Gas sources rich in CO2 derived from biomass/waste gasification, anaerobic digestion, or industrial carbon capture often contain impurities such as H2S, H2O, and NH3, which can significantly hinder catalyst performance. Here, we show the role of NH3 on reverse water-gas shift (RWGS) reaction over a commercial Cu/ZnO/Al2O3 catalyst, examining its effects both catalytic activity structure. We found that reversibly decreases conversion immediately by suppressing carbonate hydrogenation CO desorption. This effect intensifies with an increase concentration but at higher temperatures. However, prolonged exposure (over 100 h) to RWGS conditions presence 1.4% leads near-total irreversible deactivation catalyst. Under exposure, loses Cu+ sites surface, causing spatial separation Cu ZnO. Finally, address this challenge, propose novel strategy mitigate inhibition decomposing into N2 H2.

Converting CO2 and green hydrogen into products such as methane methanol not only has a negative carbon effect, but also stores renewable energy chemicals. This represents promising route for storage technologies. The hydrogenation of to methanol, which represent strongly exothermic reactions, are thermodynamically favored at low temperatures. However, the inherent inertness makes it difficult activate Both reactions face challenge activating temperature, so catalysts exhibiting high activity under conditions critical need. Layered double hydroxides (LDHs) have attracted considerable interest owing their regular layered structure uniform dispersion multiple metallic components. there few studies on same effects promoters over LDHs-derived catalysts. Here, we investigated two in different illustrate facilitating low-temperature activation By adding Fe Mn NiAl-Fe CuZnAl-Mn, crystal lattices were expanded, surface areas increased 38% 25%, reduction temperatures decreased 97 °C 10 °C, respectively.

The CuZnOAl2O3 catalyst shows excellent activity and selectivity in the reaction of CO2 hydrogenation to methanol as a consequence its controllable physicochemical properties, which is expected offer an efficient route renewable energy. In this study, catalysts are engineered by special pretreatment, constructing carbonate structure on surface catalyst. Compared unmodified catalyst, optimized (CZA-H-C1) not only exhibits improved 62.5% (250 °C 3 MPa) but also retains minimal degree deactivation 9.57% over 100 h period. By characterizing with XRD, TEM, XPS situ DRIFTS spectroscopy, it was found that species Cu-based could significantly enhance shield active sites. This study offers theoretical insights practical strategies for rational design optimization high-performance heterogeneous catalysts.
