Surface-controlled preparation of EuWO4(OH) nanobelts and their hybrid with Au nanoparticles as a novel enzyme-free sensing platform towards hydrogen peroxide

Abstract

EuWO₄(OH) nanobelts were synthesized for the first time via a thiourea-assisted hydrothermal reaction. The nanobelts were further hybridized with Au nanoparticles (NPs) and showed excellent performance in H₂O₂ detection, due to both the enzyme-mimic catalytic properties of Au NPs and the radical responsive –OH groups on the EuWO₄(OH) nanobelt surfaces.
