原始摘要(英文原文)· Original abstract
A reductive nanospiked covalent organic framework (ETTA-TDA-COF) was developed for efficient gold recovery (828.08 mg g-1) and tri-modal sensing. Rapid in situ reduction of Au3+ to Au0 triggers changes in color, surface-enhanced Raman scattering (SERS), and Rayleigh scattering, showing excellent linearity with gold concentrations.
