Photo-Electrochemical Conversion of CO2 Under Concentrated Sunlight Enables Combination of High Reaction Rate and Efficiency

Autor: Etienne Boutin, Mahendra Patel, Egon Kecsenovity, Silvan Suter, Csaba Janáky, Sophia Haussener

Photo-electrochemical production of solar fuels from carbon dioxide, water, and sunlight is an appealing approach. Nevertheless, it remains challenging to scale despite encouraging demonstrations at low power input. Higher current densities require n

Continuous-flow electrolyzers allow CO2 reduction at industrially relevant rates, but long-term operation is still challenging. One reason for this is the formation of precipitates in the porous cathode from the alkaline electrolyte and the CO2 feed.

Solution Combustion Synthesis of Complex Oxide Semiconductors

Autor: Krishnan Rajeshwar, M. Molnár, Mohammad Kabir Hossain, Egon Kecsenovity, Csaba Janáky, András Varga

Publikováno v: International Journal of Self-Propagating High-Temperature Synthesis. 27:129-140

This is a perspective of the role that combustion synthesis, specifically solution combustion synthesis, has played in the development of ternary and quaternary metal oxide semiconductors, and materials derived from these compounds such as composites

Height and diameter dependence of carbon nanotube forests on the porosity and thickness of catalytic layers

Autor: Zsuzsanna Pápa, Dora Fejes, Klara Hernadi, Zsolt Toth, Egon Kecsenovity, Judit Budai

Publikováno v: Applied Surface Science. 428:885-894

Syntheses of highly ordered carbon nanotube (CNT) forests were studied from the aspect of the quality of CNTs and the properties of Fe-Co catalyst. CNT forests were grown by catalytic chemical vapor deposition. The amount of catalyst was varied in tw

Electrical transport in onion-like carbon - PMMA nanocomposites

Autor: Claudio Grimaldi, Vladimir L. Kuznetsov, László Forró, Maryam Majidian, Arnaud Magrez, Egon Kecsenovity

We report electrical conductivity measurements of Polymethyl-methacrylate filled by onion-like carbon particles with primary particle size of $\approx 5$ nm. We shown that the conductivity $\sigma$ is exceptionally high even at very low loadings, and
