Biomass screening for syngas production by flash photopyrolysis

Hubert Girault, Mathieu Soutrenon, Wanderson Oliveira Da Silva

A few seconds flash photopyrolysis is used as efficient screening tool for the investigation of selected biomass in producing syngas, hydrogen and biochar. This innovative approach allowed rapid pyrolysis of the biomass, which was followed by a precise gas ...

Hydrogen production by waste tire recycling by photo-pyrolysis

Hubert Girault, Jordi Espin Marti, Luc Sébastien Bondaz, Bhawna Nagar, Wanderson Oliveira Da Silva

Waste tires are a major environmental concern due to their non-degradable nature and the large area occupied by them in landfills worldwide. Several recycling processes have been applied to minimize the high amount of waste tire disposal; in particular, py ...

Banana split: biomass splitting with flash light irradiation

Hubert Girault, Bhawna Nagar, Wanderson Oliveira Da Silva

Biomass splitting into gases and solids using flash light irradiation is introduced as an efficient photo-thermal process to photo-pyrolyze dried natural biomass powders to valuable syngas and conductive porous carbon (biochar). The photo-thermal reactions ...

Visible-Light-Driven Water Oxidation on Self-Assembled Metal-Free Organic@Carbon Junctions at Neutral pH

Hubert Girault, Astrid Johana Olaya Avendano, Julieta Soledad Riva, Wanderson Oliveira Da Silva, Dominika Baster

Sustainable water oxidation requires low-cost, stable, and efficient redox couples, photosensitizers, and catalysts. Here, we introduce the in situ self-assembly of metal-atom-free organic-based semiconductive structures on the surface of carbon supports. ...

Flash light synthesis of noble metal nanoparticles for electrochemical applications: silver, gold, and their alloys

Hubert Girault, Victor Costa Bassetto, Carlos Manuel De Melo Pereira, Wanderson Oliveira Da Silva

The synthesis of noble metal nanoparticles (i.e., silver and gold) for electrochemical applications has been widely studied using mainly wet synthesis chemical methods or electrochemical deposition methods. In this work, we propose a single-step flash phot ...
