“…CO and O 2 adsorption microcalorimetric experiments were carried out with a BT 2.15 heat‐flux calorimeter as described previously . In detail, the calorimeter was connected to a gas handling and a volumetric system employing MKS 698A Baratron Capacitance Manometers for the pressure measurement (±1.33 × 10 −2 Pa).…”

This work reported the adsorption and reaction performance of FeOx supported subnanometer cluster and single‐atom Ir catalysts for the oxidation of CO at low temperature. By varying the pretreatment temperature and Ir loading, the single‐atom and subnanometer cluster Ir catalysts were obtained. The Ir subnanometer clusters exhibited higher activity for the oxidation of CO with or without the presence of H2 than the single‐atom counterpart. By using adsorption microcalorimetry and in situ infrared spectroscopy measurements, it was found that the Ir subnanometer clusters not only promoted the adsorption and reaction of CO and O2 but also facilitated the formation of OH species from reaction between H2 and O2, thus opening a new reaction pathway between CO and OH species to produce CO2 compared with that between CO and O species on the single‐atom counterpart. © 2017 American Institute of Chemical Engineers AIChE J, 63: 4003–4012, 2017

“…CO adsorption was carried out with a BT2.15 heat-flux calorimeter as described earlier [21]. Prior to the measurement, a catalyst sample was preheated in a special treatment quartz cell in NH 3 from room temperature to 700°C and held at that temperature for 0.5 h. Then, the sample was outgassed in the cell at 400°C for 1 h under high vacuum.…”

Alumina supported cobalt nitride [Co 4 N-Al 2 O 3 (HT)] with high cobalt loading has been prepared for the first time from Co-Al hydrotalcite precursors. The formation of the Co 4 N phase was confirmed by XRD, H 2 -TPR, and XPS. Compared with Co 4 N/Al 2 O 3 (IMP) prepared by conventional impregnation and nitriding, the hydrotalcite derived catalyst exhibited a much better activity for hydrazine decomposition as consequence of higher dispersion of active species.

“…Transmission electron microscopy (TEM) analyses were performed on a JEM-2000EX (JEOL) microscope. Microcalorimetry of CO adsorption was performed at 40°C using a Calvet-type microcalorimeter (Setaram BT 2.15) as described in detail elsewhere [11,19].…”

Activated carbon (AC) supported tungsten carbide was reported for the catalytic decomposition of hydrazine for the first time. It was found that the WC x /AC-H catalyst prepared by a carbothermal hydrogen reduction process exhibited excellent catalytic performances both in the microreactor and in a 1 Newton hydrazine microthruster. The XRD, TEM and microcalorimetry results suggest that the formation of well crystallized W 2 C phase, the restraining of the carbon deposition, as well as the prohibiting of the methanation should be responsible for the high activity and stability of the WC x /AC-H catalyst in the hydrazine decomposition reaction.
