Single　metal　atom　oxide　catalysts　(SMAOs)　have　impressive　catalytic　efficiency　because　they　maximize　the　use　of　atoms,　and　their　unique　electronic　structures　in　the　reactions.　We　developed　a　single　tungsten/cobalt　atom　oxide　anchored　on　the　TiO2-rGO　catalyst　(TPWCoR)　from　TiO2　P25-rGO　and　heteropoly　acid　with　tungsten　and　cobalt.　Electron　microscope　characterization　showed　that　a　significant　amount　of　single　tungsten/cobalt　atom　oxide　(ST/CAO)　was　uniformly　deposited　on　TiO2　P25　nanoparticle.　The　transition　metal　atoms　are　equally　spread　throughout　on　TiO2　P25-rGO　material,　according　to　aberration　corrected　high-angle　annular　dark-field　scanning　transmission　electron　microscopy　(HAADF-STEM).　The　hydrogen　evolution　reactions　and　oxygen　evolution　reactions　(HER/OER)　are　crucial　for　electrochemical　water　splitting,　and　the　TPWCoR　nanocatalyst　is　extremely　active　and　stable　for　these　processes.　The　TPWCoR　possessing　a　higher　number　of　active　sites,　offers　current　densities　of　10　mA　cm-2　at　144　mV　for　HER　and　10　mA　cm-2　at　366　mV　for　OER　in　alkaline　medium　with　a　Tafel　slope　of　114.2　mV　dec-　1　(HER)　and　62.6　mV　dec-　1　(OER),　respectively.　Superior　cycling　ability　was　also　obtained　throughout　the　alkaline　HER　and　OER　processes,　showing　its　potential　for　use　in　real-world　scenarios　in　the　future.　The　simple　synthetic　strategy　for　producing　efficient　ST/CAO　based　HER　and　OER　electrocatalysts　for　electrochemical　water　splitting　presents　a　cost-effective　approach.　Additionally,　the　prepared　TPWCoR　nanocatalyst　achieves　around　96.87　%　ciprofloxacin　(CF)　photodegradation　after　60　min　of　UV　irradiation.　Analytical　definitions　of　the　best　catalyst　photodegradation　processes　may　be　made　as　variables　of　catalysts,　dosage,　and　pH　of　the　reaction　media.　All　of　these　discoveries　reveal　novel　understanding　of　how　to　construct　low　cost,　reusable　electro-photocatalysts　with　high　water　splitting　and　photodegradation　efficiency.
