Abstract The development of hydrogen fuel cells is greatly hindered by the unwanted generation of H 2 O 2 at the cathode. A non‐Pt cathode catalyst is now shown to be capable of simultaneously reducing both O 2 and H 2 O 2 , thus rendering H 2 O 2 a useful part of the feed stream. The applicability of this unique catalyst is demonstrated by employing it in a fuel cell running on H 2 /CO and O 2 /H 2 O 2 .
Oxidative damage of DNA by reactive oxygen species (ROS) is responsible for aging and cancer. Although many studies of DNA damage by ROS have been conducted, there have been no reports of the oxidation of RNA components, such as guanosine monophosphate, by metal-based species in water. Here, we report the first case of oxidation of guanosine monophosphate to 8-oxoguanosine monophosphate by a metal-based oxygen bound species, derived from O2 and in water.

Replacing wasteful metal-based reducing agents with H2 is an important goal for green chemistry. For this reason, we outline our design principles for building catalysts that use electrons from hydrogen to activate organohalides for reaction. These designs rely on an electron-withdrawing ligand to support low-valent metal centers, an electron-donating ligand to support oxidative addition, and the capacity for vacant sites to allow substrate docking. We begin by outlining our previous work in this field before describing a new rhodium complex that activates a particularly stubborn organohalide, 2,2-dibromopropane, using electrons from hydrogen. We then react this activated organohalide with styrene to generate a synthetically useful fragment of murraol in an efficient manner.

A rational design of the electron storage catalyst is demonstrated. This design confirms our long-standing confidence in the advantages of water solubility, metal centre as a point for storing electrons from H2, and electron-withdrawing ligand.
