Sustainable Method Produces High-Purity Material For Use In Green Hydrogen Production
Publicado em 12 de maio de 2025
A group of researchers affiliated with the Center for Innovation in New Energies (CINE) has developed a method for purifying materials that is simple, economical and has a low environmental impact. The scientists have managed to improve the efficiency of a film that can be used in some green hydrogen production processes.
Known as mullite-type bismuth ferrite (Bi ₂ Fe ₄ O ₉), the material has been used as a photoelectrocatalyst in the production of hydrogen by photoelectron oxidation, [...]

Scientists develop catalyst designed to make ammonia production more sustainable
Publicado emCreated at a FAPESP-supported research center, the material helps produce ammonia by electrochemical reduction of nitrogen gas, dispensing with the high temperature and pressure required by the conventional method. Ammonia is one of the most widely produced chemicals in the world, and is used in a great many manufacturing and service industries. The conventional production technology is the Haber-Bosch process, which combines nitrogen gas (N ) and hydrogen gas (H ) in a reactor in the [...]ver notícia -
Brazilian scientists reveal method of converting methane gas into liquid methanol
Publicado em 03 agosto 2022A group of researchers has succeeded in converting methane into methanol using light and dispersed transition metals such as copper in a process known as photo-oxidation. According to an article reporting the study published in Chemical Communications, the reaction was the best obtained to date for conversion of methane gas into liquid fuel under ambient conditions of temperature and pressure (25 °C and 1 bar respectively). The term bar as a unit of pressure derives from the Greek word [...]ver notícia
