The global utilization of hydrogen peroxide, a green oxidant that decomposes in water and oxygen, has gone from 0.5 million tonnes per year three decades ago to 4.5 million tonnes per year in 2014, and is still climbing. With the aim of expanding the utilization of this eminent green chemical across different industrial and civil sectors, the production and use of hydrogen peroxide as a green industrial oxidant is reviewed herein to provide an overview of the explosive growth of its industrial use over the last three decades and of the state of the art in its industrial manufacture, with important details of what determines the viability of the direct production from oxygen and hydrogen compared with the traditional auto-oxidation process.

Transition-metal-catalyzed cross-couplingr eactions are central to many organic synthesis methodologies. Traditionally,P d, Ni, Cu, and Fe catalysts are used to promote these reactions. Recently,m any studies have showedt hat both homogeneous and heterogeneous Au catalysts can be used for activating selective cross-coupling reactions.H ere, an overview of the past studies, current trends, andf uture directions in the field of gold-catalyzed coupling reactions is presented.D esign strategiest oa ccomplish selective homocoupling and cross-coupling reactions under both homogeneous and heterogeneous conditions, computational and ex-perimental mechanistic studies, and their applicationsi nd iverse fields are critically reviewed. Specific topics covered are:o xidant-assisted and oxidant-free reactions;s train-assisted reactions;d ual Au and photoredoxc atalysis;b imetallic synergistic reactions;m echanismso fr eductivee limination processes;e nzyme-mimicking Au chemistry;c lustera nd surface reactions;a nd plasmonic catalysis. In the relevant sections, theoretical and computational studies of Au I /Au III chemistry are discussed and the predictionsf rom the calculationsa re compared with the experimental observations to derive useful design strategies.A.

“…As described before, obstacles such as high cost and rapid catalyst deactivation continue to hinder the industrial applications of currently developed Au-based catalysts [5,34,42]. It is, therefore, of utmost importance to reduce Au loading from 1.0 wt.% to <0.25 wt.% to achieve commercialization.…”

“…Among the numerous metal chlorides [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] and inorganic catalytic materials such as nitrogen-doped carbon [26][27][28], AC-supported g-C 3 N 4 [29], C-doped boron nitride fullerene [30], and 13X zeolite [31], AC-supported AuCl 3 catalysts are considered the most promising materials for acetylene hydrochlorination [32][33][34]. Compared with HgCl 2 for acetylene hydrochlorination, AC-supported AuCl 3 catalysts significantly improve the catalytic activity.…”

“…Compared with HgCl 2 for acetylene hydrochlorination, AC-supported AuCl 3 catalysts significantly improve the catalytic activity. However, the lack of strong oxidants to access the higher Au oxidation state [35] and the instability of Au 3+ species are a great challenge in AC-supported AuCl 3 catalysts for practical application [5,34,36]. For example, although previous work has demonstrated the successful activation of Au/AC catalysts using traditional aqua regia [37], this activation procedure is highly corrosive and hazardous, may cause severe environmental impact, and threatens process safety.…”
