For the first time, C-doped g-C3<\/sub>N4<\/sub>@C, N co-doped TiO2<\/sub> core-shell heterojunction photocatalyst was successfully prepared by an in-situ<\/i> one-pot hydrothermal bio-template approach, assisted by calcination treatment at 500\u202f\u00b0C. Kapok fibre was used as a bio-templates and in-situ<\/i> C doping in g-C3<\/sub>N4<\/sub> and TiO2<\/sub> during the formation of core-shell heterojunction photocatalyst. Moreover, the used of urea as g-C3<\/sub>N4<\/sub>-precursor also contribute to band-gap narrowing by an in-situ<\/i> carbon and nitrogen doping in TiO2<\/sub>. Various characterisation techniques were employed to understand the effect TiO2<\/sub> precursor concentration on the evolution of core-shell nanostructure heterojunction photocatalyst that can affect and boost the catalytic activity. The detailed understanding of the concurrent growth of C-doped g-C3<\/sub>N4<\/sub> (CCN) and C, N co-doped TiO2<\/sub> mechanism, as well as the formation of core-shell nanostructures heterojunction\u00a0\u2026<\/p>\n
