“…Metal catalysts could also benefit from the use of polymer dendrimers as stabilization systems. As an example, poly (amidoamine) (PAMAM) and poly (propylene imine) (PPI) dendrimers were applied to stabilize nanoparticles of Au for the reduction of 4NP [119,120]. The results showed that as the dendrimer concentration increased, the rate constants of catalytic reduction for all of the processes studied declined.…”

The manufacturing, application, and design of chemical processes and products that minimize or remove waste and the use of dangerous and toxic reagents are referred to as green chemistry. Green chemistry is made up of twelve principles, one of which is catalysis. The role of catalysis is to accelerate the reaction by introducing a substance called a catalyst. Because of their high efficiency, productivity, activity, and selectivity, nanocatalysts have recently received many interests. Nanocatalysts are characterized by their high surface area to volume ratio, as well as their nanoscale forms and sizes. One of the significant applications of nanocatalysts is wastewater and wastewater purification. Green and bio-synthesized nanocatalysts could be used efficiently to remove heavy metals, medicinal, organic, and inorganic pollutants from the wastewater systems. This paper reviews nanocatalysts based on noble and magnetic nanocatalysts, as well as metal catalysts supported by organic polymers, and discusses their industrial effluent treatment mechanisms.

“…These are being designed in order to compose task specific metal nano-catalysts. 1,2,3-Triazolyl click dendrimers containing silicon and external pentose groups (Figure 4a) were conceived in order to secure stoichiometric coordination of Au [74] and Pd [75] ions to the internal triazole groups. This set ratio led to the nucleation of smaller metal cores and larger overall active surfaces that were also able to catalyze Suzuki-Miyaura coupling of 4-bromoacetophenone with phenylboronic acid.…”

Radially polymerized dendritic compounds are nowadays an established polymer category next to their linear, branched and cross-linked counterparts. Their uncommon tree-like architecture is characterized by adjustable internal cavities and external groups. They are therefore exceptional absorbents and this attainment of high concentrations into their interior renders them ideal reac-tion media. In this framework they are applied in many environmentally benign implementa-tions. One of the most important among them is water purification though pollutant decomposi-tion. Simple and composite catalysts and photo-catalysts containing dendritic polymers and ap-plied in water remediation will be discussed jointly with some unconventional solutions and fu-ture prospects.

“…One of the eicient methods for the removal of nitro compounds is the reduction of them to the corresponding amines, which are versatile precursors in organic synthesis as well as in the preparation of various compounds such as pharmaceuticals and agrochemicals [8][9][10][11]. In recent years, catalytic hydrogenation of nitroaromatic compounds employing different noble transition metals such as Pd [12][13][14] and Au [15][16][17][18][19][20][21][22] was investigated well. Moreover, cheap alternative metals such as Fe [23][24][25][26][27][28][29][30][31][32], Zn [33][34][35][36][37][38], and Sn [39,40] have been widely used for reduction of nitro group.…”
