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.

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 production of methanol (CH3OH) from CO2 is an attractive solution for closing the carbon cycle and thus addressing both environmental concerns raw material changes in chemical industry. CuZn-based catalysts are most intensively investigated materials this regard but suffer CH3OH decomposition to CO with increasing conversion. Pd-containing also show promising performance, they less understood a mechanistic point view. To bridge gap, series based on CeO2, ZrO2, Ce0.8Zr0.2O2, or CeO2–SiO2 supports Pd CuZnPd as active components were prepared. Comprehensive kinetic tests revealed that containing only species convert exclusively, followed by hydrogenation CH3OH. Using feed consisting H2, 100% selectivity was achieved. role generate surface which involved probably support. In situ Fourier transform infrared spectroscopy have identified HCOO– formed gas-phase precursors contrast Pd/support catalysts, their CuZnPd/support counterparts directly into parallel CO. These differences explained structural/electronic due alloying Cu X-ray photoelectron absorption spectroscopy. Overall, study enhances understanding aspects product formation course highlights significance steady-state catalytic at different space velocities identify primary secondary pathways, offering valuable insights tailored design efficient CO2.
