Nano Energy article featured in the News

In collaboration with researchers at Rice University and the group of Prof. Bao at the UH, graduate student Hari Thirumalai has provided a theoretical explanation why a triple-layer FeMnP catalyst works well for hydrogen evolution during water splitting. In fact, experiments done by Dr. Zhenhuan Zhao demonstrate that the same material also works for the oxygen evolution reaction. Thus, this new, cheap and scalable material could be used as anode and cathode for electrocatalytic water splitting and efficient hydrogen production.

Artwork selected for cover of Special Issue in ChemCatChem!

2017 ChemCatChem Cover
Our contribution to the special issue on "Catalysis for New Energy Technology" was selected for the journal cover of ChemCatChem. The work originated from a collaboration with Bill Epling's group and the cover shows the electron density change in methane during its activation over a palladium catalyst. Hieu Doan created the artwork with the help of Dr. Martin Huarte-Espinosa at the UH Center for Advanced Computing and Data Systems. More info about the cover artwork and the article itself is available in the cover profile.

Artwork selected for cover of Chemistry: A European Journal

Graduate student Arian Ghorbanpour, co-advised by Prof. J. Rimer, has contributed computational results that explain the sorption behavior of ultrastable zeolite GIS polymorphs. In particular, his work shows that GIS is not a good framework structure for carbon dioxide sorption; instead, it is an excellent framework structure to separate water from other small molecules. The full article was published in Chemistry: A European Journal and is featured on the journal cover. Congratulations Arian!

Article on CO oxidation over gold catalysts receives Best Fundamental Paper Award from the AIChE South Texas Section

AIChE-STS Best Fundamental Paper Award

Why are Ru/TiO2 catalysts so selective for direct deoxygenation?

H2 cleavage on RuTiO2
Graduate student Byeongjin Baek's computational work on elucidating the mechanism of direct deoxygenation of phenolic compounds on Ru/TiO2 catalysts has resulted in a new understanding of the roles of the support and the ruthenium metal nanoparticle. We find that for the selective C-OH cleavage to occur, it is necessary that the support can provide a proton to weaken the C-O bond. In turn, the proton must be regenerated, which can occur by heterolytic H2 splitting across the Ru/TiO2 interface (see figure). Our results were published in ACS Catalysis and are important to further improve deoxygenation catalysts and enable a hydrogen-efficient upgrade of bio-oil into transportation fuel. Byeongjin's DFT work at UH was supported by a DOE Early Career Award.
