Dramatic acceleration by visible light and mechanism of AuPd@ZIF-8-catalyzed ammonia borane methanolysis for efficient hydrogen production

“…S4 and Table S2 †), as reported previously upon related treatments. 16,26 The high-angle annular dark eld coupling with scan transmission electron microscopy (HAADF-STEM) images were utilized to show the nanostructure of such an alloy and the representative NP. As shown in Fig.…”

“…The signals representing the binding energies of Au 4f and Pd 3d demonstrate that Au(I) and Pd(II) ions are present, which is preceded by the oxidation of the AuPdNPs by air between the time of synthesis and that of measurement. 26 By comparing bimetallic alloys and monometallic NPs, the electronic inuence between Au and Pd is analyzed. Here, the binding energies of Au 4f (83.4 eV and 87.1 eV) of the AuPd alloy undergo a shi to values lower than those of AuNPs (84.0 eV and 87.9 eV) (Table S3 †).…”

“…24 Although rst-row late transition-metal-based nanocatalysts are privileged, 18,[24][25][26] there are also reports using more efficient noble-metal catalysts. 23,27 Recently, the plasmon-induced enhancement of catalytic reactivity has received attention for AB dehydrogenation under visible-light irradiation 25,26 given the excitation of plasmon that accelerates reactions. [26][27][28][29][30] The dissipation of energy proceeds by the scattering of radiative photons or the induction of charge transfer, provoking reaction rate enhancement.…”

Synthesis of rGO supported Cu@FeCo catalyst and catalytic hydrolysis of ammonia borane

“…Various carriers have been widely used to prepare well-dispersed catalysts. 6,[30][31][32][33][34] As we all know, graphene is a special carbon material with single atom thickness with a large surface area and a high density of free electron. As a desirable carrier material, it can make metal NPs to disperse well in absence of surfactant.…”
