Sb₂Se₃ assembling Sb₂O₃@ attapulgite as an emerging composites for catalytic hydrogenation of p-nitrophenol.

ABSTRACT: The construction and application of a new type of composite material are achieved more and more attention. However, expected Sb₂Se₃/attapulgite composites aim to use the low price, and high adsorption of attapulgite in assembling Sb₂Se₃ is quite difficult to be acquired by a facile and benign environmental hydrothermal method. In this manuscript, we developed a new way for preparation of an emerging composite by means of Sb₂O₃ as a media linking Sb₂Se₃ and attapulgite together, and finally won an emerging composite Sb₂Se₃/Sb₂O₃@attapulgite, which presented an excellent catalytic properties for catalytic hydrogenation of p-nitrophenol. It was noted that the Sb₂Se₃/Sb₂O₃@attapulgite composites exhibited a high conversion rate for the hydrogenation of p-nitrophenol that was up to 90.7% within 15?min, which was far more than the 61.5% of Sb₂Se₃ sample. The excellent catalytic performance was attributed to the highly dispersion Sb₂Se₃ microbelts and Sb₂Se₃@Sb₂O₃@attapulgite rods, which would improve the adsorption of the reactant species and facility electronic transfer process of the catalytic hydrogenation of p-nitrophenol.
