His research includes the study of redox catalytic cycles, green syntheses, heterogeneous catalysis and characterization of systems using structural, crystallographic, surface, electrochemical, luminescence, microscopic and EPR techniques.
He studied photochemistry and the electron and energy transfer between rare earth and actinide ions in zeolites.
His research indicated that selective placement of certain inorganic ions in zeolite molecular sieves can be used to control the energy transfer efficiencies in various displays and luminescence devices.
His research group found that under specific conditions, the incorporation of manganese cubane clusters in Nafion membranes along with the illumination with light, led to water oxidation in an aqueous solution of sodium chloride and seawater.
[13] Suib used the mesoporous copper sulfide material in a visible light driven catalytic process for the transformation of amines into imines.
[15] In the early 2010s, Suib studied the generation of crystalline, thermally controlled monomodal pore size mesoporous materials.
He discussed the conditions needed for the generation of mesoporous materials, such as inverse milcelles, elimination of solvent effects and the controlled condensation of inorganic frameworks.
According to Suib, manipulating the nanoparticle size can tune the mesopores, and this phenomenon can lead to the development of multiple phases of the same metal oxide and can also aid in the synthesis of materials having different structures and thermal stabilities.
[18] Suib synthesized copper aluminum mixed oxide catalyst, as a green approach for conducting one pot synthesis of imines.
The synthesized catalysts, along with proving to be efficient in the direct amine formation process under solvent free conditions, also exhibited high stability and recyclability.
By analyzing pyridine adsorption results, Suib found that an increased number of Lewis acidic sites contributed to an enhanced catalytic activity.
