“…The size of NPs can be easily con-trolled by the amount of the Pd precursor, and the catalyst showed a high activity in the Suzuki-Miyaura coupling reaction and oxidative homocoupling of arylboronic acids under environmentally friendly conditions [241]. Three-dimensional graphene, which has excellent properties such as ultrahigh surface-to-volume ratio, high porosity, low density, etc., was used for the effective support of Au NPs and PdCo-bimetallic NPs [242,243].…”

Over the past few decades, the use of transition metal nanoparticles (NPs) in catalysis has attracted much attention and their use in C–C bond forming reactions constitutes one of their most important applications. A huge variety of metal NPs, which have showed high catalytic activity for C–C bond forming reactions, have been developed up to now. Many kinds of stabilizers, such as inorganic materials, magnetically recoverable materials, porous materials, organic–inorganic composites, carbon materials, polymers, and surfactants have been utilized to develop metal NPs catalysts. This review classified and outlined the categories of metal NPs by the type of support.

“…Sulfanilic acid is the raw material for the synthesis of many organic dyes by the diazotization reaction to diazonium salt, 4diazoniobenzenesulfonate, followed by the coupling reaction with phenols or aromatic amines. 4-Diazoniobenzenesulfonate is also a zwitterion, a stable precipitate in aqueous medium with a melting point of 104 ° C, used to obtain a large number of azo dyes [7][8][9]. A lab-scale batch reactor for sulfanilic acid synthesis [12,13] Conventional industrial synthesis takes place by so-called baking process at very high temperatures 180-190° C in concentrated sulfuric acid which is also the reaction medium [12].…”

Synthesis of sulfanilic acid was achieved by conventional and green protocols. The starting reagents were the same in both methods. The activation technique of the reaction was different. Conventional synthesis was thermally activated and green synthesis was activated by microwaves. Energophage, chronophage and polluting features constitute important disadvantages of conventional method. The green method performs much better than the conventional procedure: short time, few hazardous wastes and easy experimental setup. The zwitterionic structure of the sulfanilic acid was demonstrated by spectroscopy.

Electron transfer plays a major role in chemical reactions and processes, and this is particularly true of catalysis by nanomaterials. The advent of metal nanoparticle (NP) catalysts, recently including atomically precise nanoclusters (NCs) as parts of nanocatalyst devices has brought increased control of the relationship between NP and NC structures and their catalytic functions. Consequently, the molecular definition of these new nanocatalysts has allowed a better understanding and management of various kinds of electron transfer involved in the catalytic processes. This Minireview brings a chemist's view of several major aspects of electron-transfer functions concerning NPs and NCs in catalytic processes. Particular focus concerns the role of NPs and NCs as electron reservoirs and light-induced antenna in catalytic processes from H 2 generation to more complex reactions and sustainable energy production.
