The catalytic performances of different CuZnAl catalysts prepared using copper nitrate, copper acetate and copper citrate for CO hydrogenation to higher alcohols (C2+OH) were studied in a slurry bed reactor. Among these catalysts, the Cu–N catalyst prepared using copper nitrate showed a relatively higher C2+OH selectivity and no obvious deactivation occurred during the lifetime test for 120 h. The influence of copper precursors on the performance of the CuZnAl catalysts was investigated by XRD, 27Al-MAS-NMR, N2 adsorption–desorption, H2-TPR, NH3-TPD, FT-IR and XPS techniques. The results indicated that the size of Cu0 particles, textural properties, the chemical state of Cu species, the amount of surface acid and chemical composition varied, which led to diverse catalytic activities toward C2+OH synthesis. It was concluded that Cu0, Cu+ and AlOOH were all necessary in ethanol and C2+OH synthesis when using the CuZnAl catalysts without promoters and the synergism of these species was beneficial to the formation of C2+OH. This work further demonstrated that alkalis and Fischer–Tropsch elements were not indispensable for C2+OH synthesis from syngas.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
