The applications of copper (Cu) and Cu-based nanoparticles, which are based on the earth-abundant and inexpensive copper metal, have generated a great deal of interest in recent years, especially in the field of catalysis. The possible modification of the chemical and physical properties of these nanoparticles using different synthetic strategies and conditions and/or via postsynthetic chemical treatments has been largely responsible for the rapid growth of interest in these nanomaterials and their applications in catalysis. In addition, the design and development of novel support and/or multimetallic systems (e.g., alloys, etc.) has also made significant contributions to the field. In this comprehensive review, we report different synthetic approaches to Cu and Cu-based nanoparticles (metallic copper, copper oxides, and hybrid copper nanostructures) and copper nanoparticles immobilized into or supported on various support materials (SiO2, magnetic support materials, etc.), along with their applications i...

Cu and Cu-Based Nanoparticles: Synthesis and Applications in Catalysis.

Cerium dioxide (CeO2, ceria) is becoming an ubiquitous constituent in catalytic systems for a variety of applications. 2016 sees the 40th anniversary since ceria was first employed by Ford Motor Company as an oxygen storage component in car converters, to become in the years since its inception an irreplaceable component in three-way catalysts (TWCs). Apart from this well-established use, ceria is looming as a catalyst component for a wide range of catalytic applications. For some of these, such as fuel cells, CeO2-based materials have almost reached the market stage, while for some other catalytic reactions, such as reforming processes, photocatalysis, water-gas shift reaction, thermochemical water splitting, and organic reactions, ceria is emerging as a unique material, holding great promise for future market breakthroughs. While much knowledge about the fundamental characteristics of CeO2-based materials has already been acquired, new characterization techniques and powerful theoretical methods are dee...

Fundamentals and Catalytic Applications of CeO2-Based Materials

The reduction of Fe 2 O 3 with hydrogen was studied. The thermodynamic analysis of the process implied that temperature-programmed reduction of the oxide should proceed in three steps, i.e. Fe 2 O 3  → Fe 3 O 4  → “FeO” → Fe, at X H 2 O / X H 2 ratio over 0.35, but in two steps, i.e. Fe 2 O 3  → Fe 3 O 4  → Fe, below that value. The idea was verified by TPR and XRD studies. Generally, the examinations confirmed the suggestions. The reduction is three-step reaction at high X H 2 O / X H 2 ratio, but two-step reaction at low that ratio. Additionally, it was revealed that at extremely low X H 2 O / X H 2 ratio the TP reduction is a one-step reaction, i.e. Fe 2 O 3  → Fe.

Barium-promoted Ru/carbon catalyst for ammonia synthesis: State of the system when operating

Ruthenium catalysts (4.6 wt.%) supported on the magnesium–aluminum spinel and promoted with barium (Ba:Ru=1:1 molar ratio) or caesium (Cs:Ru=1:1) were studied in the reaction of ammonia decomposition under a 1 bar pressure. Both Ba-Ru/MgAl 2 O 4 and Cs-Ru/MgAl 2 O 4 proved to be significantly more active than the unpromoted system (a factor of 10) and more active than the conventional magnetite-based catalyst used commonly in the NH 3 synthesis. However, the surfaces of the spinel-based catalysts were less active (TOF) than those of analogously promoted (Ba, Cs) ruthenium on carbon.
