“…Although the number of reports for monometallic supported Pd catalysts is low in comparison with Au and Pt catalysts, there is still ongoing research to improve these catalysts for glycerol oxidation. In general, basic conditions are also required for Pd- and Ag-containing catalysts to obtain high activity for glycerol oxidation as in the case of Au, although small glycerol conversions can be obtained under neutral conditions. , Because of the low number of reports emerged during the last years, both the mono- and bimetallic Pd- and Ag-containing catalysts are summarized in this section with some examples listed in Table . − …”

Glycerol is a highly versatile molecule because of its three hydroxyl groups and can be transformed to a plethora of different value-added fine chemicals and products. It is an important byproduct in biodiesel production and, hence, produced in high amounts, which resulted in a high surplus flooding the market over the last decades. Thus, glycerol is regarded as a potential platform chemical, and many research efforts were devoted to find active catalysts to transform glycerol to various products via different catalytic processes. The selective oxidation reaction is one of the most promising reaction pathways to produce valuable fine chemicals used in the chemical and pharmaceutical industry. This Review describes the recent developments in selective glycerol oxidation to value-added products over heterogeneous catalysts. Particular emphasis is placed not only on newly developed catalysts based on supported noble-metal nanoparticles but also on catalysts containing nonprecious metals. The idea of using cost-efficient non-noble metals for glycerol oxidation is appealing from an economic point of view. Numerous parameters can influence the catalytic performance of the materials, which can be tuned by various synthetic approaches. The reasons for enhancements in activity are critically examined and put into perspective among the various studies. Moreover, during the past decade, many research groups also reported photocatalytic and, more scarcely, electrocatalytic pathways for glycerol oxidation, which are also described in detail herein and have otherwise found little attention in other reviews.

“…It is well-known that oxidation of glycerol and glucose easily generates glyceric acid and lactic acid as monocarboxylic intermediates (selectivity: ∼90%). − However, selective oxidation of glyceric acid to TA is very difficult due to intrinsically poor secondary oxidation selectivity. More importantly, decarboxylation tendency is significantly strong in the presence of noble metal catalysts. − For example, monometallic Pd and Au catalysts display good selectivity of TA (∼80%), but poor activity (TOF < 100 h –1 ) restricts their industrial applications. − Bimetallic alloyed PtM (M: Cu, Pd, Fe, Mn) catalysts show promising performances compared with monometallic ones (TOF: 2300–20 000 h –1 , S = 12–42%). − Therefore, it is clear that, in most cases, bimetallic catalysts outperform monometallic ones in terms of catalytic activity.…”

Rational control of catalytic selectivity still remains a grand challenge in the field of biomass conversion to valueadded chemicals. In this paper, we used PtFe catalyst as an example to understand fundamentals for lattice strain, electronic reconfiguration, reaction kinetics and catalytic selectivity for aqueous conversion biopolyols. Structurally strained face centered tetragonal (fct) PtFe crystals were synthesized and it was confirmed that such unique PtFe nanostructures display intriguing electronic coupling effect and partial charge distribution, as revealed by surface characterization using TEM, XRD and XPS, as well as DFT calculation. Bimetallic PtFe-fct catalysts exhibit a remarkable catalytic activity (TOF: 24 312 h −1 at 65 °C and 1 MPa O 2 ), enhanced selectivity (tartronic acid: 54%) and improved stability for aqueous phase oxidation of biopolyols, in comparison with conventional fcc morphology. Kinetic modeling further indicates that relatively lower oxidation barrier and restrained decarboxylation reaction are key for improving selectivity on PtFe-fct catalysts.
