Facile sonochemical method for preparation of Cs2HgI4 nanostructures as a promising visible-light photocatalyst

Attempts are continuing to discover novel and efficient solutions to promote water grade and industrial sewage treatment. For the first time, we present a novel Cs2HgI4 photocatalyst functional below visible radiation. Cs2HgI4 nano photocatalyst has been prepared via an accelerated sonochemical appr...
