Recent developments in hydraulic fracturing have not only increased non-traditional supply of petroleum for fuels, but also opened up doors for unprecedented revolution in the utilization of shale gas hydrocarbon reserves. This abundant and previously untapped source of hydrocarbons has already made significant shift in the natural gas supply, yet the vast potential for economical production of electricity, value-added chemicals and fuels for the next century still remains to be realized.  There exist daunting technical challenges toward efficient shale gas conversion; innovative scientific and/or engineering approaches, most likely in collaborative team efforts, need to be exploited to successfully tackle these challenges.

This special forum on shale gas conversion at UKC 2019 will serve as the first stepping stone for SK’s drive to promote technological advances and open innovation among researchers from industry and academia in Korea and the U.S. alike.  Particularly, one of the World’s top experts in heterogeneous catalysis along with two emerging investigators will offer invited talks providing broad and insightful perspectives as well as sharing transformative scientific discoveries on topics ranging from single atom and alloy catalysis to novel membrane reactors. Ample discussions and networking opportunities through this forum are expected to trigger exciting interactions and collaborations toward next generation approaches in efficient and scalable shale gas hydrocarbon conversion.

Identification of the active catalytic site and design of catalysts with 100% atom efficiency has been a long-standing goal in heterogeneous catalysis. A promising approach to reaching this goal through the controlled preparation of isolated single-atom heterogeneous catalysts has emerged in the recent literature. For catalytic metals, atomic dispersion affords better utilization, different (often better) selectivity than the extended metal, and new prospects for low-cost and green process development. Isolated supported metal atoms may be viewed as species bonded to a support, the latter serving as a ligand. An analogy between a homogeneous and a heterogeneous single-site catalytic center can thus be made. Single atom sites catalyze some, but not all reactions. It is crucial to understand the mechanisms behind catalysis by supported single metal atoms, as this will guide the new, improved catalyst designs.

In this presentation, suitably stabilized catalytic sites as single metal atoms/cations on various supports will be showcased drawing examples from a variety of reactions, including the low-temperature water-gas shift reactions; methanol and ethanol dehydrogenation and steam reforming reactions; the direct methane conversion to oxygenates; and selective hydrogenation reactions on single-atom alloys. Reaction mechanisms involving single metal atoms/cations often transcend support structure and composition, thus allowing flexibility in the choice of the support. A unique “signature” of the metal (Au, Pt, Pd, Ni, etc.) at the atomic state is preserved, distinct however from the corresponding extended metal catalyst.  Novel synthesis methods will be discussed as will be the stability of single-atom metal catalysts in various supports and reaction environments.
