Abstract:
Ethylene and propylene serve as the basic platform chemicals in the chemical industry. Research on their production has garnered significant interest. One of them is the dehydrogenation of light alkanes with the oxidative promotion of CO2. This process can simultaneously produce light olefins and achieve resource utilization of CO2. Pt-based catalysts, extensively used in the direct dehydrogenation of light alkanes, are expected to show activity potential in the CO2 oxidative dehydrogenation (CO2-ODH) of light alkanes. However, research on Pt-based catalysts for CO2-ODH of light alkanes remains limited, and no systematic review has been reported yet. Here, the advancements in Pt-based catalysts for the CO2-ODH of ethane and propane are reviewed, including (i) reaction mechanisms, (ii) rational design strategies for efficient and stable Pt-based catalysts, and (iii) emerging reaction processes and optimization methods. Perspectives on fundamental challenges and future research are proposed. Among them, machine learning-guided design of Pt-based catalysts will be an important research direction in the future.

Conformations of Ethane and Propane
Staggered conformation is a low energy and more stable conformation with the C-H bonds on the front carbon placed at 60°dihedral angles relative to the C-H bonds on the back carbon, leading to a reduced torsional strain. In staggered...

Variation of Atmospheric Pressure
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
