Topic Information

Dear Colleagues,

We are pleased to invite you, along with the members of your research group, to contribute to the forthcoming MDPI Topic, entitled “Catalysis for Sustainable Chemistry and Energy, 2nd Volume”. This Topic is a continuation of our previous successful publication, "Catalysis for Sustainable Chemistry and Energy".

This volume is related to the design and/or the development of catalysts which can minimize the adverse environmental impacts, such as greenhouse gas emissions, and avoid, simultaneously, the use and the generation of by-products with toxic and hazardous properties. Such aims can be achieved by means of tuning the chemical structure and composition of catalytic materials, which may also occur at an atomic and/or molecular scale, in a manner to enhance not only the reactants conversion but also their selectivity towards the desired products.

Papers and review papers dealing with all types of both homogeneous and heterogeneous catalysis, including organocatalysis, photocatalysis, electrocatalysis, environmental catalysis, biocatalysis/enzymes and nanostructured catalysis to promote selective conversions, fall within the scope of this Topic Issue.

Novel reactor or photoreactor configurations, such as catalytic reactors that combine the reaction and separation steps, or design and/or development of (photo)reactors for process intensification, such as microreactors membrane-based reactors and reactors using structured catalysts, also fall within the scope of this publication.

The membrane electrode assembly (MEA) encompassing the polymer electrolyte membrane (PEM) and catalyst layers are the key components in Polymer Electrolyte Membrane Fuel Cells (PEMFCs). The cost of the PEMFC stacks has been limiting its commercialization due to the inflated price of conventional platinum (Pt)-based catalysts. As a consequence, the authors of this paper focus on developing novel bi-metallic (Pt-Co) nano-alloy-catalyzed MEAs using the non-equilibrium impregnation–reduction (NEIR) approach with an aim to reduce the Pt content, and hence, the cost. Herein, the MEAs are fabricated on a Nafion® membrane with a 0.4 mgPtcm−2 Pt:Co electrocatalyst loading at three atomic ratios, viz., 90:10, 70:30, and 50:50. The High Resolution-Scanning Electron Microscopic (HR-SEM) characterization of the MEAs show a favorable surface morphology with a uniform distribution of Pt-Co alloy particles with an average size of about 15–25 µm. Under standard fuel cell test conditions, an MEA with a 50:50 atomic ratio of Pt:Co exhibited a peak power density of 0.879 Wcm−2 for H2/O2 and 0.727 Wcm−2 for H2/air systems. The X-ray diffractometry (XRD), SEM, EDX, Cyclic Voltammetry (CV), impedance, and polarization studies validate that Pt:Co can be a potential affordable alternative to high-cost Pt. Additionally, a high degree of stability in the fuel cell performance was also demonstrated with Pt50:Co50. Full article
