Effect of peptide aerogel composite on silver nanoparticles as a catalyst for electrochemical CO₂ reduction

Electrochemical reduction of carbon dioxide (CO₂RR) product distribution has been found to be dependent on several key factors, such as catalyst surface morphology, stability, and porosity. Metal-modified carbon-based materials have received a lot of attention in CO₂RR. However, designing a highly active metal carbon...

3D Printed Scaffolds for Monolithic Aerogel Photocatalysts with Complex Geometries

Monolithic aerogels composed of crystalline nanoparticles enable photocatalysis in three dimensions, but they suffer from low mechanical stability and it is difficult to produce them with complex geometries. Here, an approach to control the geometry of the photocatalysts to optimize their photocatalytic performance by introducing carefully...

Novel circular economy business model of high-added value products for energy efficiency: from C&DW to aerogels

Since the Industrial Revolution, humanity’s use of natural resources has been basically the same: TAKE, MAKE and THROW AWAY; which consequently led to the indispensable problems of waste materials. Around 461 million tons of Construction & Demolition Waste (C&DW), excluding excavation materials, are yearly generated in EU28. This undoubtedly...

Release of hydrogen from nanoconfined hydrides by application of microwaves

The release of hydrogen from solid hydrides by thermolysis can be improved by nanoconfinement of the hydride in a suitable micro/mesoporous support, but the slow heat transfer by conduction through the support can be a limitation. In this work, a C/SiO₂ mesoporous material has been synthesized and employed as matrix for...
