“…Before figuring out the structure of the chitin supported nano-metal catalysts, we directly used these catalysts for catalytic chemical reactions. Usually, it is difficult for aromatic molecules with reducible C=C or NO 2 groups to selectively hydrogenate only C=C or NO 2 groups [ 3 , 4 , 6 ]; for example, the aralkyl products, which play important roles in large chemical production, petroleum, cosmetic, organic intermediates, material chemistry, medicinal chemistry, etc. Herein, first of all, the aim of selectively hydrogenating only C=C was attempted, and the 4-nitrostyrene was used as the model substrate to evaluate the catalytic activity of these different chitin supported catalysts.…”

“…It is also very important to convert nitroalkenes into aminoalkene compounds, and the aminoalkene compounds are of great significance in the synthesis of pharmaceutical intermediates, pesticides, natural products, etc. [ 6 , 8 ]. Further, we also attempted the Pt-Ni/Chitin catalyst for selective hydrogenation of NO 2 to NH 2 with the model substrate of 4-nitrostyrene.…”

“…However, the ability of aromatic molecules with reducible functional groups (such as C=C, NO 2 , C=O, etc.) to be activated or reduced is different [ 5 , 6 ]. How to accurately reduce the appointed groups is still a challenge.…”

The hydrogenation products of aromatic molecules with reducible groups (such as C=C, NO2, C=O, etc.) are relatively critical intermediate compounds in fine chemicals, but how to accurately reduce only specific groups is still challenging. In this work, a bimetallic Pt-Ni/Chitin catalyst was prepared for the first time by using renewable biomass resource chitin as support. As the carrier, the chitin was constructed into porous nanofibrous microspheres through the sol-gel strategy, which was favorable for the adhesion of nano-metals and the exchange of reactive substances due to its large surface area, porous structure, and rich functional groups. Then the Pt-Ni/Chitin catalyst was applied to selective hydrogenation with the model substrate of 4-nitrostyrene. As the highly dispersed Pt-Ni NPs with abundant exposed active sites and the synergistic effect of bimetals, the Pt-Ni/Chitin catalyst could efficiently and selectively hydrogenate only NO2 or C=C with yields of ~99% and TOF of 660 h−1, as well as good stability. This utilization of biomass resources to build catalyst materials would be important for the green and sustainable chemistry.

“…Indeed, the AuAg wNRs system is competitive in the selective reduction of 4-aminostyrene to aminostyrene with more complex heterostructurated systems such as 1) Cu NPs deposited on carbon quantum dots (CDs) that act as photocatalyst in this reaction under visible light; [48] 2) Cu 3 P-CDs-Cu multicomponent photocatalytic system, which achieves a high selectivity in the reduction of 4-nitrostyrene to 4-aminostyrene in short times; [49] or 3) platinum clusters deposited on Bi 2 MoO 6 nanosheet surfaces that produce a 100% selectivity for this reduction and a complete conversion in the presence of visible light.

Alloyed AuAg wavy nanorods (wNRs) of %24.0 nm length and 3.5 nm width are formed by the mild decomposition of the organometallic complex [Au 2 Ag 2 (C 6 F 5 ) 4 (OEt 2 ) 2 ] n in tetrahydrofuran (THF) in the presence of oleic acid. Ligand exchange with L-glutathione (GSH) or poly(ethylene glycol) methyl ether thiol (PEG-SH) leads to water-soluble nanostructures. These AuAg wNRs display tunable size-dependent longitudinal localized surface plasmon resonance (l-LSPR) broad absorptions beyond 750 nm in the near-infrared (NIR) I and II regions. These intense plasmonic absorptions lead to interesting photothermal, catalytic, and photocatalytic properties, including the catalytic reduction of 4-nitrophenol, the photocatalytic reduction of 4-nitrostyrene, or the photocatalytic dehydrogenation of ammonia borane for H 2 release.

“…Catalytic transfer hydrogenation is an essential process for organic transformations. So far, most transfer hydrogenation catalysts are homogeneous and rely on noble metals, 32,33 like palladium (Pd), 34 ruthenium (Ru), 35 iridium (Ir), 36 platinum (Pt) 37 and rhodium (Rh). 38 Obviously, the practical applications of platinum catalysts are limited by their scarcity, high price and low biological compatibility.…”
