Visible light induced electron transfer behavior of a CeO2-loaded HfO2/carbon cluster nanocomposite material

Abstract

a b s t r a c tThe microwave-irradiated calcination of HfOCl 2 /starch complex I under an air atmosphere produced the HfO 2 /carbon cluster composite material which is denoted as Ic. The obtained composite material could decompose methylene blue under the irradiation of light ( > 460 nm). The surface of Ic was loaded with CeO 2 particles to obtain CeO 2 -loaded composite material, which can decompose the aqueous silver nitrate solution and produce O 2 and Ag in the ratio of 1:4.2. Water photo-decomposition experiment was also carried out using Pt-modified composite materials.

Curing behavior, mechanical and thermal properties of epoxy‐CeO2 nanocomposites

“…Moreover, the specific surface area of the nanoparticles is very large, and the specific surface area is found to be greater than 200 m 2 /g after research. [20][21][22][23] There are a large number of highly reactive hydroxyl groups on the surface of nanoparticles. 24,25 These hydroxyl groups will affect the curing reaction of epoxy resin and the degree of curing will improve the mechanical properties of epoxy resin composites.…”
