Title: Innovations of Khalid Soliman Khalil Khairou

Introduction

Khalid Soliman Khalil Khairou is a notable inventor based in Makkah, Saudi Arabia. He has made significant contributions to the field of chemistry, particularly in the development of catalysts and photochromic compounds. With a total of three patents to his name, his work showcases innovative approaches to chemical synthesis and catalysis.

Latest Patents

One of Khalid's latest patents is a metal oxide supported palladium catalyst for hydrocarbon oxidation. This catalyst comprises a β-BiO/BiSnO hetero-junction support and palladium, synthesized using a sol-gel technique to create a nanocrystalline structure. In the presence of fluorene, an oxidant, and ultraviolet irradiation, this catalyst effectively converts hydrocarbons into a mixture of fluorenol and fluorenone oxidation products. The close proximity of the β-BiO and BiSnO phases in the catalyst is believed to enhance charge separation and catalytic activity. Additionally, an indirect chemical probe method utilizing active species scavengers has revealed that the photo-oxidation mechanism operates through holes and superoxide radical (O.) moieties.

Another significant patent involves the synthesis of photochromic tetrahydroindolizines (THIs) that feature dihydroisoquinoline derivatives as heterocyclic bases and central fluorene groups. Khalid has explored various chemical and photochemical pathways for synthesizing these compounds. He has also provided three alternative pathways for creating photochromic THI-based pyridazinopyrrolo[1,2-b]isoquinolines through in situ trapping with hydrazine hydrate. High product yields have been achieved using different Sonogashira-mediated coupling reactions. The photochromic and kinetic properties of the synthesized systems have been detected using low temperature multichannel UV-vis and flash photolysis techniques.
