Bimetallic metal–organic frameworks derived hierarchical flower-like Zn-doped Co3O4 for enhanced acetone sensing properties

General synthesis of CoCeMOx trimetallic oxides via a cation exchange reaction for the oxygen evolution reaction

“…S15†) shows that the diffraction peaks of CoCeZnO x PNs are shifted to a lower angle compared to the CoCe-oxides. This is due to the fact that the ionic radius of Zn 2+ (0.74 Å) is larger than that of Co 3+ (0.63 Å), and the lattice stripe becomes larger after the Zn atom replaces the Co atom in the lattice of Co 3 O 4 , 32,33 which indicates that the Co 3 O 4 porous nanospheres co-doped with CeO 2 and the Zn element are successfully obtained. The high-resolution TEM (HRTEM) image (Fig.…”

Three-dimensional hierarchical flower-like bimetallic–organic materialsin situgrown on carbon cloth and doped with sulfur as an air cathode in a microbial fuel cell

“…The Zn/Co-3DHFLM catalysts were synthesized under solvothermal conditions in an improvement on the previous material preparation method. 25 Specifically, Co(NO 3 ) 2 ·6H 2 O (0.8370 g) and Zn(NO 3 ) 2 ·6H 2 O (0.0469 g) were dissolved in 25 ml of methanol (CH 3 OH) to form solution A, and 2-methylimidazole (0.328 g) was dissolved in 25 ml of CH 3 OH to form solution B. After thorough dispersion by sonication, solution B was quickly added to solution A to form a mixture, which was stirred magnetically for 15 min.…”

PtPd NPs-functionalized metal–organic framework-derived α-Fe2O3 porous spindles for efficient low-temperature detection of triethylamine

“…Among these, O V and O C play key roles in gas-sensing performance. 34,35 The percentages of different oxygen species are shown in Table S2. † The relative percentage of O L decreased and the percentages of O V and O C increased for the materials modified with noble metals.…”
