Dual-channel charges transfer strategy with synergistic effect of Z-scheme heterojunction and LSPR effect for enhanced quasi-full-spectrum photocatalytic bacterial inactivation: new insight into interfacial charge transfer and molecular oxygen activation

•Novel Z-scheme CdIn2S4/W18O49 heterojunction with dual-channel charges transfer path was fabricated.•The prepared catalysts exhibited excellent photocatalytic efficiency under both full-spectrum and NIR light irradiation.•CdIn2S4/W18O49 photocatalysts exhibited higher molecular oxygen activation activity compared with CdIn2S4 and W18O49.•h+, O2− and OH played the dominant role in the photocatalytic reaction system.•The enhanced photocatalytic activity was ascribed to the synergistic effect of Z-scheme heterojunction and LSPR effect.
