“…3(a, b). The overall thermal behavior of the two materials was similar, however, mass loss was observed for ZIF-9 containing nanofibers only in the range of 120$280 C. This result can be attributed to the removal of DMF and H 2 O contained within the ZIF-9 framework [39]. Additionally, if the thermal treatment temperature exceeded 287 C, ZIF-9 was observed to decompose.…”

The transition from today's fossil-based economy to a sustainable economy based on renewable biomass is driven by the concern of climate change and anticipation of dwindling fossil resources. Although biofuels are the central theme of the transition, biomass resources cannot completely replace petroleum. It is projected that biofuels can only supply up to 30 % of today's transportation fuel market even if all available domestic biomass resources are used for the production of liquid fuels. Therefore, transformation of biomass into high-value-added chemicals is advantageous to secure optimal use of the abundant, but limited, biomass resources from the economical and ecological perspective. Industry is increasingly considering bio-based chemical production as an attractive area for investment. The potential for chemical and polymer production from biomass is substantial. The US Department of Energy recently issued a report which listed 12 chemical building blocks considered as potential building blocks for the future. Organic acids (e.g., succinic, lactic, levulinic acid, etc.) are among the widely spread ''platform-molecules,'' which may be further converted into possibly derivable high-value-added chemicals. The transition from a fossil chemical industry to a renewable chemical industry will likewise depend on our ability to focus research and development efforts on the most promising alternatives. In this chapter, we review the emerging technologies on catalytic conversion of biomass to value-added organic acids in aqueous media.

“…Consistent with the above, the pronounced increase in activity for the reduced Au catalyst, when compared with its calcined analogue, can also be corroborated from the detection of higher quantities of nanoparticulate gold, as confirmed from the shift in the binding energies in the 60 XPS spectra (Figure 3). It was therefore unsurprising to note that only a marginal difference was observed in the catalytic activity of the reduced Pd catalyst, when compared with its calcined counterpart, as only a very small proportion of metallic Pd was detected by XPS (and bic oxidation of vanillyl alcohol, [62][63] although the use of a base was mandatory in these systems. In these studies, [62][63] conversion and selectivity towards vanillin appear promising, however the low substrate to catalyst ratios employed result in inferior TONs at complete conversion.…”

Elucidating Structure–Property Relationships in the Design of Metal Nanoparticle Catalysts for the Activation of Molecular Oxygen

A novel synthetic strategy for the design of metal nanoparticles by extrusion of anionic chloride precursors from a porous copper chlorophosphate framework has been devised for the sustainable aerobic oxidation of vanillyl alcohol (4-hydroxy-3-methoxybenzyl alcohol) to vanillin (4-hydroxy-3-methoxybenzaldehyde) using a one-step, base-free method. The precise nature of the Au, Pt and Pd species has been elucidated for the as-synthesized and thermallyactivated analogues, which exhibit fascinating catalytic properties when subjected to diverse activation environments. By 20 employing a combination of structural and spectroscopic characterization tools, it has been shown that analogous heat treatments have differing effects on extrusion of a particular metal species. The most active catalyst in this series of materials were the extruded Pt nanoparticles that were generated by reduction in H2, which exhibit enhanced catalytic behavior, when compared to its Au or Pd counterparts, for industrially-significant, aerobic oxidation reactions.
