TL;DR: A solar thermal-promoted photocatalyst is constructed, an ultrathin "biphasic" ordered-disordered D-HNb3 O8 junction, which performs two disparate spectral selective functions of photoexcitation by ordered structure and thermal activated conversion via disordered lattice for combinatorial photothermal mediated catalysis.
