Controlling product selectivity in oxidative desulfurization using an electrodeposited iron oxide film

Abstract

Sulfur-containing compounds must be removed from raw fuel oils before use and recently, there has been an effort to identify and optimize a more energy efficient method of oil processing....

Electrodeposition Complexity and the Root Cause of Interfacial Voiding in Solder Joints with Plated Nickel

“…For instance, a research group conducted Raman spectroscopy on electrodeposited iron (Fe) and successfully detected the peak corresponding to FeO x (OH) y in their samples. 28 Given the similarity between Ni and Fe, we initially aimed to detect the peak for NiO x (OH) y in our electrodeposited Ni samples by using Raman spectroscopy. Unfortunately, that attempt was unsuccessful because Raman spectroscopy requires impurity dimensions exceeding 0.5 μm and masses of 0.26 μg or more, 29 which was far more to impurities size and mass associated with our samples.…”

“…Based on our estimate, we can gain insight into the choice of techniques that could provide the sensitivity needed to detect oxygen-containing impurities. For instance, a research group conducted Raman spectroscopy on electrodeposited iron (Fe) and successfully detected the peak corresponding to FeO x (OH) y in their samples . Given the similarity between Ni and Fe, we initially aimed to detect the peak for NiO x (OH) y in our electrodeposited Ni samples by using Raman spectroscopy.…”

A linker selective retention strategy to construct hierarchical porous metal–organic frameworks with high catalytic activity for oxidative desulfurization

“…2 However, the thiophenes, especially benzothiophene (BT), diphenylthiophene (DBT) and its derivatives, are difficult to remove through HDS. 3 Oxidative desulfurization (ODS) has become one of the most common non-hydrodesulfurization technologies in recent years due to its mild reaction conditions, low equipment investment and operating costs, no need of hydrogen and high desulfurization rate. 4 It is worth noting that Lewis acid sites have been widely studied as the catalytic sites or active components for ODS progress.…”
