Synthesis, characterization and evaluation of the photocatalytic properties of WO3 obtained through the polyol methodSíntese, caracterização e avaliação das propriedades fotocatalíticas do WO3 obtido através do método poliol
(2021-01-01)
This work shows a synthetic route mediated by tetraethylene glycol (P. E. 325 ° C) in which tungstic acid is used as the starting material. The formation of a stable blue suspension was observed during the course of the ...
Desenvolvimento de argamassa translúcida fotocatalítica para pavimentação urbana
(2019)
A utilização de partículas de vidro reciclado na argamassa fotocatalítica traz a possibilidade de transmissão de luz ao longo de toda a camada, fazendo com que a radiação solar penetre em seu interior, ativando os ...
Synthesis, characterization, and application of micro- and nanomaterials for the removal of organic contaminants from groundwater and wastewater
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2020-12-03)
The increasing presence of chemicals and pharmaceuticals in the aquatic environment represents a latent threat both to ecosystems and to human health. Conventional treatment methods for water hardly eliminate these pollutants, ...
PbO2 decorated ZnO-TiO2 core-shell nanoflower structures by zinc anodising for photo- and anodic degradation of Reactive Black-5 dye
(Iop Publishing Ltd, 2020-09-01)
This work shows that metallic zinc can be used as a low-cost substrate or electrode for photocatalyst and electrocatalyst use by anodising in mild bicarbonate solution. Electrochemical anodising was used to produce ZnO ...
