The ZnO seeds were deposited on the FTO substrate heated at 350 W C by spray pyrolysis of a zinc acetate solution in a water ethanol mixture. The structure of seeds was tuned by the ethanol water ratio, Γ, which controls the solvent evaporation rate of drops impinging the substrate. The relationship between the microstructure and optical properties of the ZnO NR films and the photocatalytic antibacterial activity for Escherichia coli abatement, was determined through a detailed characterization of the material. The higher photocatalytic antibacterial activity was performed by ZnO NR films grown on seeds deposited from solutions with Γ in the 0.0–0.03 range. With these films, the population of viable E. coli dropped more than six orders, from 8 × 108 to 4 × 102 CFU. These results show the potential of these materials in water disinfection.Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica - ConcytecengIWA PublishingWater Science and Technology-Water Supplyinfo:eu-repo/semantics/openAccessnanorodsphotocatalytic disinfectionspray pyrolysisInfluence of pyrolytic seeds on ZnO nanorod growth onto rigid substrates for photocatalytic abatement of Escherichia coli in waterinfo:eu-repo/semantics/articlereponame:CONCYTEC-Institucionalinstname:Consejo Nacional de Ciencia Tecnología e Innovacióninstacron:CONCYTEC20.500.12390/1251oai:repositorio.concytec.gob.pe:20.500.12390/12512025-09-23 13:28:52.57http://purl.org/coar/access_right/c_14cbinfo:eu-repo/semantics/closedAccessmetadata only accesshttps://repositorio.concytec.gob.peRepositorio Institucional CONCYTECrepositorio@concytec.gob.pe#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="6756c17c-bf2c-4994-9e25-669971fc2bb6"> <Type xmlns="https://www.openaire.eu/cerif-profile/vocab/COAR_Publication_Types">http://purl.org/coar/resource_type/c_1843</Type> <Language>eng</Language> <Title>Influence of pyrolytic seeds on ZnO nanorod growth onto rigid substrates for photocatalytic abatement of Escherichia coli in water</Title> <PublishedIn> <Publication> <Title>Water Science and Technology-Water Supply</Title> </Publication> </PublishedIn> <PublicationDate>2014</PublicationDate> <DOI>https://doi.org/10.2166/ws.2014.068</DOI> <ISI-Number>348791100017</ISI-Number> <Authors> <Author> <DisplayName>Sanchez, L</DisplayName> <Person id="rp02477" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Guz, L</DisplayName> <Person id="rp03612" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Garcia, P</DisplayName> <Person id="rp01512" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Ponce, S</DisplayName> <Person id="rp01644" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Goyanes, S</DisplayName> <Person id="rp01692" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Marchi, MC</DisplayName> <Person id="rp02476" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Candal, R</DisplayName> <Person id="rp01475" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Estrada, W</DisplayName> <Person id="rp01889" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Rodriguez, J</DisplayName> <Person id="rp01477" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>IWA Publishing</DisplayName> <OrgUnit /> </Publisher> </Publishers> <Keyword>nanorods</Keyword> <Keyword>photocatalytic disinfection</Keyword> <Keyword>spray pyrolysis</Keyword> <Abstract>ZnO nanorods (ZnO NRs) were grown on ZnO seeded fluorine doped tin oxide (FTO) substrates at low temperatures (90 W C) from Zn2þ precursors in alkaline aqueous solution.
