Interfacial charge separation in In2S3/N-BC@PVA evaporator for synergistic water disinfection and purification

• A novel In 2 S 3 /N-BC@PVA hydrogel evaporator was developed for water purification. • The In 2 S 3 /N-BC heterojunction facilitated interfacial charge redistribution and separation. • Synergistic effect achieves >99% ARB and >95% ARG removal. • The evaporator achieves a high evaporation rate (3.93 kg m -2 h -1 ).
