Outline of Final Research Achievements

In this research, 1) Synthesis of highly crystalline transparent conducting oxide (ITO, AZO, GZO, IZO) and BCNO nanoparticles by low pressure spray pyrolysis 2) Droplet generation and nanoparticle formation in low-pressure spray pyrolysis, 3) Pt/WO3 nanocatalysts for efficient pollutant degradation using visible light irradiation, 4) Dispersion of TiO2 nanoparticles with a dual-axis beads-mill 5) Synthesis of a colorless suspension using surface modified TiO2 nanoparticles, 6)Synthesis of spherical macroporous WO3 particles via spray pyrolysis and their high photocatalytic performance, 7) Ultrahigh oxygen reduction activity of Pt/nitrogen-doped porous carbon microspheres prepared via spray-drying has been investigated. In all researches, effects of process parameter and particle performance such as crystal structure and purity on the material characterization were evaluated.
