Pd, Rh and Ru nanohybrid-catalyzed tetramethyldisiloxane hydrolysis for H₂ generation, nitrophenol reduction and Suzuki–Miyaura cross-coupling

Abstract

The hydrolysis of tetramethyldisiloxane, which is a silicone industrial refuse, provides a convenient method to generates H2 on demand. Herein, the highly selective and efficient 2D graphene-like carbon nanosheets (GCN)...

The Fast Formation of a Highly Active Homogeneous Catalytic System upon the Soft Leaching of Pd Species from a Heterogeneous Pd/C Precursor

“…Transition metal catalysts play an important role in organic synthesis, polymer science, the production of biologically active compounds, and industry developments [1][2][3]. The synthesis and modification of monometallic nanocatalysts [4][5][6][7][8][9][10][11], bimetallic nanocatalysts [12][13][14][15], and mixed metal-nonmetallic nanocatalysts [16][17][18] are actively investigated in recent years. In particular, heterogeneous carbon-supported metal nanoparticle catalysts (M/C) have been applied in the fine chemical industry [19], energy research [20], and metal-catalyzed reactions in organic synthesis [21][22][23].…”

Blue-LED activated photocatalytic hydrogenation of nitroarenes with Cu2O/CuO heterojunctions

“…One advantage of using NaBH 4 is that it allows for hydrogenation to occur in aqueous media and eliminates the need for high-pressure equipment. 7 Additionally, this method can utilize more abundant and cost-effective metals or metal oxides as catalysts, 8,9 with copper and copper oxide being among the most effective catalysts. 10,11 Efforts to develop catalytic processes that are more sustainable and cost-effective are essential from both economic and environmental standpoints.…”

“On–off” switch for H2 and O2 generation from HCOOH resp. H2O2

“…The exploration of efficient and safe production, storage, and transportation (especially in long term) of H 2 , an ultra‐low density and awfully low‐boiling point gas, 11–15 is a serious challenge 16–20 . Consequently, numerous inorganic and organic compounds have been proposed as hydrogen carriers, such as methanol, 21 ammonia, 22,23 methane, 24 ammonia borane, 3,25–29 hydrazine hydrate, 30 dimethylaminoborane, 31 sodium borohydride, 3,32–37 tetrahydroxydi‐boron, 38–41 tetramethyldisiloxane, 42 hydrazine borane, 43 and formic acid (FA) 44–46 . Among them, FA, the main product of biomass manufacture by hydrolysis or oxidation of cellulose with high yields, 47–50 has become one of the most attractive hydrogen carriers due to its excellent hydrogen content (4.4 wt%), high volumetric hydrogen storage density of 53 g/L, nontoxicity, ease of portability, regeneration from CO 2 hydrogenation, and liquid stability at room temperature.…”
