Catalytic oxidation of toluene and p-xylene using gold supported on Co3O4 catalyst prepared by colloidal precipitation method

Enhancing Gas Response Characteristics of Mixed Metal Oxide Gas Sensors

“…[17][18][19] This is consistent with the fact that the porous Co 3 O 4 sensor in this study shows a relatively high level of responses to xylene, toluene, and benzene. Therefore, when porous Co 3 O 4 (whose response to xylene, toluene, and benzene is outstanding) is used, it will be easier to measure the five major indoor pollutants with a single sensor.…”

Excellent catalytic performance, thermal stability, and water resistance of 3DOM Mn2O3-supported Au–Pd alloy nanoparticles for the complete oxidation of toluene

“…Table S1 lists the catalytic activities at 160 o C of various samples reported in the literature for toluene oxidation under different conditions. Apparently, toluene oxidation rate over 3.8AuPd 1.92 /3DOM Mn 2 O 3 (10.5 μmol/(g noble metal s)) was much higher than that (1.80 μmol/(g noble metal s)) over 3.4Au/3DOM La 0.6 Sr 0.4 MnO 3 [12], that (1.14 μmol/(g noble metal s)) over 1.0Pt/Al 2 O 3 CeO 2 [26], that (4.54 μmol/(g noble metal s)) over 0.3Pd/Al 2 O 3 [27], that (0.00059 μmol/(g noble metal s)) over 1.6Au/Co 3 O 4 [28], that (4.91 μmol/(g noble metal s)) over 3.7Au/meso-Co 3 O 4 [29], and that (5.70 μmol/(g noble metal s)) over 1.99AuPd/3DOM Co 3 O 4 [25], but much lower to that (22.7 μmol/(g noble metal s)) over 0.5Au−0.5Pd/CeO 2 [16].…”

Facile synthesis, magnetic and optical properties of double-shelled Co3O4 hollow microspheres

“…2b), which is particularly important to confirm or disprove the existence of oxygen vacancies. The peaks at 532.98 and 531.08 eV should be attributed to the oxygen vacancies existing in Co 3 O 4 crystals, while the weak one at 529.58 eV corresponds to the original lattice oxygen species in Co 3 O 4 [30].…”
