Metal‐Based Nanocatalysts: Metal‐Based Nanocatalysts via a Universal Design on Cellular Structure (Adv. Sci. 3/2020)

Smart Nanocatalysts with Streamline Shapes

Particulate catalysts with streamline shapes have important impacts on fluid-related reactions, and they need to be properly characterized. However, utilization of streamline-shaped catalysts for heterogeneous catalysis has remained an unexplored area due to the lack of easy-to-use techniques to produce such shaped catalysts, especially at the small length scale of the submicron to micron regim...

Hydrogen Production VIA Polyoxymethylene Degradation using Copper Nanocatalysts

Polyoxymethylene (POM) is an engineering thermoplastic. Formaldehyde is the monomer unit of this polymer. Depolymeraization of POM occurs at 100 o C and yields formaldehyde whereas thermal degradation occurs at 270 o C. During thermal degradation, POM splits into carbon dioxide, water and formic acid. It has been proved that formaldehyde can be used as hydrogen source, when metallic nanoparticl...

Rapid Synthesis of Rhodium–Palladium Alloy Nanocatalysts

Noble metals are widely used as catalysts in a variety of key industrial processes. In particular, rhodium is used to catalyze the reduction of NOx to N2 and O2 in exhaust gas abatement and is also used in the conversion of bulk hydrocarbon feedstocks and syngas into more highly oxygenated hydrocarbons (e.g. , hydroformylation). 2] Palladium also plays a myriad of critical roles, including CO-t...

Mechanistic Understanding of Toxicity from Nanocatalysts

Nanoparticle-based catalysts, or nanocatalysts, have been applied in various industrial sectors, including refineries, petrochemical plants, the pharmaceutical industry, the chemical industry, food processing, and environmental remediation. As a result, there is an increasing risk of human exposure to nanocatalysts. This review evaluates the toxicity of popular nanocatalysts applied in industri...
