VIP: DNA-Promoted Ultrasmall Pd Nanocrystals on Carbon Nanotubes: Towards Efficient Formic Acid Oxidation
Lian Ying Zhang, Chun Xian Guo, Hongchang Pang, Weihua Hu, Yan Qiao, and Chang Ming Li*
Immobilizing DNA on carbon nanotubes (CNTs) facilitates the growth of uniformly distributed, ultrasmall Pd nanocrystals with good crystalline structure, which results in the frabrication of a unique Pd-DNA@CNTs electrocatalyst. In comparison to Pd-CNTs and commercial Pd/C, the Pd-DNA@CNTs electrocatalyst exhibits a more negative oxidation peak potential, higher catalytic current density, lower charge-transfer resistance, and much better stability towards formic acid oxidation, thus providing great potential as a promising anode catalyst in direct formic acid fuel cells.

Two-in-one: A biological supercapacitor—a combination of an electrochemical capacitor and an enzymatic fuel cell—is presented. Both the capacitor and the biofuel cell are built from nanomaterials, namely, polyaniline/carbon nanotube composites and redox enzyme/gold nanoparticle assemblies. The biosupercapacitor is self-charging, membrane- and mediator-less.

Addressable layers: Core/shell-structured redox-active silica particles have been synthesized in a multistep solid-phase reaction. The viologen shell is electrochemically addressable. A first reduction (see picture) yields particles with a diamagnetic core and a paramagnetic shell (viologen radicals). Such materials are of interest for charge storage and/or functional magnetic materials.

A dynamic catalyst: DFT-based calculations along with in situ X-ray absorption spectroscopy data show that AuPd alloys form unique potential-controlled surface structures during hydrogen adsorption/evolution. Surface segregations take place, with a preference for a gold surface if the surface is free of chemisorbed species, while hydrogen adsorption triggers palladium segregation into the surface.
