Separation and Recovery of Platinum and Palladium from Spent Petrochemical Catalysts Using Activated Carbon, Analysis of Two Kind of Most Used Catalysts in Petro Chemistry

The goal of this work is the separation and recovery of platinum and palladium from spent catalyst. The recovery consisted of separating the maximum amount of platinum and palladium from catalysts and changing them into usable forms. The petroleum and petrochemical units use Pt and Pd catalyst for reactions such as reforming and hydrogenation. Because these materials contain valuable metals...

Design of Highly Uniform Platinum and Palladium Nanoparticle Decoration on TiO2 Nanotube Arrays: An Efficient Anode to the Electro-Oxidation of Alcohols

We explore electro-catalytic properties of a system consisting of platinum and palladium nanoparticles dispersed over a nanotubular self-organized TiO2 matrix. These electrodes prepared by electroess and microemulsion of palladium and palladium nanoparticles on to TiO2 nanotubes, respectively. Titanium oxide nanotubes were fabricated by anodizing titanium foil in ethylene glycol (EG) fluoride-c...

A Survey of Anticancer Effect of Some Five- and Six-Membered Palladium (II) Complexes (Containing Bidentate Phosphorus Ligands) on Caco-2 Colon Cancer Cell Line

Background and Objectives: Transition metal complexes possess a variety of biological and pharmacological activities, such as antitumor, antimicrobial, anti-inflammatory, anti-diabetic, and free radical scavenging. Many studies have been carried out on platinum-based chemotherapy agents, however, most attention has been paid to non-platinum metal-based agents in order to find different metal comp...

Using the Palladium as core and Platinum as shell for ORR

In this work, electrocatalyst with core-shell structure (Pd as core and Pt as shell on VulcanXC-72R) was synthesis. Not only this structure can reduce the amount of platinum but it also can increase the gas diffusion electrode (GDE) performance in cathode reaction (Oxygen Reduction Reaction or ORR) of polymer electrolyte membrane fuel cell (PEMFC). To this meaning, one series of electrocatalyst...

Conductance of Pd-H Nanojunctions

016802-1 Results of an experimental study of palladium nanojunctions in a hydrogen environment are presented. Two new hydrogen-related atomic configurations are found, which have conductances of 0:5 and 1 quantum unit (2e2=h). Phonon spectrum measurements demonstrate that these configurations are situated between electrodes containing dissolved hydrogen. The crucial differences compared to the ...
