Sonochemical　synthesis　has　flourished　significantly　in　the　last　few　decades　for　the　preparation　of　pho-tocatalysts.　A　large　number　of　photocatalysts　have　been　prepared　through　sonochemical　techniques.　This　review　highlights　the　scope　of　sonochemistry　in　the　preparation　of　photocatalysts,　and　their　applications　in　energy　production　and　environmental　remediation.　Beside,　the　sonochemical　degradation　of　pollutants　is　discussed　in　detail.　The　progress　made　in　sonochemical　synthesis　and　the　future　perspective　for　this　technique　are　summarized　here.　This　review　may　create　more　enthusiasm　among　researchers　to　pay　extra　attention　to　the　sonochemical　synthesis　of　materials　and　add　their　useful　contribution　to　the　investiga-tion　of　new　materials　for　photocatalytic　and　other　applications.　This　will　propel　this　technique　toward　commercial　sonosynthesis　of　nanomaterials.　(c)　2022　Published　by　Elsevier　Ltd　on　behalf　of　The　editorial　office　of　Journal　of　Materials　Science　&　Technology.
