Plasmon-enhanced CO2 electroreduction based on metal oxide inverse opal supports decorated with bimetallic nanoparticles KU Leuven
This project uses an original approach for electrocatalytic CO2 reduction (eCO2RR). The catalysts are made using the physical method of cluster beam deposition onto a metal oxide inverse opal supports. Exploiting the exceptional size and composition control of cluster sources may enable the identification of novel high-performance eCO2RR by means of a combination of structural, spectroscopic, and reactivity experiments. The applicability of ...
Catalytic and solid state NMR spectroscopic study of bimetallic catalysts: synergisms between Lewis acid and transition metal sites in carbonylation and transfer hydrocyanation reactions KU Leuven
Catalytic coupling of two small molecules may proceed much faster if each molecule is activated on a discrete metal centre. Especially combinations of transition metals (TM) and Lewis acids (LA) can generate a special synergy in heterogeneous catalysis. In carbonylation of alcohols (or epoxides), CO and the alcohol (epoxide) are activated resp. by TM and LA sites; in transfer hydrocyanations, the slow steps are accelerated by binding of ...
Zirconium(IV)/Cerium(IV) bimetallic metal organic frameworks as novel redox active artificial proteases: a systematic study of molecular interactions and catalytic properties KU Leuven
Metal Organic Frameworks (MOFs) are a fascinating new class of porous material with applications ranging from gas storage for hydrogen power, absorptive materials for kidney dialysis, to novel catalysts for protein cleavage (hydrolysis). They are formed of metaloxygen clusters joined by carbon-based linkers to form highly structured crystals with well-defined pores. By varying the metal and linker species, an infinite range of MOFs can be ...
Tailored design of nanostructured bimetallic Pt-catalysts for (de)hydrogenation reactions Ghent University
Heterogeneous bimetallic Pt-based catalysts offer properties not found in monometallic Pt catalysts.
To develop improved Pt-based catalysts for (de)hydrogenation reactions, a strategy for controlled design of stable bimetallic nanocatalysts is proposed by means of atomic layer deposition (ALD). Optimization will be based on the variation of catalyst phase, shape and promoter element, and on managing deactivation by applying a protective ...

In situ XRF and XAS study of Atomic Layer Deposition on flat and porous sustrates - deposition of bimetallic materials. Ghent University
The research involves the development of synchrotron based measuring techniques for the in situ characterisation of an atomic deposition process of inorganic materials in/onto solids. As specific application the deposition and formation of bimetallic materilas are studied.
Epitaxial growth of (Ba,Ca)(Ti,Zr)O3 film on flexible metallic tape via chemical solution deposition Ghent University
Today, piezoelectric materials play an important role in numerous applications such as sensors, actuators, transducers, and energy harvesters. Piezoelectric energy harvesters cannot reach the efficiency and scale of solar cells or wind turbines, but they are excellent power sources where electrical cables are undesired and miniaturization is a key factor. However, Lead-based piezoelectric materials such as Pb(Zr,Ti)O3 is currently the most ...

Vibration-based prediction of fatigue damage accumulation in metallic structures by use of virtual sensing KU Leuven
Fatigue of metallic structures occurs when a structural component is subjected to cyclic loading.This problem arises for many engineering structures, such as railway bridges, wind turbines, and offshore structures. For existing structures, on site strain measurements allow to verify assumptions made in the design, including the response under dynamic loading, the number of load cycles the structure is subjected to, etc. This may allow for ...
