Supported Transition Metal Catalysts for Organic Fine Chemical Synthesis: A Review

Abstract

Transition metal catalysts play an important role for synthesis of industrially and laboratory important organic fine chemicals to control the selectivity, activity and stability. In this review, we focus on mainly transition metal based supported catalyst, mainly oxide supported catalyst for heterogeneous catalytic hydrogenation and oxidation of some synthetically important organic molecules. First we discuss the industrially important catalytic organic synthetic reactions. This is followed by the role of supported metal catalysts in the heterogeneous synthetic catalytic reactions with specific attention to hydrogenation and oxidation of organic molecules. The role of base metals and noble metals in monometallic and bimetallic catalysts are then discussed. Some synthetic routes for preparation of oxide supported metal catalysts are also discussed. Finally, a general discussion of the metal-support interaction (MSI) in oxide supported metal catalysts is made.

“…[12][13][14][15][16][17][18] The combination of functionalized silica supports, also known as molecular modified supports, with metal compounds is providing further applications of supported metal catalysts and with the advancement of methodologies to study the catalysts in action will provide new tools to synthetic chemistry. [1,2,[11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] The study of metal-support interactions has made possible the generation of reusable catalytic materials with great catalytic performance, where the support plays an important role interacting with organic molecules and facilitating their transformation. [19][20][21] Silica-supported metal catalysts are used industrially for a wide variety of reactions, such as (de)hydrogenation and oxidation, the FischerÀ Tropsch synthesis, ammonia synthesis, hydrodenitrogenation, and hydrodesulfurization.…”

Selective Hydrogenation of 5-Acetoxymethylfurfural over Cu-Based Catalysts in a Flow Reactor: Effect of Cu-Al Layered Double Hydroxides Synthesis Conditions on Catalytic Properties

“…In this connection, AMF is an appropriate substitute for HMF [5][6][7][8]. In recent years, increased attention has been paid to the development of none-noble metal catalysts for the synthesis of chemicals [9][10][11][12][13][14][15]. Among them, Cu-based catalysts have shown promising properties in hydrogenation reactions, such as methanol synthesis [16,17], nitroarene reduction [18][19][20], reductive amination of aldehydes or ketones [20,21], selective hydrogenation of formyl group in furanic aldehydes [22][23][24][25] and so on.…”
