“…However, biodiesel production also generates glycerol (≈10 %), which has long been considered a waste byproduct . This surplus, low‐costing, nontoxic, nonflammable, and easy‐to‐handle alcohol could be used as a fuel in solid polymer electrolyte fuel cells (PEMFCs) and solid alkaline membrane fuel cells (SAMFCs) . In comparison to usual organic fuels such as methanol (4.82 kWh L −1 ) and ethanol (6.31 kWh L −1 ), glycerol has an energy density of 6.26 kWh L −1 .…”

Effect of Co‐catalyst on the Selective Electrooxidation of Glycerol over Ruthenium‐based Nanomaterials

et al. 2016

View full text Add to dashboard Cite

Ruthenium‐based Pd and Pt nanoparticles were prepared by mild microwave‐assisted heating and were characterized by X‐ray diffraction and transmission electron microscopy. The activities of these catalysts during the oxidation of glycerol in alkaline media were studied by electrochemical, analytical, and in situ spectroscopy techniques. Changing the noble metal (Pd or Pt) allowed the selectivity of the catalysts to be tailored during the electrooxidation of glycerol. This introduces the possibility of utilizing the catalysts in cogeneration processes for renewable energy sources and also of employing the catalysts to produce value‐added molecules selectively. High‐performance liquid chromatography evidenced that the PtRu material had excellent catalytic activity in the selective oxidation of glycerol to dihydroxyacetone, whereas the PdRu anode favored the production of glycerate.

Glycerol electrooxidation has attracted immense attention due to the economic advantage it could add to biodiesel production. One of the significant challenges for the industrial development of glycerol electrooxidation process is the search for a suitable electrocatalyst that is sustainable, cost effective, and tolerant to carbonaceous species, results in high performance, and is capable of replacing the conventional Pt/C catalyst. We review suitable, sustainable, and inexpensive alternative electrocatalysts with enhanced activity, selectivity, and durability, ensuring the economic viability of the glycerol electrooxidation process. The alternatives discussed here include Pd-based, Au-based, Ni-based, and Ag-based catalysts, as well as the combination of two or three of these metals. Also discussed here are the prospective materials that are yet to be explored for glycerol oxidation but are reported to be bifunctional (being capable of both anodic and cathodic reaction). These include heteroatom-doped metal-free electrocatalysts, which are carbon materials doped with one or two heteroatoms (N, B, S, P, F, I, Br, Cl), and heteroatom-doped nonprecious transition metals. Rational design of these materials can produce electrocatalysts with activity comparable to that of Pt/C catalysts. The takeaway from this review is that it provides an insight into further study and engineering applications on the efficient and cost-effective conversion of glycerol to value-added chemicals.

“…Direct alcohol fuel cells are more attractive amongst other fuel cell types due to their ability to be used in transport and portable electronic devices [1][2][3]. The use of alcohols as fuel is advantageous because alcohols do not require specialised storage as opposed to hydrogen fuel, as well as the high volumetric density of alcohols [1,4]. The types of alcohols used include methanol, ethanol, ethylene glycol and glycerol.…”

Electrochemical Deposition of PdBiSn Catalyst for Glycerol Oxidation in Alkaline Medium

PdBiSn thin film on Au substrate was prepared by means of the electrochemical atomic layer deposition (E-ALD) technique. The morphology and elemental distribution of the catalysts was determined using scanning electron microscope equipped with energy dispersive spectroscopy (EDS) detector. The catalysts contained all the deposited elements distributed evenly on the surface. Electro-oxidation of glycerol was tested in alkaline media using cyclic voltammetry (CV) and chronoamperometry (CA). The activity of the catalysts towards the oxidation of glycerol improved with the addition of Sn and Bi with the binary PdBi catalyst being the most improved.
