In a broader context, there are other examples in which metal oxide surface remain during electrochemical CO2 reduction, even though the Pourbaix diagram suggests that the metallic phase is thermodynamically stable47,48. We propose that the CoO clusters are ligand-stabilized CoO to the point that,...
During the process of carbon dioxide injection into the target layer (usually at a depth of 800–3000 m), both the temperature and the pressure exceed the critical point of the carbon dioxide phase diagram (31.1 °C and 73.9 bars), as shown in Figure 4, and the carbon dioxide is in a...
In the chromaticity diagram, the value of a* chickpea cooked was higher than the raw chickpea, which means that the value has tones closer to the red tones than the raw sample; therefore, the cooked chickpea is more intense than the raw. The same happens with the parameter b*, where ...
(Figs.2BandS25), manifesting once again the importance of the Co-Npyrcovalent bond to avoid catalyst detachment. The use of barep-CTF-pyorp-CTFmixed with dissolvedCoTCPcin the parallel systems could not initiate the formation of CO as well (TableS5), which highlights the importance of pre-...
3.3.1. Optimizing M–Ch covalent bonds Strengthening the surface M–Ch covalent bond could be an efficient strategy to stabilize the structure of active sites on PMC-based catalysts. For instance, Gao and coworkers developed a ZnIn2S4 nanoflower catalyst by hydrothermal synthesis (Fig. 6a) [25...
