Palladium recovery from acidic solution with phenanthroline-based covalent organic polymers as adsorbents for efficient heterogeneous catalysis

Abstract

Highly efficient and selective recovery of Pd(II) from high-level liquid waste (HLLW) was realized by new phenanthroline-based organic polymers for subsequent heterogeneous catalysis of Suzuki-Miyaura cross-coupling reactions.

Emerging trends in the development and applications of triazine-based covalent organic polymers: a comprehensive review

“…9). 161 From N 2 adsorption isotherms, the BET surface area was found to be 12.6 m 2 g −1 for COP-1 and 13.7 m 2 g −1 for COP-2, suggesting their non-porous structure. The synthesized polymers were then employed as adsorbents for the removal of Pd( ii ) from acidic solution.…”

Separation of Palladium by an Imine-Linked Cu(I)-Organic Framework

“…Porous materials such as activated carbon, zeolite, metal–organic frameworks (MOFs), covalent organic frameworks (COFs), and porous organic polymers (POPs) have already been explored to recover Pd­(II). − However, a portion of them suffer from poor stability and low adsorption capacity and selectivity, which hindered their development. Therefore, the development of new Pd­(II) adsorbents is urgent.…”
