Abstract

Unprecedented molecular recognition ability governed by a simple bimetallic surface was demonstrated.

ZnAl‐Hydrotalcite‐Supported Au25Nanoclusters as Precatalysts for Chemoselective Hydrogenation of 3‐Nitrostyrene

“…[2] This is acommon problem for most catalysts because they are active for the reduction of the nitro group as well as for the hydrogenation of other unsaturated functional groups (for example,C = C, C = O, and so forth) existing in the same molecule. [4] However,activation of the C = Cbond in styrene was not easy to avoid over ap rolonged reaction period, according to the results of the control experiment.

Refinement of the Microwave‐Assisted Polyol Process for the Low‐Temperature Synthesis of Intermetallic Nanoparticles

“…The phase diagram of the Rh–Pb system shows five room‐temperature phases (Rh 3 Pb 2 , RhPb, Rh 4 Pb 5 , RhPb 2 , RhPb 4 ) . Nanocrystalline Rh–Pb/SiO 2 catalysts (Rh 3 Pb 2 , RhPb, and RhPb 2 ) were prepared by co‐impregnation of silica templates followed by H 2 reduction . By using the microwave‐assisted polyol process RhPb 2 could be obtained (Figure a).…”

Highly Efficient and Chemoselective Reduction of Nitroarenes Using Hybrid Ni@g‐C3N4 as Reusable Catalyst

“…Among others, transition metal catalyzed chemoslective reduction of nitroarenes to their respective amines has been explored using hydrazines, hydrosilanes, molecular hydrogen, sodium borohydride (NaBH 4 ), formic acid etc . Some Ru/ Pd/Pt/ Au/ Rh‐based heterogeneous catalyts have been reported for the reduction of nitroarenes. Recently, Xu et al .…”
