The conversion of carbon dioxide, an abundant and inexpensive feedstock to valuable
chemicals is a contemporary challenge with multiple facets. There is a need to elucidate the …

CO2 is a promising renewable, cheap, and abundant C1 feedstock for producing valuable
chemicals, such as CO and methanol. In conventional reactors, because of thermodynamic …

Hydrogen spillover phenomenon is well-documented in hydrogenation catalysis but still
highly disputed in hydrogen storage. Until now, the existence of hydrogen spillover through …

As CO2 emissions are sharply increasing, processes for converting CO2 into value-added
products are becoming more desirable. Ruthenium-based catalysts are the most active for …

CO2 methanation offers a promising route for converting CO2 into valuable chemicals and
energy fuels at the same time as hydrogen is stored in methane, so the development of …

The extensive utilization of fossil fuels has led to a rapid increase in atmospheric CO2
concentration, resulting in various environmental issues. To reduce reliance on fossil fuels …

Methanation is capable of chemical storage of fluctuating renewable energy, which requires
fundamental understanding of the dynamics of the kinetic processes taking place on the …

Two main challenges involved in heterogeneous catalytic CO 2 reduction are:(a) decreasing
the consumption of H 2 to the minimum required level with possibly the maximum CO 2 …
