. 37,38 O 2 -TPD proles of all samples are displayed in Fig. 4b.…”
