Hydrothermally reduced graphene oxide as a sensing material for electrically transduced pH sensors

•The electrochemical nature of oxygen functional groups present on the hydrothermally reduced graphene oxide is investigated by cyclic voltammetry techniques.•Hydrothermally reduced graphene oxide based potentiometric and chemiresistive pH sensor is fabricated as a reagent less sensing probe.•Chemir...
