Introduction

Delivering a Modifying Element to Metal Nanoparticles via Support: Pt–Ga Alloying during the Reduction of Pt/Mg(Al,Ga)Ox Catalysts and Its Effects on Propane Dehydrogenation

“…Development of sustainable and efficient catalytic processes requires diverse methods for manipulating catalyst composition and structure, which determine catalysts’ performance. − The active components of many industrial heterogeneous catalysts are composed of supported metal nanoparticles, − and alloying with additional elements is an important method for manipulating their composition and structure. − The catalytic behavior of alloyed bimetallic nanoparticles is often markedly different from that of their monometallic counterparts or bulk alloys with equivalent composition due to a combination of geometric and electronic effects. − The extent of alloying and its effects on catalytic activity crucially depend on the catalyst preparation procedure, − the nature of the support, − and the reaction environment. , Therefore, the influence of these factors must be better understood to fully exploit alloying for rational catalyst design and optimization.…”

“…Bimetallic catalysts containing Pt are particularly important from a technological perspective because Pt catalysts are heavily employed in large-scale hydrocarbon processing and other industrially relevant reactions. ,,, A specific category of Pt-based catalysts, which includes, but is not limited to, Pt–In, , Pt–Ge, Pt–Ga, ,, and most importantly Pt–Sn, − ,, has been the subject of intense optimization studies. Such catalysts are increasingly relevant for on-purpose alkane dehydrogenation processes , and also provide convenient models for elucidating general principles behind alloying effects in catalysis.…”

Chemoselective single-site Earth-abundant metal catalysts at metal–organic framework nodes

“…Metal oxides, metal alloys and metal nanoparticles dispersed on oxide supports form the cornerstone of heterogeneous catalysts used in chemical and petrochemical industries 1 2 . However, the presence of multiple active sites makes selectivity difficult to achieve in traditional heterogeneous catalysis.…”

High-throughput activity screening and sorting of single catalyst particles with a droplet microreactor using dielectrophoresis

“…olid catalysts are important materials in the chemical industry and are used to facilitate chemical reactions in an energy-effective and selective way; this is why catalysis is involved in the production of >80% of all chemical products 1,2 . Solid catalysts come in many different shapes and sizes, but what they have in common is that they are often micrometre-sized, structured particles with a well-defined porosity.…”

“…Characterization of the multi-component fluid catalytic cracking (FCC) catalyst 1,27,28 would be of great benefit in high-throughput sorting due to its interparticle heterogeneities. FCC is the main chemical process in oil refining for the production of gasoline and propylene, using the residue of crude oil distillation as a feedstock.…”
