Autor: G. E. Marques, Jorge E. Rodríguez-Páez, Marcio D. Teodoro, J E Ramos-Ibarra, M. Montero-Muñoz, Jose A. H. Coaquira

Publikováno v: Physical chemistry chemical physics : PCCP. 22(14)

A shape-selective preparation method was used to obtain highly crystalline rod-, needle-, nut-, and doughnut-like ZnO morphologies with distinct particle sizes and surface areas. We study the nucleation and growth mechanism of those structures and th

Shape-control of Zinc Oxide nanoparticles: enhancing photocatalytic activity under UV irradiation

Autor: M. Montero-Muñoz, J E Ramos-Ibarra, J A Huamaní-Coaquira, Jorge E. Rodríguez-Páez, Alfonso E. Ramírez

Publikováno v: Journal of Physics: Conference Series. 792:012068

Zinc oxide (ZnO) nanostructures with different sizes and morphologies were synthesized using the Controlled Precipitation Method. It follows a standard process, but with different synthesis and washing solvents to modify the features related to the p
