Boosting the Raman signal on a semiconductor-nanotube membrane for reporting photocatalytic reactions on site†
Abstract
A smooth TiO2 nanotube-based membrane (S-TiNM) is demonstrated to be effective in reducing the Raman-scattering loss in 3D porous structures. Using the photocatalytic reduction of 4-nitrothiophenol as a model, the S-TiNMs show promising potential as sensitive SERS substrates to investigate photocatalytic reactions on site.
