From Single Atoms to Nanoparticles: Pathways Toward Efficient and Durable Pt/TiO2 Photocatalysts

open access: yesAdvanced Functional Materials, EarlyView.
Platinum single atoms on TiO2 nanosheets evolve into clusters and nanoparticles under ethanol photoreforming and thermal treatments. By controlling deposition and post‐treatments, particle size and location on specific facets are modulated. The study reveals how stability pathways determine efficiency, guiding the design of more durable photocatalysts.

Life cycle environmental performance of methanol production through photocatalytic dry methane reforming

open access: yesJournal of CO2 Utilization
Photocatalytic dry methane reforming uses light energy and a nanostructured photocatalyst to convert both carbon dioxide and methane gas to syngas for production of fuels and value-added chemicals. The conversion of these two greenhouse gases (GHG) makes

Modeling and simulation of an isothermal reactor for methanol steam reforming

open access: yesActa Scientiarum: Technology, 2014
Due to growing electricity demand, cheap renewable energy sources are needed. Fuel cells are an interesting alternative for generating electricity since they use hydrogen as their main fuel and release only water and heat to the environment.

Intensification of methanol steam reforming process using Cu-modified Ni-based supported catalysts [PDF]

open access: yes, 2019
Hydrogen is conventionally manufactured in large scale by the steam reforming of methane or naphthas. The perspective of using hydrogen as a fuel depends of finding alternatives to the existing production technologies and feedstock. Oxygenated compounds
