Congratulations Alex Tavasoli on your Commentary in Joule,”Green Syngas by Solar Dry Reforming: Killing Two Greenhouse Gases with One Stone”!
A photothermal dry reforming process has been developed that efficiently transforms two potent greenhouse gases, CH4 and CO2, into industrially valuable synthesis gas (a mixture of CO and H2), using a uniquely structured nickel-silica nanoscale catalyst that is impressively resistant to deactivation by coking. This exciting new discovery provides an opportunity to “kill two greenhouse gases with one stone.”

Congratulations Yuchan Dong and Kulbir Ghuman and Co-Authors on your Advanced Science Paper Entitled Tailoring Surface Frustrated Lewis Pairs of In2O3-x(OH)y for Gas-Phase Heterogeneous CO2 Hydrogenation by Isomorphous Substitution of In3+ with Bi3+
The excited state acidity and basicity of the surface frustrated Lewis pair, in oxygen vacancy and hydroxide defect-laden BizIn2-zO3-xOHy, can be chemically tailored, by controlling the level of isomorphous substitution of Bi(III) for In(III) in the Bixbyite crystal lattice. This makes it possible to optimize the catalytic performance of the solar powered reverse water gas shift reaction, CO2 + H2O –> CO + H2O.

Well done Ab on your solar fuels paper published in Advanced Energy Materials, January 2018, where you demonstrate a highly efficient ambient temperature Solar Sabatier process whereby CO2 photomethanation is catalyzed by nanostructured RuO2 on a silicon photonic crystal support at the remarkable rate of 4.4 mmol gcat-1h-1. This exceptional photomethanation rate is due to the large surface area coupled with the unique light-trapping and broadband optical absorption properties of the photonic crystal support.

Zheng-Min Wang, Wendong Wang and Geoffrey Ozin have discovered a synthetic pathway to a sandwich-type nanocomposite of reduced graphene oxide and periodic mesoporous silica in which mesochannels of silica vertically align with respect to the graphene layers with tunable mesochannel depth and size. Deep insight into the formation mode of this novel class of materials obtains from a high photon flux small angle X-ray scattering technique and zeta potential-based solution chemistry, Advanced Functional Materials 2017, DOI: 10.1002/adfm.201704066

Austria’s Museum of Applied Arts in Vienna opening in December will showcase a diorama of Prof. Ozin’s vision of a closed carbon cycle.

Congratulations Annabelle, Wei and Chenxi as well as Ab, Yuchan and Ziqi on your Advanced Sustainable Systems paper entitled Tailoring CO2 Reduction with Doped Silicon Nanocrystals!!
In this work, silicon nanocrystals doped with varying combinations of phosphorous and boron were investigated for the heterogeneous photoreduction of CO2. The observed trends in stability and activity open new pathways towards the development of sustainable CO2 conversion catalysts.
