Deep eutectic solvents (DESs) are a group of eco-friendly, low-cost and tuneable that have gained significant attention in recent years due to their remarkable properties including high solubility conductivity, low toxicity easy recovery. DESs also demonstrated outstanding catalytic activity, especially as green alternative traditional catalysts several chemical reactions organic synthesis, biomass conversion pharmaceutical manufacturing, among others. In this review, we explore the potential co-solvents reaction media or diversity reactions, focusing on both homogeneous heterogeneous catalysis electrocatalysis during last quinquenium. The review article is organised three main sections: catalysis, electrocatalysis. each section, most research regarding versatile types synthesis presented discussed. Furthermore, offers insights into future perspectives catalysis.

CeO2 (cerium dioxide or ceria) is a versatile material for industrial catalysis because of its reversible Ce4+/Ce3+ redox pair and tunable oxygen vacancies. Purification air pollutants released from vehicles stationary chemical industries one the imperative catalytic applications CeO2. In this regard, significant efforts have been made to improve properties by precisely controlling its' particle shape. This fascinating shape-controlled strategy can stabilize surface-enriched crystal facets with excellent properties, abundant surface vacancies, enhanced active-site accessibility, high activities. The synergistic effect doping deposition transition metals in improving structure–activity ceria also unraveled pollution control. Thus, review aims summarize elucidate advances field control using ceria-based nanomaterials. adverse effects four types pollutants, namely carbon monoxide, soot particulates, nitrogen oxides, volatile organic compounds, while emphasizing drawbacks challenges associated current technologies were briefly provided. role various doped (Zr, Ti, Mn, Co, Fe, Ni, etc.) deposited (Au, Pt, Pd, Ru, Ag, Cu, well-defined morphologies (rods, cubes, tubes, polyhedra, spheres, fibers, was meticulously discussed. We hope that timely important provide promising strategies rational design advanced catalysts not only but energy-related applications.
