Abstract A pioneering robust and green heterogeneous acidic catalyst (CSA@g-C3N4) was rationally designed via immobilization of camphorsulfonic acid (CSA) on the g-C3N4 surface under mild conditions. Grafting CSA in the g-C3N4 lattice is distinguished as the root cause of facilitating the structure change of g-C3N4. leading to a unique morphology. accordingly the remarkable catalytic ... https://lightspeedlovers.shop/product-category/chastity-cages/
