Structural and surface characterizations showed that the presence of g-C<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub> notably affected the light absorption characteristics of TiO<jats:sub>2<\/jats:sub>. The g-C<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub>\/TiO<jats:sub>2<\/jats:sub> heterojunctions with metal-free exposed surfaces were directly used as biocompatible photocatalysts for simulated jaundice phototherapy under low-power green-light irradiation. The photocatalytic activity and stability of g-C<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub>\/TiO<jats:sub>2<\/jats:sub> were enhanced relative to pure P25 or g-C<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub>, which could be ascribed to the effective Z-scheme separation of photo-induced charge carriers in g-C<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub>\/TiO<jats:sub>2<\/jats:sub> heterojunction. The photoactivity was maximized in the 4 wt.% g-C<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub>-coated P25, as the bilirubin removal rate under green light irradiation was more than 5-fold higher than that under the clinically-used blue light without any photocatalyst. This study approves the future applications of the photocatalyst-assisted bilirubin removal in jaundice treatment under moderate green light which is more tolerable by humans.<\/jats:p>","DOI":"10.1038\/srep44338","type":"journal-article","created":{"date-parts":[[2017,3,13]],"date-time":"2017-03-13T11:00:03Z","timestamp":1489402803000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Efficient Photocatalytic Bilirubin Removal over the Biocompatible Core\/Shell P25\/g-C3N4 Heterojunctions with Metal-free Exposed Surfaces under Moderate Green Light Irradiation"],"prefix":"10.1038","volume":"7","author":[{"given":"Shifei","family":"Kang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hengfei","family":"Qin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongkui","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xia","family":"Bai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xi","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Di","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yangang","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lifeng","family":"Cui","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2017,3,13]]},"reference":[{"key":"BFsrep44338_CR1","doi-asserted-by":"publisher","first-page":"4156","DOI":"10.1073\/pnas.0630614100","volume":"100","author":"WD Huang","year":"2003","unstructured":"Huang, W.
