His current research interests are within the realm of innovation and engineering of novel material for mitigating the environmental impact of modern society's activities,focusing on wastewater treatment [2] as well as innovative energy storage and conversion applications. His work is primarily in microporous solids,known as Metal-Organic Frameworks,constructed through the self-assembly of molecular precursors. The permanent porosity of these materials allows for their utilization in a myriad of demanding applications where the chemical space within the pores of such solids can readily be tuned and,further,designed. Of primary interest to his research is to gain a more in-depth understanding of the structure-function relationships pertinent to the nanospace within microporous solids. It is through a better understanding of such fundamental aspects of microporous solids that we can outline blueprint designs to generate novel material tailored to specific applications. Among the applications his group is targeting are wastewater treatment through inventive materials for the capture of heavy metals,organic small molecules,and Perfluorinated compound. Additionally,his research includes designing new material for energy storage (Supercapacitor and Rechargeable battery) and energy conversion through microporous catalysts [3] in electrocatalytic water splitting.
His research accomplishments have been recognized by several awards and honors,including "State Encouragement Award",and "Presidential Excellence Accolade of First Grade" in 2016, [4] Best research article in COMSTECH in 2017, [5] [6] and Selected among world's Top 1% reviewers for Materials Science,awarded by Publons in 2018 and 2019. [7] He also received the Alexander von Humboldt-Georg Forster Experienced Researchers Fellowship in 2019–2023, [8] was selected as a Fellow of the African Academy of Sciences in 2019 [9] and Fellow of the Royal Society of Chemistry in 2021.

A mesoporous material is a nanoporous material containing pores with diameters between 2 and 50 nm,according to IUPAC nomenclature. For comparison,IUPAC defines microporous material as a material having pores smaller than 2 nm in diameter and macroporous material as a material having pores larger than 50 nm in diameter.
Metal–organic frameworks (MOFs) are a class of porous polymers consisting of metal clusters coordinated to organic ligands to form one-,two-,or three-dimensional structures. The organic ligands included are sometimes referred to as "struts" or "linkers",one example being 1,4-benzenedicarboxylic acid (BDC).
Zeolitic imidazolate frameworks (ZIFs) are a class of metal-organic frameworks (MOFs) that are topologically isomorphic with zeolites. ZIF glasses can be synthesized by the melt-quench method,and the first melt-quenched ZIF glass was firstly made and reported by Bennett et al. back in 2015. ZIFs are composed of tetrahedrally-coordinated transition metal ions connected by imidazolate linkers. Since the metal-imidazole-metal angle is similar to the 145°Si-O-Si angle in zeolites,ZIFs have zeolite-like topologies. As of 2010,105 ZIF topologies have been reported in the literature. Due to their robust porosity,resistance to thermal changes,and chemical stability,ZIFs are being investigated for applications such as carbon dioxide capture.

Covalent organic frameworks (COFs) are a class of porous polymers that form two- or three-dimensional structures through reactions between organic precursors resulting in strong,covalent bonds to afford porous,stable,and crystalline materials. COFs emerged as a field from the overarching domain of organic materials as researchers optimized both synthetic control and precursor selection. These improvements to coordination chemistry enabled non-porous and amorphous organic materials such as organic polymers to advance into the construction of porous,crystalline materials with rigid structures that granted exceptional material stability in a wide range of solvents and conditions. Through the development of reticular chemistry,precise synthetic control was achieved and resulted in ordered,nano-porous structures with highly preferential structural orientation and properties which could be synergistically enhanced and amplified. With judicious selection of COF secondary building units (SBUs),or precursors,the final structure could be predetermined,and modified with exceptional control enabling fine-tuning of emergent properties. This level of control facilitates the COF material to be designed,synthesized,and utilized in various applications,many times with metrics on scale or surpassing that of the current state-of-the-art approaches.

In crystallography,a periodic graph or crystal net is a three-dimensional periodic graph,i.e.,a three-dimensional Euclidean graph whose vertices or nodes are points in three-dimensional Euclidean space,and whose edges are line segments connecting pairs of vertices,periodic in three linearly independent axial directions. There is usually an implicit assumption that the set of vertices are uniformly discrete,i.e.,that there is a fixed minimum distance between any two vertices. The vertices may represent positions of atoms or complexes or clusters of atoms such as single-metal ions,molecular building blocks,or secondary building units,while each edge represents a chemical bond or a polymeric ligand.
A two-dimensional polymer (2DP) is a sheet-like monomolecular macromolecule consisting of laterally connected repeat units with end groups along all edges. This recent definition of 2DP is based on Hermann Staudinger's polymer concept from the 1920s. According to this,covalent long chain molecules ("Makromoleküle") do exist and are composed of a sequence of linearly connected repeat units and end groups at both termini.

MIL-53 belongs to the class of metal-organic framework (MOF) materials. The first synthesis and the name was established by the group of Gérard Férey in 2002. The MIL-53 structure consists of inorganic [M-OH] chains,which are connected to four neighboring inorganic chains by therephthalate-based linker molecules. Each metal center is octahedrally coordinated by six oxygen atoms. Four of these oxygen atoms originate from four different carboxylate groups and the remaining two oxygen atoms belong to two different μ-OH moieties,which bridge neighboring metal centers. The resulting framework structure contains one-dimensional diamond-shaped pores. Many research group have investigated the flexibility of the MIL-53 structure. This flexible behavior,during which the pore cross-section changes reversibly,was termed 'breathing.effect' and describes the ability of the MIL-53 framework to respond to external stimuli.
HKUST-1,which is also called MOF-199,is a material in the class of metal-organic frameworks (MOFs). Metal-organic frameworks are crystalline materials,in which metals are linked by ligands to form repeating coordination motives extending in three dimensions. The HKUST-1 framework is built up of dimeric metal units,which are connected by benzene-1,3,5-tricarboxylate linker molecules. The paddlewheel unit is the commonly used structural motif to describe the coordination environment of the metal centers and also called secondary building unit (SBU) of the HKUST-1 structure. The paddlewheel is built up of four benzene-1,3,5-tricarboxylate linkers molecules,which bridge two metal centers. One water molecules is coordinated to each of the two metal centers at the axial position of the paddlewheel unit in the hydrated state,which is usually found if the material is handled in air. After an activation process,these water molecules can be removed and the coordination site at the metal atoms is left unoccupied. This unoccupied coordination site is called coordinatively unsaturated site (CUS) and can be accessed by other molecules.
