Special Issue Information

Dear Colleagues,

The ever-increasing demand for energy and the negative environmental impacts imposed by using fossil fuels have called for efficient energy conversion and storage technologies. Polymer electrolyte membrane fuel cells (PEMFCs) and lithium air (oxygen) batteries are among the most promising technologies to answer this call. Oxygen reduction reaction (ORR) is a cathode reaction in PEMFCs and lithium-oxygen batteries. The sluggish ORR requires the development of highly-efficient ORR catalysts before these technologies are viable and can be widely deployed in the market. Consequently, tremendous research efforts have been made in ORR catalysts and many highly-active and stable catalysts have emerged. This Special Issue aims to cover recent progress and trends in synthesizing, characterizing and evaluating advanced electrocatalysts for ORR, as well as a theoretical understanding of ORR that provides rational design guides for high performance ORR catalysts.

Three-dimensionally ordered macroporous (3DOM) NiCe catalysts with different Ni/Ce molar ratio were fabricated using the colloidal crystal templating method. The physic-chemical properties of the samples were characterized by various techniques, including N2 adsorption–desorption, X-ray diffraction (XRD), transmission electron microscopy (TEM), Raman, and H2-temperature-programmed reduction (TPR) characterizations. The results revealed that the 3DOM NiCe samples preserved the three-dimensionally ordered macroporous channels with interlinked micro- or mesoporous structure and highly dispersed nickel oxide species in the framework upon different amount of nickel incorporation. In the evaluation of the oxidative dehydrogenation (ODH) of propane, the 3DOM NiCe catalysts exhibited higher selectivity and yield to propene than the amorphous NiCe catalyst. An optimum yield of propene of 11.9% with the 30.3% propane conversion at 375 °C was obtained over the 3DOM 2NiCe catalyst. Combining XRD, TPR, and Raman analysis, it could be found that the nickel incorporation in CeO2 lattice produced a high concentration of oxygen vacancies that were the active sites for the oxidative dehydrogenation of propane. Besides this, the 3DOM structure promoted the rapid diffusion of the reactants and products—favorable for the generation of propene in the ODH of propane. Full article
