Promotion of the HCHO oxidation over gold supported on Co-promoted ceria catalysts can be related to the higher concentration of oxygen vacancies and an improvement in the redox properties, which can contribute to the better activation of O 2 and an enhancement of the oxygen mobility. Historical records and family trees related to Barthélémie Sambardier.

Jeanne was born on February 22 1743, in Martigné-Briand, Maine-Et-Loire. Guillaume was born on October 2 1741, in Thouarcé, Maine-Et-Loire. X-ray photoelectron spectroscopy (XPS) characterization of the fresh catalysts indicated that the Au species were mainly in a slightly ionic δ + valence state, but did not exclude the possibility of metallic gold. François Nicolas ROCHARD was born on month day 1779, in birth place, to Guillaume Louis Augustin ROCHARD and Jeanne LEBRETON. Based on the HCHO amount (in μmol) converted into CO 2 per gram of gold per second after 40 h on stream, the 1.5Au/CeCo catalyst demonstrated the best activity (∼3.9) as compared to the other catalysts (≤2.0). 04:00 - 07:53 8 Races 04:0004:3005:0005:3206:0706:4007:1007:53 Les. ![]() The 3 wt% Au catalysts demonstrated a higher HCHO conversion than their low-gold counterparts (1.5 wt% Au), a remarkable improvement in the HCHO conversion was observed using Co-promoted ceria (9 mol%). All of the supported Au catalysts exhibited HCHO oxidation into CO 2 at 25 ☌ and demonstrated a great stability for the time on stream (40 h).

The fresh supported Au catalysts were characterized using several techniques in order to investigate their morphological, structural and redox properties before being tested for formaldehyde (HCHO) total oxidation. Renaud Cousin CuAlCe oxides were obtained from hydrotalcite-type precursors by coprecipitation using a M 2+ /M 3+ ratio of 3. Au catalysts with loadings of 1.5 and 3 wt% were dispersed over CeO 2 and Co (9 12 mol%) promoted CeO 2, using the deposition–precipitation method, followed by calcination at 350 ☌.
