Microalgae-derived Co₃O₄ nanomaterials for catalytic CO oxidation

Abstract

Sustainable nanosized Co3O4 catalysts, derived from microalgae extracts and post-synthesis treatments, were employed for oxidative CO removal.

Green Synthesis of Nanoparticles Containing Zinc Complexes and Their Incorporation in Topical Creams with Antimicrobial Properties

“…Different techniques were used to synthesize nanoparticles containing metals that can be grouped into physical methods, chemical methods and biological methods. Many species of plants, algae, fungi, bacteria and viruses were used to synthesize inorganic nanoparticles like silver, gold, copper, CuO, TiO2 and ZnO [9][10][11][12][13][14][15][16]. The green synthesis using different perennial plant species, available in large quantities, is a simple and cost-effective approach that is preferred to the chemical methods since these ones usually are more laborious, have higher production costs and might generate hazardous by-products, with adverse effects in the medical applications [17].…”
