Interfacial　charge　transfer　is　crucial　in　the　efficient　conversion　of　solar　energy　into　fuels　and　electricity.　In　this　paper,　heterojunction　composites　were　fabricated,　comprised　of　anatase　TiO2　with　different　percentages　of　exposed　{101}　and　{001}　facets　and　nitrogen-doped　quantum　dots　(NGQDs)　to　enhance　the　transfer　efficiency　of　photo-excited　charge　carriers.　The　photocatalytic　performances　of　all　samples　were　evaluated　for　RhB　degradation　under　visible　light　irradiation,　and　the　hybrid　containing　TiO2　with　56%　{001}　facets　demonstrated　the　best　photocatalytic　activity.　The　excellent　photoactivity　of　TiO2/NGQDs　was　owed　to　the　synergistic　effects　of　the　following　factors:　(i)　The　unique　chemical　features　of　NGQDs　endowed　NGQDs　with　high　electronic　conductivities　and　provided　its　direct　contact　with　the　TiO2　surface　via　forming　Ti-O-C　chemical　bonds.　(ii)　The　co-exposed　{101}　and　{001}　facets　were　beneficial　for　the　separation　and　transfer　of　charge　carriers　in　anatase　TiO2.　(iii)　The　donor-acceptor　interaction　between　NGQDs　and　electron-rich　{101}　facets　of　TiO2　could　remarkably　enhance　the　photocurrent,　thus　hindering　the　charge　carriers　recombination　rate.　Extensive　characterization　of　their　physiochemical　properties　further　showed　the　synergistic　effect　of　facet-manipulated　electron-hole　separation　in　TiO2　and　donor-acceptor　interaction　in　graphene　quantum　dots　(GQDs)/TiO2　on　photocatalytic　activity.
