“…It is known that the active sites for C 1? production are those supported Co 0 metal crystallites [1][2][3][4][5]. Thus the active sites for CO 2 production might not be the Co 0 phase but be the support phase.…”

“…The Co/ZnAl 2 O 4 ÁAl 2 O 3 catalyst exhibits good resistance against steam sintering. [1][2][3][4][5][6][7][8][9][10][11] or hydrogenation of unsaturated organic feedstocks [12,13]. Complex oxides (e.g., AB 2 O 4 spinels) have better resistance against sintering/steam than simple oxides (e.g., silica or alumina) and can minimize the formation of metal-support compounds [14,15].…”

Literature about water addition over AB 2 O 4 spinel-supported cobalt CO hydrogenation catalysts is sparse. A comparative water addition experiment was conducted over Co/ZnAl 2 O 4 ÁAl 2 O 3 catalyst. Water addition may cause lower C 1 (i.e., CH 4 ) hydrocarbon distribution, lower C 2 -C 4 hydrocarbon distribution, higher C 5? hydrocarbon distribution and higher C 2 -C 4 olefin/paraffin ratio than the control test without water addition. Possibly, as a product of Fischer-Tropsch synthesis, water might have an autocatalytic effect for the FTS process to generate longer chain hydrocarbons via its facilitation of C-C coupling. The Co/ZnAl 2 O 4 ÁAl 2 O 3 catalyst exhibits good resistance against steam sintering. Graphical Abstract0 2000 4000 6000 10 20 30 40 50 60 70 80 90

“…Depositions of carbon is relevant (up to 40%), being Ni and Pd quite effective for the Boudouard reaction [14], even though their stability can be improved by tuning the support used [15][16][17][18]. Rhbased catalysts show superior H 2 selectivity compared to Pt [19] and are the most promising in methane CPO [7,20].…”

“…It hydrogenates synthesis gas, a mixture of H 2 and CO, into long‐chain hydrocarbons over supported metal catalysts, thereby producing high‐purity chemicals and fuels from sources other than crude oil. Additionally, the selectivity towards alkanes, alkenes and alcohols can be tuned by altering the catalyst composition or reaction conditions . The potential of this versatile reaction has resulted in extensive research using traditional spectroscopic techniques, e. g .…”

“…However, precise control over temperature (and pressure) is of tremendous importance for catalysis in order to mimic industrial conditions. Temperature differences of tens of degrees can cause a completely different product distribution within the Fischer‐Tropsch synthesis . As a consequence, an ideal miniaturized reactor allows for local control of temperature (and pressure), without affecting the optics in close proximity.…”

In Situ Local Temperature Mapping in Microscopy Nano‐Reactors with Luminescence Thermometry

In situ and operando experiments play a crucial role in understanding the mechanisms behind catalytic processes. In these experiments it is important to have precise control over pressure and temperature. In this work, we use luminescence thermometry to map the temperature distribution in a 300 μm microelectromechanical system nano‐reactor with a resolution of ca. 10 μm. These measurements showed a temperature gradient between the center and edge of the heater of ca. 200 °C (at Tset=600 °C) in vacuum and, in addition, a large offset of the local temperature of ca. 100 °C (at Tset=600 °C) in a non‐vacuum (i. e., air, He and H2) environment. The observed temperature heterogeneities can explain differences observed in the reduction behavior of Co‐based Fischer‐Tropsch synthesis catalyst particles at different locations in the nano‐reactor as determined by scanning transmission X‐ray microscopy.
