IR Spectrometers

1.6K
There are two main infrared (IR) spectrophotometers: dispersive IR spectrometers and Fourier transform infrared (FTIR) spectrometers. In a dispersive IR spectrometer, a beam of infrared radiation produced by a hot wire is divided into two parallel equal-intensity beams using mirrors. One beam passes through the sample, while another is a reference beam. The beams then move through the monochromator, which separates the radiations into a continuous spectrum of different frequencies. The...

Inductively Coupled Plasma Atomic Emission Spectroscopy: Principle

957
Inductively coupled plasma (ICP) is the most widely used plasma source in atomic emission spectroscopy (AES), also known as Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). The ICP source, or torch, consists of three concentric quartz tubes with argon gas flowing through them. A spark from a Tesla coil initiates the ionization of argon, generating a high-temperature plasma.
The ions and electrons produced interact with the fluctuating magnetic field created by a water-cooled...

Infrared (IR) Spectroscopy: Overview

2.6K
When electromagnetic radiation passes through a material, atoms or molecules transition from a lower to a higher energy state by absorbing radiation corresponding to the energy difference between the two states. The absorption of infrared (IR) radiation causes transitions between vibrational energy levels in a molecule. Therefore, IR spectroscopy is a useful analytical tool for determining the molecular structure of molecules.
Different compounds display unique properties due to their...

Area of Science:

  • Materials Science
  • Surface Chemistry
  • Spectroscopy

Background:

  • Palladium nanoparticles offer unique catalytic and electronic properties.
  • Attenuated Total Reflection Surface Enhanced Infrared Absorption Spectroscopy (ATR-SEIRAS) is a powerful surface-sensitive technique.
  • Developing robust platforms for ATR-SEIRAS is crucial for surface studies.

Purpose of the Study:

  • To electrodeposit palladium nanoparticles onto indium tin oxide (ITO) modified silicon internal reflection elements.
  • To establish these films as effective platforms for ATR-SEIRAS.
  • To investigate the potential-dependent adsorption of 4-methoxypyridine on palladium.

Main Methods:

  • Electrodeposition of palladium nanoparticles on Si/ITO substrates.
  • Monitoring mid-infrared reflectivity during electrodeposition to identify the percolation threshold.
  • Scanning electron microscopy (SEM) for morphological characterization.
  • Effective Medium Theory (EMT) modeling of interfacial reflectivity.
  • ATR-SEIRAS to study molecular adsorption and orientation.

Main Results:

  • Successfully electrodeposited palladium nanoparticles on Si/ITO, forming excellent ATR-SEIRAS platforms.
  • Identified a distinct reflectivity minimum corresponding to the electronic percolation threshold of Pd islands.
  • EMT modeling qualitatively agreed with experimental ATR-SEIRA spectra, showing dependence on palladium coverage.
  • Observed potential-dependent adsorption of 4-methoxypyridine, including orientation changes and altered π-bonding.

Conclusions:

  • Electrodeposited Pd/Si/ITO serves as a viable platform for ATR-SEIRAS.
  • The study demonstrates a method to control and characterize Pd nanoparticle films.
  • The findings provide insights into the surface chemistry and adsorption behavior of organic molecules on palladium.
