Many studies are focused on the development of materials for converting carbon dioxide into multicarbon oxygenates such as methanol and ethanol, because of their higher energy density and wider applicability. In this work, ...

Copper(I) oxide (Cu2O) was electrochemically deposited on fluorine-doped tin oxide (FTO) glass electrode and covered with a thin layer of poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS). The electrode ...

TiO2 nanotube (NT) arrays were modified with thin films of polydopamine (PDA) and Ag nanoparticles (NP) and were used as electron storage centers on a photoelectrode surface, in order to drive the reduction of CO2 to ...

The unbalanced concentration of CO2 in the atmosphere has received great attention due to severe effects on the planet. However, as human progress is still growing exponentially, CO2 emissions continue to be a major concern ...

This work describes the use of a thin film of Ru3(BTC)2 metal-organic framework (MOF) deposited onto Ti/TiO2 nanotubes as a photocathode in CO2 reduction. This approach combines the advantages of the ruthenium MOF as a ...

A fotoeletrorredução catalítica tem mostrado ser uma alternativa para a conversão do CO2 em compostos orgânicos com valor comercial agregado, reduzindo a sua emissão na atmosfera. A eficiência desse processo e a seletividade ...

The performance of the heterogeneous photocatalysis in wastewater treatment for the removal of organic pollutants, as well as for gaseous emissions, is associated to semiconductor photo-activity. TiO2 is a semiconductor ...
