Palladium/Stannic Oxide Interfacial Chemistry Promotes Hydrogen Oxidation Reactions in Alkaline Medium

“…The Pd 3d 5/2 and Pd 3d 3/2 spectra are due to the formation of a mixture of nanostructured Pd and PdO, as identified inset. [46] The PdO formation may be traced to the stabilization of the nanostructured Pd by the interaction of the SnO 2 co-catalyst. [47] The deconvolution of Sn 3d is shown in Figure 3c, which gives quartet distinct absorption spectra at binding energies of 484.9, These results reveal that there is a thin Sn film on the SnO 2 (abbreviated herein as Sn@SnO 2 ) in the Pd/SnO 2 /MOFDC matrix structure because the MOFDC further reduces some of the SnO 2 to Sn.…”

Alkaline water-splitting reactions over Pd/Co-MOF-derived carbon obtained via microwave-assisted synthesis

“…The rst step indicates weight loss from room temperature to 134 C, showing loss of water molecules from the pores of the Co-MOF because the Co-MOF has strong adsorption for water molecules. 16 The second weight loss is observed from 372 C to 541 C, ascribable to the decomposition of the BPDC frameworks of the Co-MOF and formation of Co/MOFDC. These results are consistent with the previous report for Co-based MOF using 2,5-dihydroterephthalic acid (DHTP) 16 and corroborate the Raman ( Fig.…”

“…14 which was broken down aer carbonization at high temperature, conrmed with TGA ( Fig. 3 16 The chemically etched Co/MOFDC conrm that most Co and Co 3 O 4 nanoparticles had been removed, giving rise to a pronounced carbon peak at 25.8 for the MOFDC (002) with little trace of peaks of Co/Co 3 O 4 remaining. These results agree with the Raman spectral ( Fig.…”

MOF-Derived Nanocarbons: Synthesis, Properties, and Applications

“…However, carbon materials with these metals have many applications, such as Co@C with a surface area of 195.2 m 2 /g, the prismatic crystals of MOF-74 can be used to make carbon matrix with magnetic properties and cobalt nanoparticles embedded in their surface by a pyrolysis process in situ. [22], the magnetic carbon derived from MOF-74 showed to have great catalytic properties to reduce 4-nitrophenol to 4-aminophenol and is a catalyst that can be re-used. Also, microtubular structures with nano-spheres of cobalt can be obtained from cobalt oxalate microtubes and in situ conversion reaction to MOF (ZIF-67) and self-templates for the tubular structure [23].…”
