“…Initially, the first reports of such in situ infrared based measurements, concentrated upon the interactions of CO 2 , H 2 , and reaction mixtures thereof, and in 1983 this led to the first study that attempted to correlate aspects of what could be observed using midrange infrared with measurements with the activity for the production of methanol. 172 Figure 18a shows a schematic of the transmission infrared cell used and Figure 18b, the intensity of the IR absorption due to carbon monoxide at around ca. 2130 cm −1 .…”

“…These early investigations were limited to low pressures and temperatures. That said, FT-IR was starting to be applied in specially constructed reaction vessels − to permit the sorts of experimental investigations that today we would recognize as “in situ” and even “operando”, made at elevated pressures and temperatures. ,− …”

The activity and durability of the Cu/ZnO/Al 2 O 3 (CZA) catalyst formulation for methanol synthesis from CO/CO 2 /H 2 feeds far exceed the sum of its individual components. As such, this ternary catalytic system is a prime example of synergy in catalysis, one that has been employed for the large scale commercial production of methanol since its inception in the mid 1960s with precious little alteration to its original formulation. Methanol is a key building block of the chemical industry. It is also an attractive energy storage molecule, which can also be produced from CO 2 and H 2 alone, making efficient use of sequestered CO 2 . As such, this somewhat unusual catalyst formulation has an enormous role to play in the modern chemical industry and the world of global economics, to which the correspondingly voluminous and ongoing research, which began in the 1920s, attests. Yet, despite this commercial success, and while research aimed at understanding how this formulation functions has continued throughout the decades, a comprehensive and universally agreed upon understanding of how this material achieves what it does has yet to be realized. After nigh on a century of research into CZA catalysts, the purpose of this Review is to appraise what has been achieved to date, and to show how, and how far, the field has evolved. To do so, this Review evaluates the research regarding this catalyst formulation in a chronological order and critically assesses the validity and novelty of various hypotheses and claims that have been made over the years. Ultimately, the Review attempts to derive a holistic summary of what the current body of literature tells us about the fundamental sources of the synergies at work within the CZA catalyst and, from this, suggest ways in which the field may yet be further advanced.
