Reductive degradation and discoloration of a sample mixture of 4-nitrophenol and four different dyes in water catalyzed by Ag@TPHH-COF. Conditions of volume and concentration: 4-NP (10 mL, 5 × 10⁻⁴ mol L⁻¹), RhB (10 mL, 5 × 10⁻⁵ mol L⁻¹), MB (10 mL, 1 × 10⁻⁴ mol L⁻¹), MO (10 mL, 2.5 × 10⁻⁴ mol L⁻¹), and CR (10 mL, 5 × 10⁻⁴ mol L⁻¹); catalyst mass = 5 mg); NaBH₄ = 0.5 g.
