Photoinduced thermal copper reduction onto gold nanocrystals under potentiostatic control.
We study the photoreduction of adsorbed copper ions onto Au nanoparticles, on an indium tin oxide (ITO) electrode in an aqueous electrochemical cell, as a function of applied voltage and laser intensity. The photocurrent is a nonlinear function of laser intensity and increases sharply with cathodic voltage in the underpotential deposition region. The photoreduction is attributed to laser heatin...
متن کاملSelective Growth of Gold onto Copper Indium Sulfide Selenide Nanoparticles
Hybrid nanostructures are interesting materials for numerous applications in chemistry, physics, and biology, due to their novel properties and multiple functionalities. Here, we present a synthesis of metal–semiconductor hybrid nanostructures composed of nontoxic I-III-VI semiconductor nanoparticles and gold. Copper indium sulfide selenide (CuInSSe) nanocrystals with zinc blende structure and ...
متن کاملTailoring Copper Nanocrystals towards C2 Products in Electrochemical CO2 Reduction.
Favoring the CO2 reduction reaction (CO2RR) over the hydrogen evolution reaction and controlling the selectivity towards multicarbon products are currently major scientific challenges in sustainable energy research. It is known that the morphology of the catalyst can modulate catalytic activity and selectivity, yet this remains a relatively underexplored area in electrochemical CO2 reduction. H...
متن کاملPreparation of copper sphere segment void templates for 1 electrochemical SERS and their use to study the interaction of amino 2 acids with copper under potentiostatic control . 3
11 We describe a simple method to prepare nanostructured copper electrodes based on 12 electrodeposition of copper through a polystyrene nanosphere template to produce a copper sphere 13 segment void (SSV) structure. We show that the SSV copper electrodes give a large SER 14 enhancement under potentiostatic control and we use the SSV copper electrodes to study the 15 adsorption of aromatic and ...
متن کاملPOLAROGRAPHIC AND POTENTIOSTATIC REDUCTION OF CARBODIIMIDES: A MECHANISTIC STUDY
The polarographic reduction of aromatic carbodiimides in anhydrous aprotic solvents goes through a carbene intermediate by a diffusion controlled process in two one-electron steps. The first step is the rate-determining step and converts the carbodiirnide to a radical anion (6) that reduces further by a fast one-electron step to a carbene dianion intermediate (7). This abstracts an oxygen, ...
