The　authors　describe　a　highly　efficient　photoelectrochemical　(PEC)　scheme　for　the　determination　of　hydrogen　peroxide　(H2O2).　BiVO4　microrods　were　hydrothermally　synthesized　and　deposited　on　fluorine　-　doped　tin　oxide　(FTO)　glass　which　acts　as　the　working　electrode.　Scanning　electron　microscopy,　X-ray　powder　diffraction　and　Raman　spectroscopy　were　utilized　for　the　characterization　of　the　microrods.　On　irradiation　with　visible　light,　the　holes　generated　in　the　microrods　are　capturing　electrons　from　H2O2　to　produce　a　photocurrent　at　an　operating　potential　of　0　V　vs.　Ag/AgCl.　Under　optimal　conditions,　the　photocurrent　increases　with　the　concentration　of　H2O2　in　the　range　from　50　mu　mol　center　dot　L-1　to　1.5　mmol　center　dot　L-1,　and　the　limit　of　detection　is　8.5　mu　mol　center　dot　L-1　(at　3　sigma).　A　repeatability　and　intermediate　precision　of　＜=　6.6%　was　accomplished　at　H2O2　levels　of　0.1,　0.5　and　1.0　mmol　center　dot　L-1.　The　method　was　applied　to　the　determination　of　H2O2　in　spiked　sterilized　milk　samples　and　gave　satisfactory　results.　As　the　method　works　at　zero　potential,　the　photocurrent　can　be　measured　with　simple　instrumentation　such　as　digital　multimeters,　and　this　will　enable　expensive　electrochemical　workstations　to　be　replaced　in　future.
