Efficient oxidation of benzyl alcohol into benzaldehyde catalyzed by graphene oxide and reduced graphene oxide supported bimetallic Au–Sn catalysts

Abstract

The Au–Sn bimetallic catalysts supported on GO and rGO prepared by two-step immobilization showed the excellent catalytic performance for the selective oxidation of benzyl alcohol to benzaldehyde under moderate conditions.

MOF-Derived ZrO2-Supported Bimetallic Pd–Ni Catalyst for Selective Hydrogenation of 1,3-Butadiene

“…The HAADF-STEM and EDS mapping of the PdNi/UiO-67-CTAB(3)-A500 catalyst are displayed in Figure 2. The HAADF-STEM and EDS mapping of PdNi/UiO-67-CTAB(3)-A500 demonstrated that Pd and Ni elements were highly intermixed and evenly distributed on the support, confirming the formation of Pd-Ni alloys [58,59]. The samples of UiO-67-CTAB(n) and PdNi/UiO-67-CTAB(n)-A500 (n = 0, 3, 8, 13, 18) have been characterized by PXRD.…”

“…The characterization of the catalysts by TE played that PdNi/UiO-67-CTAB(8)-A500 presented the largest average partic PdNi/UiO-67-CTAB(13)-A500 presented the middle average particle size, a PdNi/UiO-67-CTAB(0)-A500, PdNi/UiO-67-CTAB(3)-A500, and PdNi/UiO-67-CTA A500 catalysts presented smaller average particles sizes. The HAADF-STEM an mapping of the PdNi/UiO-67-CTAB(3)-A500 catalyst are displayed in Figure HAADF-STEM and EDS mapping of PdNi/UiO-67-CTAB(3)-A500 demonstrated and Ni elements were highly intermixed and evenly distributed on the support, co ing the formation of Pd-Ni alloys [58,59]. The TEM images and Pd-Ni nanoparticle size distribution histograms of PdNi/UiO-67-CTAB(n)-A500 (n = 0, 3, 8, 13, 18) catalysts are displayed in Figure S1.…”

Engineering Ultrathin Alloy Shell in Au@AuPd Core‐Shell Nanoparticles for Efficient Plasmon‐Driven Photocatalysis

“…The benzaldehyde produced from the selective oxidation of benzyl alcohol is widely used in various industries. [28,29] However, achieving high conversion and selectivity of benzaldehyde requires addressing the challenge of promoting the cleavage of the O─H bond and dehydrogenation processes facilitated by electron transfer in the catalyst and adsorption of reactant. Through precise modulation of the Pd ratio in the dilute Au/Pd alloy NPs, we develop Au@AuPd core-shell NPs, whose ultrathin shell consists of an AuPd alloy with the tuned atomic Pd fraction from 3 at% to 45 at% corresponding to the Pd composition of the shell from 7.2% to 205.4%.…”
