Mohammad Mansoob Khan is a Professor of Inorganic Chemistry at Chemical Sciences, Faculty of Science, Universiti Brunei Darussalam, Brunei Darussalam. He earned his PhD from Aligarh Muslim University, Aligarh, India, in 2002. He has worked in India, Ethiopia, Oman, and South Korea and has established excellence in teaching and novel research. He is teaching various courses at undergraduate and postgraduate levels. He has edited three books and authored two books. He has published about 250 research and review articles. He has addressed several conferences as a Plenary speaker (01 talk), Keynote speaker (10 talks) and delivered Invited talks (15 talks). Additionally, he is associated with several journals as editor, associate editor, reviewer, etc. His expertise is in the cutting-edge area of nanochemistry, nanotechnology, materials sciences, and materials chemistry, especially in the field of inorganic and nanohybrid materials such as the synthesis of noble metal nanoparticles, their nanocomposites, metal oxides (such as TiO2, ZnO, SnO2, CeO2, etc.), and chalcogenides (such as CdS, ZnS, MoS2, etc.), perovskites, MXenes, and their nanocomposites. He is also extensively working on the band gap engineering of semiconductors (such as metal oxides and chalcogenides). The synthesized nanostructured materials are used for heterogeneous photocatalysis, hydrogen production, photoelectrodes, solar cells, sensors, and biological applications such as antibacterial, antifungal, antibiofilm activities, etc.
