Com metodologia de síntese adotada e aplicada foi possível sintetizar os pós de
BaMoO4 em tempos de 1, 2, 4 e 8 minutos com morfologias em forma de octaedros, com
arranjo atômico estrutural tetragonal do tipo scheelita sem constar a presença de fases adicionais nas amostras puras ou com os surfactantes.
Os resultados de MEV-FEG apresentaram que as partículas seguiram um padrão de crescimento pelo mecanismo de ostwald ripening, em que levou a formação de cristais ou micro-octaedros com planos bem definidos e com poucos ou sem defeitos. Foi possível ainda observar que os surfactantes influenciaram no crescimento e forma dos cristais, sobre tudo o surfactante Setil, que para síntese de 1 minuto apresentou uma formação não octaédrica para seus cristais como as demais amostras em mesmo tempo, além da formação de octaedros bem definidos em 4 minutos que também não é o que ocorre com as outras amostras em 4 minutos. As analises de FL apresentaram espectros de emissão característicos para molibdatos de bário como observado na literatura. No entanto, o Sbenzol exerceu influência nas amostras sintetizadas, deslocando as emissões para comprimentos de ondas menores, na faixa do azul.
A rodamina B foi o corante dentre os três escolhidos que apresentou maior interação com o material sintetizado, sendo usado para verificar as propriedades de fotodegradação do material.
Das amostras escolhidas para verificar as propriedades de fotocatálise, apenas as de maiores tempos de síntese (8 minutos) e com surfactantes apresentaram melhores resultados na descoloração do corante rodamina B, com descoloração a cima de 70%.
