“…Examples of this approach are: the electrodeposition of NPs from a solution containing the metal ion, either onto the bare support electrode [74][75][76][77][78][79][80][81][82] or onto the support electrode modified with a polymer film; [78,[83][84][85][86] electroless deposition; [77,87,88] and vacuum evaporation. The coupling of electrodeposition experiments with other characterization techniques, such as ex situ [95][96][97] and in situ TEM, [98,99] as well as small-angle X-ray scattering (SAXS) [100] has provided valuable insights into the early stage of NP formation, which may ultimately lead to improved electrodeposition procedures.

Metal nanoparticles (NPs) find widespread application as a result of their unique physical and chemical properties. NPs have generated considerable interest in catalysis and electrocatalysis, where they provide a high surface area to mass ratio and can be tailored to promote particular reaction pathways. The activity of NPs can be analyzed especially well using electrochemistry, which probes interfacial chemistry directly. In this Review, we discuss key issues related to the electrochemistry of NPs. We highlight model studies that demonstrate exceptional control over the NP shape and size, or mass-transport conditions, which can provide key insights into the behavior of ensembles of NPs. Particular focus is on the challenge of ultimately measuring reactions at individual NPs, and relating the response to their structure, which is leading to imaginative experiments that have an impact on electrochemistry in general as well as broader surface and colloid science.

“…An in situ study of Ag nanoparticles forming on an HOPG electrode in an electrochemical cell was presented by Ustarroz et al [327] The electrode formed one of the windows of the transmission cell. SAXS patterns were collected as a function of time while the electrochemical potential was pulsed to induce nanoparticle formation and subsequent growth.…”

This article provides, in tutorial style, a review of X-ray scattering methods commonly used to characterise nanoparticles and gives numerous case studies of basic science and industrial applications right up to the present. It is divided into two major sections, broadly covering Xray diffraction and small-angle X-ray scattering. Each section begins with a brief introduction to the technique and the information that can be obtained by using it, followed by a discussion on experimental considerations, with a particular focus on nanoparticle characterisation. The techniques and analysis methods are demonstrated by way of examples of a wide variety of nanoparticle materials and synthesis methods. Recent advances in related techniques such as anomalous scattering and pair distribution function analysis are also described and discussed.

“…[89][90][91][92][93] Die Elektroabscheidung ist eindeutig die gängigste dieser Methoden, da sie den elektrischen Kontakt zwischen dem NP und dem Substrat sicherstellt und man über steuerbare Parameter wie Abscheidungspotential oder Abscheidungsstrom, Zeit, Temperatur und Elektrolytzusammensetzung [74,75,94] die Grçßen-, Form-sowie räumliche Verteilung der elektroabgeschiedenen NPs beeinflussen kann. Die Kombination von Elektroabscheidungsexperimenten mit anderen Charakterisierungstechniken wie Exsitu-TEM [95][96][97] und In-situ-TEM [98,99] sowie Kleinwinkelrçntgenstreuung (SAXS) [100] hat wertvolle Einblicke in das Frühstadium der NP-Bildung geliefert, die für die Verbesserung der Protokolle der Elektroabscheidung von Nutzen sein kçnnten.…”

Metall‐Nanopartikel (NPs) haben aufgrund ihrer einzigartigen physikalischen und chemischen Eigenschaften ein großes Anwendungspotential. Für die Katalyse und Elektrokatalyse sind NPs vor allem wegen ihres großen Oberfläche‐Masse‐Verhältnisses und ihrer möglichen zielgerichteten Anpassung für bestimmte Reaktionspfade von Interesse. Die Aktivität von NPs kann insbesondere elektrochemisch, durch die direkte Analyse der Grenzflächenchemie, erforscht werden. In diesem Aufsatz diskutieren wir Aspekte der Elektrochemie von NPs. Wir stellen Modelluntersuchungen vor, bei denen die Form und Größe der NPs außerordentlich genau kontrolliert werden konnten bzw. deren Stofftransportbedingungen wichtige Einblicke in das Verhalten von NP‐Ensembles geben. Besondere Schwerpunkte bilden die Messung von Reaktionen an Einzel‐NPs und die Beziehung zwischen dem Signal eines Einzel‐NP und seiner Struktur. Dafür wurden innovative Experimente entwickelt, die über die Elektrochemie hinaus auch für die breitere Oberflächen‐ und Kolloidwissenschaft von Interesse sind.
