Journal ArticleDOI
A noble-metal-free, tetra-nickel polyoxotungstate catalyst for efficient photocatalytic hydrogen evolution.
Hongjin Lv,Weiwei Guo,Kaifeng Wu,Zheyuan Chen,John Bacsa,Djamaladdin G. Musaev,Yurii V. Geletii,Sarah M. Lauinger,Tianquan Lian,Craig L. Hill +9 more
TL;DR: Under minimally optimized conditions, Ni4P2 catalyzes H2 production over 1 week and achieves a turnover number of as high as 6500 with almost no loss in activity.
Journal ArticleDOI
In Situ Probes of Capture and Decomposition of Chemical Warfare Agent Simulants by Zr-Based Metal Organic Frameworks
Anna M. Plonka,Qi Wang,Wesley O. Gordon,Alex Balboa,Diego Troya,Weiwei Guo,Conor H. Sharp,Sanjaya D. Senanayake,John R. Morris,Craig L. Hill,Anatoly I. Frenkel +10 more
TL;DR: Diffraction measurements indicate that all four MOFs adsorb DMMP within the pore space, and the combination of X-ray absorption and infrared spectra suggests direct coordination of DMMP to the Zr6 cores of all MOFs, which ultimately leads to decomposition to phosphonate products.
Journal ArticleDOI
Mechanism and Kinetics for Reaction of the Chemical Warfare Agent Simulant, DMMP(g), with Zirconium(IV) MOFs: An Ultrahigh-Vacuum and DFT Study
Guanyu Wang,Conor H. Sharp,Anna M. Plonka,Qi Wang,Anatoly I. Frenkel,Weiwei Guo,Craig L. Hill,C. Smith,J. Kollar,Diego Troya,John R. Morris +10 more
TL;DR: In this paper, the mechanism and kinetics of interactions between DMMP and Zr6-based metal organic frameworks (MOFs) have been investigated with in situ infrared spectroscopy (IR), X-ray photoelectron spectra (XPS), powder Xray diffraction (PXRD), and DFT calculations.
Journal ArticleDOI
Broad‐Spectrum Liquid‐ and Gas‐Phase Decontamination of Chemical Warfare Agents by One‐Dimensional Heteropolyniobates
Weiwei Guo,Hongjin Lv,Kevin P. Sullivan,Wesley O. Gordon,Alex Balboa,George W. Wagner,Djamaladdin G. Musaev,John Bacsa,Craig L. Hill +8 more
TL;DR: Three lines of evidence establish that KGeNb removes DMMP, and thus likely GB/GD, by general base catalysis, andHydroxide is far less active against the above simulants at the same pH than the P-PONbs themselves, a critical control experiment.
Journal ArticleDOI
Self-assembly of polyoxometalates, Pt nanoparticles and metal–organic frameworks into a hybrid material for synergistic hydrogen evolution
Weiwei Guo,Hongjin Lv,Zheyuan Chen,Kevin P. Sullivan,Sarah M. Lauinger,Yingnan Chi,Jordan M. Sumliner,Tianquan Lian,Craig L. Hill +8 more
TL;DR: A polyoxometalate (POM), Pt nanoparticles (NPs) and a metal-organic framework (MOF, NH2-MIL-53) self-assemble into a hybrid material, PNPMOF, that displays synergistic activity for visible-light-driven catalytic hydrogen evolution as discussed by the authors.
