Catalytic activities of sputtered p-type Cu2O electrode in connection with TiO2 thin film for dye degradation

Wu K.R., Hung C.H., Yeh C.W., Sun J.C., Hsu C.J., National Kaohsiung Marine University, TW

In this study, a p/n-type photoelectrocatalytic (PEC) cell was used to enhance the photocatalytic (PC) and PEC activities towards the degradation of methylene blue (MB) solution under ultraviolet (UV) irradiation. The PEC cell consists of [...]

Novel supported catalytic materials based on multiwalls carbon nanotubes

Koltypin Y., Savilov S.V., Gedanken A., Landau M.V., Bar-Ilan University, IL

We present a method that allows proper control of the nanoscale curvature of the external surface in multiwall carbon nanotubes (MWCNT) and shown its effect on the properties of Ni/MWCNT catalyst. After removal of residual [...]
