El-Shall is the Mary Eugenia Kapp Chair in Chemistry as well as a professor at Virginia Commonwealth University.[1] Moreover, he also held an appointment as the senior science advisor in the Bureau for the Middle East, Middle East Regional Cooperation (MERC) Program.[2]
Research
El-Shall, along with Wang and others, presented a simple solution synthesis for quantum dots of metal sulfides, featuring chemical reactions between KBH₄, sulfur, and metal salts at room temperature in organic solvents.[3] He also developed a new method of synthesizing polymers by utilizing a laser to vaporize metal targets, adding metal particles to the polymer-formation process.[4] His group developed a microwave-based technique to make uniform nanowires and nanorods of certain semiconductors. The process involved changing the heat time to control the shape evolution from nanoparticles to nanorods, and eventually to extended nanowires.[5] His research group also proposed a microwave-assisted method to deposit metal nanoparticles and reduce graphene oxide simultaneously by utilizing reducing agents.[6]
El-Shall, in collaboration with Abdelsayed and others, reported a photothermal reduction method to obtain reduced graphene oxide (rGO) sheets.[7] His work established the effectivity of hybrid catalysts made using microwave-assisted chemical reduction in catalyzing carbon–carbon coupling (Suzuki, Heck) reactions.[8] In addition, he also demonstrated the utility of Pd/FE3O4/G nanocomposites as catalysts for Suzuki and Heck cross-coupling reactions.[9] Furthermore, he co-designed a synergistic bimetallic metal–organic framework containing copper and cobaltions using benzene tetraamine and benzene tricarboxylic acid.[10]
