“…The positive value of Δ H indicates that the adsorption process is an endothermic process. 48 The positive Δ S and negative Δ G values indicate the spontaneous process of uranium adsorption on m-CNTs@H-PDA-AO and the specific affinity of m-CNTs@H-PDA-AO toward uranium in aqueous solutions.…”

“…Its high reusability without significant efficiency losses and ease of recovery by magnetic separation render it a promising method for sustainable catalysis. In a similar approach by their working group, Wu et al also demonstrated the recovery of Pd(II) via functionalized magnetic particles for a Suzuki-Miyaura cross-coupling reaction between bromobenzene and 4-formylphenylboronic acid with conversion efficiencies of up to 99% [29].…”

The recycling of catalysts has emerged as a key solution to address environmental pollution and the scarcity of natural resources. This dynamic is further reinforced by the growing industrial demand for catalysts and the urgent need to transition to more sustainable production methods. In the context of chemical transformations, the direct reuse of recycled catalysts for chemical applications in particular represents an elegant route towards greener syntheses. In this article, we review recent advancements in the recycling of homogeneous and heterogeneous catalysts since 2020, emphasizing the utilization of waste-derived catalysts for chemical reactions. In particular, we consider three primary sources of waste: electronic waste, spent lithium-ion batteries, and industrial wastewater. For each of these waste streams, different extraction methods are explored for their effectiveness in obtaining catalysts suitable for a broad spectrum of chemical reactions. These presented studies emphasize the potential of recycled catalysts to contribute to a sustainable and waste-efficient future.

“…Adsorption is becoming increasingly significant among these methods owing to its notable efficacy, environmentally sustainable nature, and applicability to solutions with low amounts of noble metals. Adsorption has been shown in prior studies to be a selective method for recovering Pt(IV) or Pd(II) from various media. − An instance of such investigation can be found in the research conducted by Nastasovic et al, wherein they employed suspension copolymerization to produce ethylenediamine-modified macroporous poly(glycidyl methacrylate-ethylene glycol dimethacrylate) (PGME) to adsorb noble metals . However, few studies have investigated the use of PGMA microspheres for the recovery of Pt(IV) and Pd(II), and the adsorption rates and capabilities in these studies have not been highlighted.…”

The present investigation described the application of high-capacity amino-group-functionalized polyglycidyl methacrylate monodispersed microspheres (PGMA-N) in the adsorption of Pt(IV) and Pd(II) ions from simulated wastewaters. The adsorption capacities of Pt(IV) and Pd(II) on PGMA-N were determined to be 3.93 and 4.99 mmol•g −1 , respectively, at 298 K and pH ∼ 4. These capacities are greater than those reported for other adsorbents in the literature. Rapid adsorption kinetics were observed for Pt(IV) and Pd(II) on PGMA-N; equilibrium was reached within 15 min. Co 2+ , Cu 2+ , Ni 2+ , Fe 3+ , Al 3+ , and Cr 3+ were utilized as representatives for competitive adsorption of metal ions, and the good separation selectivity of PGMA-N was observed for Pt(IV) and Pd(II) at pH 1−3. The pH range in which the adsorbent demonstrated optimal selectivity was extended to 1−6 with the addition of EDTA. The −NH 2 , −NH− functional groups on PGMA-N form stable, five-membered chelate rings through synergistic coordination with Pt(IV) or Pd(II), as determined by zeta potential, pH titration, XRD, FTIR, and XPS analysis.
