We present a new type of nanoporous hydroquinone/catechol formaldehyde resin synthesized by a one‐pot route, with a surface area of up to 1 112 m 2 · g −1 . The resins show highly efficient reactive adsorption for silver/gold (silver adsorbance up to 2.43 g · g −1 ) and excellent selectivity for gold ( K d is as high as 1 914 090 mL · g −1 ). The first‐used resins can be regenerated with NaHSO 3 , and the gold capacities of the recycled PCFR and PHFR reach 44 and 78% of their first loading capacities, respectively.
