TLDR
In this paper, the role of CO2 in the dehydrogenation of ethane over Ga2O3-loaded catalysts was examined, and it was found that CO2 markedly promoted the degradation of the product (ethene) from the catalyst surface.About:

C−H Bond Activation and Organometallic Intermediates on Isolated Metal Centers on Oxide Surfaces
TL;DR: This work focuses on processes involving C-H bond activation of alkanes and aromatics on isolated metal centers of surfaces on oxide materials leading to organometallic species and/or intermediates in heterogeneous catalysis.
Journal ArticleDOI
Dehydrogenation of propane to propene over different polymorphs of gallium oxide
TL;DR: In this paper, the authors investigated the catalytic activity of four polymorphs of gallium oxide in the presence or absence of CO 2 and showed that β -Ga 2 O 3 exhibits the highest activity among the polymorphs, and it is even more active than chromium oxide catalyst.
Journal ArticleDOI
Carbon dioxide utilization as a soft oxidant and promoter in catalysis
TL;DR: The use of CO2 as a soft oxidant and promoter is a promising concept for industrial applications that could not only contribute to the mitigation of CO 2 levels, but also the development of economical and energy efficient syntheses of various chemicals.
Journal ArticleDOI
Direct Synthesis of Gallium Oxide Tubes, Nanowires, and Nanopaintbrushes
TL;DR: Results showed that multiple nucleation and growth of gallium oxide nanostructures could easily occur directly out of molten gallium exposed to an appropriate composition of hydrogen and oxygen in the gas phase.
