Herein,　we　reported　hydrothermal　synthesis　of　Sm2MoO6-TiO2-bentonite　nanocomposite　(SMTB)　and　its　application　as　a　higher　efficient　electrocatalyst　and　photocatalyst.　The　as-prepared　SMTB　active　catalysts　for　greater　electrocatalytic　activity　with　a　low　overpotential　value　of　347　mV　to　achieve　a　current　density　of　10　mA　cm-2　in　1.0　M　KOH　for　the　oxygen　evolution　reaction　(OER).　The　corresponding　slope　of　the　Tafel　plot　is　as　low　as　53　mV　dec-1　compared　to　other　catalysts　such　as　Sm2MoO6　(SM),　TiO2　and　Sm2MoO6-TiO2　(SMT).　Also　investigated　the　very　stable　performance　of　the　SMTB　electrode　using　cyclic　voltammetry　(CV),　and　the　results　reveal　negligible　loss　in　electrochemical　activity　for　1000　CV　cycles.　Furthermore,　the　SMTB　photocatalytic　performance　has　been　demonstrated　by　degradation　of　the　pharmaceutical　pollutant　ciprofloxacin　(CF).　The　photocatalytic　performance　has　been　further　investigated　for　optimum　catalyst　dosage,　pH　of　the　reaction　medium　and　stability　of　the　catalysts.
