Brochantite (Cu4(OH)6SO4) multilayered nanoplates have been synthesized from acidic CuSO4aqueous solution (pH = 3.7–4.5) in the presence of homemade mesoporous ZnO, marking an important distinction from the literature reports in which brochantite synthesis typically occurred in alkaline solution in the presence of hydroxides, for example, NaOH. The as-synthesized brochantitenanoplates further spontaneously organized into flowerlike hierarchical superstructures that exhibited high catalytic activity and good reusability for catalyticwetperoxideoxidation (CWPO) of the azo-dye Congored (CR). The CR degradation efficiency reached 97% under near-neutral, ambient conditions (pH = 6.4, T = 20 °C, p = 1 atm), without elevating the temperature and/or tuning the optimal pH value as is usually done in CWPO reactions for improved degradation efficiency.
