Nanoporous gold (NPG) is characterized by a bicontinuous network of nanometer-sized
metallic struts and interconnected pores formed spontaneously by oxidative dissolution of …

In situ/operando surface enhanced infrared and Raman spectroscopies are widely
employed in electrocatalysis research to extract mechanistic information and establish …

Although surfaces or, more precisely, the surface atomic and electronic structure, determine
the way materials interact with their environment, the influence of surface chemistry on the …

CO2 reduction in aqueous electrolytes suffers efficiency losses because of the simultaneous
reduction of water to H2. We combine in situ surface-enhanced IR absorption spectroscopy …

In this work, we have designed and synthesized nickel-laden dendritic plasmonic
colloidosomes of Au (black gold-Ni). The photocatalytic CO2 hydrogenation activities of …

Although actuation in biological systems is exclusively powered by chemical energy, this
concept has not been realized in man-made actuator technologies, as these rely on …

Nanostructured materials are governed by their surface chemical properties. This is
strikingly reflected by np-Au. This material can be generated by corrosion of bulk Ag–Au …

Nanoporous gold (np-Au), a three-dimensional nanoporous bulk material, is made by
selective corrosion of Ag from Ag–Au alloys, a technique already applied by the pre …

The selectivity and activity of the carbon dioxide reduction (CO2R) reaction are sensitive
functions of the electrolyte cation. By measuring the vibrational Stark shift of in situ …

The unique properties of gold especially in low temperature CO oxidation have been
ascribed to a combination of various effects. In particular, particle sizes below a few …
