Special Issue Information

Dear Colleagues,

Great advances have been recorded in heterogeneous catalysis and/or electrocatalysis as a result of the ongoing progress in nanotechnology that provides efficient approaches and advanced methods for the design of nano-structured composite materials subjected to specific nanomorphologies and enhanced metal–metal and metal–support interactions. Surface-induced and/or support-mediated promotion of catalytic performance through metal–metal and metal–support interactions, as well as surface morphology (size/shape of catalyst nanoparticles), are issues that have a crucial role in determining and improving the efficiency and robustness of heterogeneous catalytic materials for specific applications. Fine-tuning of critical physicochemical properties of the materials, such as electron affinity (work function), oxidation state, and morphology of nanoparticles is therefore achieved, enabling catalytic activity, selectivity and time-on-stream stability optimization of the materials for reactions with high environmental and energy importance.

Apparently, heterogeneous catalysis and electrocatalysis played, play, and will continue to play a major role in industrial processes for large-scale synthesis of commodity chemicals of global importance and in catalytic systems that possess a critical role in energy generation and environmental protection approaches. Among others, such ecofriendly and cost-efficient applications involve, for example, deNOx, deN2O, and VOCs emissions control systems, waste treatment, photocatalytic, biorefinery, CO2 utilization and fuel cells applications, as well as hydrocarbons processing for H2, added-value chemicals and liquid fuels production.

The titled Special Issue aims to cover current experimental studies, in the field of nanomaterials synthesis, their characterization, and application in heterogeneous catalysis and/or electrocatalysis. Therefore, advanced synthesis routes, characterizations, catalytic and electrocatalytic activity/stability evaluation, and fundamental understanding of structure–activity relationships or possible metal–metal and metal–support interactions under desired reactions are very welcome.

Oxidative Thermal Sintering and Redispersion of Rh Nanoparticles on Supports with High Oxygen Ion Lability
Catalysts 2019, 9(6), 541; https://doi.org/10.3390/catal9060541 - 17 Jun 2019

The thermal sintering under oxidative conditions of Rh nanoparticles supported on oxides characterized by very different oxygen storage capacities (OSC) and labilities was studied at 750 and 850 °C. Under sintering conditions, significant particle growth occurred for Rh/γ-Al2O3 (up to 120% at 850 °C). In striking contrast, Rh/ACZ (alumina–ceria–zirconia) and Rh/CZ (ceria–zirconia) exhibited marked resistance to sintering, and even moderate (ca. −10% at 850 °C) to pronounced (ca. −60% at 850 °C) redispersion of the Rh. A model is proposed based on a double-layer description of metal–support interactions assigned to back-spillover of labile oxygen ions onto the Rh particles, accompanied by trapping of atomic Rh by the resulting surface oxygen vacancies. This model accounts for the observed resistance to sintering and actual redispersion of Rh, consistent with both alternative sintering mechanisms, namely Ostwald ripening (OR) or particle migration and coalescence (PMC).

1. Title: Exsolved nanoparticle systems for CH4 conversion to syngas
Author: Kalliopi Kousi <[email protected]>
Abstract: Currently the main process for H2 and syngas production is the reformation of CH4, which however suffers from deactivation of the catalysts used via agglomeration and carbon deposition. Exsolution has been shown to be an approach to produce confined nanoparticles, which in turn are more stable against coalescence and coke deposition, and, at the same time strained, generally displaying enhanced activity. In this study, we design, prepare and tailor perovskite systems with exsolved nanoparticles and apply them for the reforming of CH4 to syngas. Detailed comparison with reference samples prepared by a conventional way of depositing particles on the surface of supports is presented, in terms of their resistance to coking, conversion and selectivity over syngas production
