The undergraduate student perception of inorganic chem-istry as routine and unimaginative was transformed by adopt-ing few innovative approaches in the pedagogy. This is pri-marily a reﬂection of my experiences in classroom teaching that is presented in this commentary. Fun-oriented, anal-ogy based and pragmatic approach was used to explain sim-ple concepts in inorganic chemistry. Laboratory demonstrations and exposure to understand research articles made the course more interesting. Selective examples of deﬁning classroom moments are presented in this reﬂective commentary. Framing questions in an animated, imaginative and unconventional style made students feel quite challenged and also experience the joy in learning. The introduction of group discussion as an evaluative component enhanced the soft skills of the students. The creative instinct in learning changed students’ perception of inorganic chemistry from an insipid to a highly engaging and captivating subject.

This concise article essentially centres on the growing need to develop eco-friendly materials to sequestrate diverse contaminants from wastewater. The perspective emphasizes the importance of biodegradable, polysaccharide-based materials such as cellulose and chitosan and the advantages of diverse functional groups such as hydroxyl and amine in these biopolymers. Tailoring these biopolymers with non-toxic metal oxides for enhanced removal is also discussed. Carbonization of biomass is another aspect discussed in the article. Batch laboratory studies, with regard to the adsorption capacity, regeneration, and stability of these customized materials are of paramount importance before applying them in the treatment of larger volumes of wastewater. These features will open the doors for chemists and chemical engineers to work together and evaluate the viability of upgradation using customized biopolymers and carbonaceous materials to treat industrial effluents.
