Studies on the activity of phosphotungstic acid (HPW) supported on porous kaolin and effects on the catalytic activity

Kaolin is an abundant clay mineral and chemically natural hydrous aluminosilicate with the 1:1 type layered structure. In this work mesoporous material derived from raw kaolin was obtained using starch as organic template. The surface area of the kaolin derived porous clay heterostructure (PCH) has...
