The development of high-efficiency adsorbents for recovering gold from electronic waste has significant economic and environmental benefits. In this work, the efficient and selective adsorbents (MoS 2-TpTa-0.5, MoS 2-TpTa-1.0 and MoS 2-TpTa-1.5) were fabricated by combining TpTa, a COF material obtained by condensing 2,4,6-Triformylphloroglucinol
