This study synthesizes colloidal silver triangular nanoprisms via dual-reduction method. The particle morphology is controlled by changing the silver nitrate and polyvinylpyrrolidone concentrations. The triangular silver and spherical silver colloids are combined with TiO2 powder for methylene blue (MB) photodegradation in visible light. Comparisons between the spherical Ag (S-Ag) and experimental results show that the triangular silver (T-Ag) significantly promotes MB degradation under visible light, which contributes to the surface plasmon resonance effect on the Ag triangular nanoprisms.
