NOVELTY - Preparing tungsten trioxide/polypyrrole/graphene composite material involves preparing attapulgite/ tungsten trioxide by dispersing phosphotungstic acid into 20 milliliter ethanol, drying at room temperature calcining under air for 4 hours. The calcined samples are dispersed in 20 milliliter of ethanol dissolved in 1 gram of phosphotungstic acid, dried at room temperature, calcined in the air for 4 hours. USE - Method for preparing tungsten trioxide/polypyrrole/graphene composite material (claimed). DETAILED DESCRIPTION - Preparing tungsten trioxide/polypyrrole/graphene composite material involves preparing attapulgite/ tungsten trioxide by dispersing phosphotungstic acid into 20 milliliter ethanol, drying at room temperature calcining under air for 4 hours. The calcined samples are dispersed in 20 milliliter of ethanol dissolved in 1 gram of phosphotungstic acid, dried at room temperature, calcined in the air for 4 hours. The attapulgite/ tungsten trioxide/polypyrrole is prepared by dispersing 1 gram attapulgite/tungsten trioxide into 50 milliliter 20% ethanol solution, adding pyrrole monomer, 50 milliliter 20% ethanol followed by adding ferric chloride solution hexahydrate, stirring at room temperature, centrifuging product, washing, and freeze-drying. The attapulgite/tungsten trioxide/polypyrrole/graphene is prepared by dispersing 1 gram attapulgite/tungsten trioxide/polypyrrole into 50 milliliter 1 milligram l, adding 4.5 milliliter concentrated hydrochloric acid, adding zinc powder, ultrasound for 30 minutes followed by adding 5 milliliter concentrated hydrochloric acid to removing excess zinc powder, centrifuging product, washing, and freeze drying. The tungsten trioxide/ polypyrrole/graphene is prepared by dispersing attapulgite/tungsten trioxide/polypyrrole/graphene complex in 40% hydrofluoric acid, stirring for 48 hours. The product is centrifuged, washed, and lyophilized to obtain final product.
