Preparation of Hollow Nanostructures via Various Methods and Their Applications

Abstract

The hollow nanomaterial is a unique material to be developed because of its characteristics, especially the surface area where it has more surfaces than other materials. In general, hollow nanomaterials could be synthesized using hard-templated, soft-templated, self-templated, template-free and simple methods. In this chance, the catalyst preparation focused on using a simple method to study its activity on the dyes photodegradation reaction, deNOx reaction, carbon dioxides utilization, and photoconversion of chemical compounds. The characterization is emphasized on Scanning electron and Transmission electron Microscopes were used to identify its structure and characteristics. Furthermore, the analysis of UV-Vis spectrophotometer and HPLC is done to point out its activity on the photodegradation of dyes, deNOx reaction, and photoconversion of cellulose and carbon dioxides utilization.

Exploring Reliable and Efficient Plasmonic Nanopatterning for Surface- and Tip-Enhanced Raman Spectroscopies

“…(ii) Another mechanism is oxide diffusion at the interface (Kirkendall effect [134]). The different diffusion rates of metals and oxides produces a disequilibrium of the material flow that is compensated with the inter-diffusion of vacancies; the condensation of excess vacancies can give rise to void formation (Kirkendall voids), which leads to the formation of nanopores [135]. Nevertheless, since the Kirkendall effect cannot be activated unless the material is exposed to an elevated temperature, the authors of ref.…”
