Preparation and study of the catalytic application in the synthesis of xanthenedione pharmaceuticals of a hybrid nano-system based on copper, zinc and iron nanoparticles

Highly porous copper-supported magnetic nanocatalysts: made of volcanic pumice textured by cellulose and applied for the reduction of nitrobenzene derivatives

“…[4][5][6][7][8][9][10][11] Heterogeneous catalytic composites are modied by various components, such as organic structures, polymers, inorganic particles, biological structures, copper nanoparticles, and palladium nanoparticles, so that the majority of the catalytic sites are available. [12][13][14][15][16][17][18][19][20] In recent years, more attention has been paid to green chemistry due to environmental concerns. 20,21 That is why researchers are constantly trying to design novel natural heterogeneous catalytic systems with a high degree of biocompatibility.…”

Functionalized hybrid magnetic catalytic systems on micro- and nanoscale utilized in organic synthesis and degradation of dyes

“…Also, it acts as a center through which an electron transfers to give the enol (B) form from keto (A). Besides, Ru 3+ and hydrogen bonding advance the Knoevenagel condensation of a carbonyl compound (1) with malononitrile (2). It should be noted that the Ru 3+ and hydroxyl groups of CMCs are active catalytic sites to promote the Michael addition of the reaction intermediates (B and C), as displayed in Fig.…”

“…However, this problem can be alleviated by using appropriate catalysts in the synthetic process. [1][2][3][4] Also, the discharge of dangerous and toxic drugs in water, which has farreaching effects on the aquatic ecosystem and the health of living creatures, has become a major problem. One solution to this issue is to catalytically degrade drugs into low-risk components.…”

Enhanced antimicrobial treatment by a clay-based drug nanocarrier conjugated to a guanidine-rich cell penetrating peptide

“…For this purpose, the same procedure as the above section was performed with this difference that the neat HNTs (0.5 g) were dispersed in the solution of the iron salts, before addition of the NH 3 ·H 2 O solution. 53 …”
