2D arrangement of palladium meso-dots for H2 sensing

Pd dots electrochemically grown through a meso-structured membrane. Thanks to controlled span between the dot network, quantitative H2 sensing is achieved Research themes Collaborations & Contracts Research topics In the priority themes of research programs dedicated to energy, an important part concerns the design and improvement of technological bricks for energy storage and conversion. In this context, and in the continuity of my activities, my research concerns the electrochemical storage of energy (supercapacitors and circulating batteries) and the hydrogen vector (detection and electrolysis). Our research activities concern the development of methods of assembly of objects for the construction of ordered buildings and the formulation of complex materials for their integration into devices for applications taking advantage of their specific physico-chemical properties. In these areas, the characteristics and performance of devices are fundamentally linked to the interfaces involved, especially since the widespread use of nanostructured materials or the introduction of electroactive molecules for their design. The interfaces can be solid-solid and solid-gas for gas sensors, solid-solid and solid-liquid for supercapacitors and circulating batteries, or triple, solid-liquid-gas, for electrolysis. If in the case of resistive sensors, they are the transducers of detection, in the case of electrochemical storage and electrolysis systems, they must allow an optimum transfer of electronic and ionic charges passing through the electrode materials or on their surface for maximizing energy efficiency and power. The aim of our work is to set up a chemical engineering based on a fine control of the interfaces involved for the reasoned formulation of materials and the integration of said formulations into functional devices. It is the totality of the approach that interests us, the one that goes from the synthesis of the material and molecules to the evaluation of the performance of the devices, the one that imposes the use of characterization techniques at different scales and the modeling of the observed phenomena, the one that allows the elucidation of the mechanisms of synthesis as those of (dis)functioning … Collaborations & Contracts
