New Ir Bis-Carbonyl Precursor for Water Oxidation Catalysis.

Daria L. Huang, Rodrigo Beltrán-Suito, +6 authors Robert H Crabtree
Inorganic chemistry
2016

This paper introduces Ir(I)(CO)2(pyalc) (pyalc = (2-pyridyl)-2-propanoate) as an atom-efficient precursor for Ir-based homogeneous oxidation catalysis. This compound was chosen to simplify analysis… (More)

Anchoring groups for photocatalytic water oxidation on metal oxide surfaces.

Kelly L. Materna, Robert H Crabtree, Gary W Brudvig
Chemical Society reviews
2017

Surface anchoring groups are needed to attach molecular units to photoanodes for photocatalytic water oxidation. The anchoring group must be hydrolytically stable and oxidation resistant under a… (More)

Poly(ethylene oxide)-poly(butylene oxide)-poly(ethylene oxide)-templated synthesis of mesoporous alumina: effect of triblock copolymer and acid concentration.

Kelly L. Materna, Stacy M Grant, Mietek Jaroniec
ACS applied materials & interfaces
2012

Mesoporous alumina was synthesized via a one-pot self-assembly of aluminum isopropoxide and poly(ethylene oxide)-poly(butylene oxide)-poly(ethylene oxide) triblock copolymer in an acidic ethanol… (More)

Silatranes for binding inorganic complexes to metal oxide surfaces.

Kelly L. Materna, Bradley J. Brennan, Gary W Brudvig
Dalton transactions
2015

A ruthenium complex containing silatrane functional groups has been synthesized and covalently bound to a conductive metal oxide film composed of nanoparticulate ITO (nanoITO). The silatrane-derived… (More)

Surface-Induced Deprotection of THP-Protected Hydroxamic Acids on Titanium Dioxide

Bradley J. Brennan, Christopher Koenigsmann, +5 authors Gary W Brudvig
2016

Hydroxamic acids chelate metals with high affinity and form hydrolytically stable complexes with metal oxides such as TiO2. However, these appealing binding properties can cause problems during the… (More)
