“…In the same year, Pourjavadi and Habibi synthesized porous carbon material through the carbonization of pomegranate peel waste [168]. The surface of the carbon support was decorated first with Fe 3 O 4 nanoparticles providing magnetically separable catalyst and then with PdNPs via the reduction of Pd(II) with sodium lauryl sulfate (SDS).…”

Among transition metal nanoparticles, palladium nanoparticles (PdNPs) are recognized for their high catalytic activity in a wide range of organic transformations that are of academic and industrial importance. The increased interest in environmental issues has led to the development of various green approaches for the preparation of efficient, low-cost and environmentally sustainable Pd-nanocatalysts. Environmentally friendly solvents, non-toxic reducing reagents, biodegradable capping and stabilizing agents and energy-efficient synthetic methods are the main aspects that have been taken into account for the production of Pd nanoparticles in a green approach. This review provides an overview of the fundamental approaches used for the green synthesis of PdNPs and their catalytic application in sustainable processes as cross-coupling reactions and reductions with particular attention afforded to the recovery and reuse of the palladium nanocatalyst, from 2015 to the present.

“…Pourjavadi and Habibi carbonized pomegranate peel waste to prepare porous carbon (PC); [143] procedure entailed decorating Fe 3 O 4 magnetic nanoparticles on PC using co-precipitation method of iron ions and then, decoration with palladium NPs using sodium dodecylsulfate as surfactant and a reducing agent Remediation of environmental pollutants is an important research subject which can be accomplished by the reduction of organic pollutants, sorption of heavy metals, photocatalytic degradation, etc. Employing biowastes as biosorbents or precursors for the materials used in the degradation of pollutants is a sustainable solution that makes sense economically with numerous environmental advantages.…”

One of the most abundant wastes from all around the world is nutrient resources. Among them, fruits, their extracts, and residues comprise a major portion, which contain many valuable components that get lost during disposal or become burden on the shrinking landfills. These concerns are addressed by seeking sustainable processing methods that would have a minimal environmental impact. The crops contain renewable chemicals which are useful for catalysis, wastewater treatment, or preparation of nanomaterials; there has been an upsurge for the industrial applications of (nano)materials as their environmental and catalytic appliances is a fascinating subject to design cheaper and safer catalytic systems. Due to the excellent chemical properties of the fruit extracts, they have garnered attention as cost-effective catalysts and support materials. This review focuses on the preparation of (nano)materials and their catalytic and environmental applications and highlights the potential appliances and industrial benefits derived from these low-cost renewable and sustainable greener sources thus essentially converting waste into wealth.

“…Only 2% of the Pd was leached giving a TOF leach of 12,500 h −1 . Furthermore, different heterogeneous precursors have been tested in the reaction of iodoaryls (Entries 16, 11, 10, 13, 8, Table 3) and in all the tests the TOF obtained for total Pd was in the order of several hundreds h −1 , but when it was calculated using the amount of leached Pd, it increases to several tens of thousands h −1 [69,[75][76][77][78].…”

A critical review of conclusions about the putative heterogeneous mechanism in the Suzuki-Miyaura coupling by supported Pd solids is reported. In the first section, the turnover frequencies (TOF) of 20 well-established homogeneous catalysts are shown to be in the range 200 to 1,000,000,000 h − 1 . The evidences used to prove a heterogeneous mechanism are discussed and another interpretation is proposed, hypothesizing that only the leached species are responsible for the catalytic reaction, even at ppb levels. Considering more than 40 published catalytic systems for which liquid phase Pd content have been reported, activities have been computed based on leached Pd concentrations and are shown to be in the range TOF 150 to 70,000,000 h − 1 . Such values are compatible with those found for the well-established homogeneous catalysts which questions the validity of the conclusions raised by many papers about the heterogeneous (solid) nature of Suzuki-Miyaura catalysis. Last, a tentative methodology is proposed which involves the rational use of well-known tests (hot-filtration test, mercury test…) to help to discriminate between homogeneous and heterogeneous mechanisms.
