Abstract
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.
