Advancements and perspectives in chemical research: A comprehensive review

Abstract

This review summarizes the relevant literature in chemical research during 2020–2025 and is organized into seven major themes: chemical synthesis, catalysis, materials chemistry, analytical chemistry, computational chemistry, green chemistry, and nanotechnology. This review collates evidence from 20 peer-reviewed publications to highlight evolving trends, novel approaches, and future research avenues. The 12 principles of green chemistry have provided a framework that unites all disciplines to promote sustainability in pharmaceutical synthesis, catalytic processes, and materials development. Important developments encompass photoredox catalysis for environmentally friendly organic transformations, Pickering emulsion catalysis for interfacial reactions, redox chemistry of gold for selective transformations between ionic and radical pathways, and the linking of computational approaches with experimental techniques. Contribution of green chemistry metrics and process intensification towards sustainable pharmaceutical sector: Environmentally friendly design principles are widely used to grow nanotechnology applications. Looking forward, we identify the need for systems-level thinking to integrate initiatives across research spaces; sensitive applications of artificial intelligence towards embedding them within computational chemistry rather than being an independent discipline; circular economy frameworks need development and application in terms of sustainable innovation frameworks; the next generation (which starts in school) needs increased education focusing on themes currently eclipsed. The review showcases significant progress made and the challenges that remain, emphasizing the continuing need for interdisciplinary collaboration toward a sustainable future in chemistry.
