Tetrapods-like Shape Metal-Semiconductor Nanocomposites Synthesis, Characterization and Photo-Catalytic Applications: Au-CdSe Case

Although the physicochemical properties of metal-semiconductor hybrid nanostructures strongly depend on their size, shape, composition, and the spatial distribution of each component, it is increasingly important to find new synthetic routes for these hybrid nanostructures . Many attempts have been made to obtain different structures from metal-semiconductor nanocomposites, in particular Au - CdSe heterostructures (in the case of Nobel metal nanoparticle (NP) chip semiconductor quantum rods). Liang et al. 1 represents a convenient method for synthesizing Au - AgCdSe hybrid nanorods (NR) by depositing a silver (Ag) chip at the end of Au NR as a seed solution.

Metal Oxide Semiconductor Field Effect Transistor (MOSFET) Sensors Based on Changes in Electrostatic Potential These are gates (palladium), silicon oxide insulators (platinum) as shown when polar compounds interact with this metal gate , And three layers that are catalytic metals, also known as silicon semiconductors (gold or gold). The current flowing through the sensor is changed. Electric nose or artificial nose can detect various kinds of chemical substances and can distinguish particles not only for individual but also for fire detection. They work by the fact that smoke is made up of various compounds. These devices consist of dozens of sensors that detect various types of compounds in the air. Let me explain the chemical substances that cause smoke to cause flames.

"Synthesis of Functionalized Ionic Liquids for Nanoparticle Shape Control in Catalytic Reactions" (Lawrence Hill) This project focuses on nanoparticles Synthesis of Ionic Liquids (IL) as Ligands in Chemistry In catalytic nanoparticle studies, conventional ligands with inert hydrocarbon chains and Lewis basic sites effectively control the particle shape, Have been shown to limit aggregation. However, these traditional ligands also bind strongly to the surface of the nanoparticles, reducing the surface area available for the reaction. In contrast, IL loosely binds to the surface of the nanoparticles resulting in greater surface utilization, higher yield, and faster reaction. Presently, 1-butyl-3-methylimidazolium tetrafluoroborate is synthesized in a yield of only 36.9%, and synthesis of 1-3-alkylimidazolium bromide is still in progress.
