摘要

Abstract

A series of nanorod-like porous Pd/γ-Al

catalysts with controllable textural properties and enhanced catalytic performance in 2-ethyl-9

10-anthraquinone (eAQ) hydrogenation for H

preparation were successfully prepared

via

a facile sol-gel method using aluminum isopropoxide as aluminum precursor and eAQ as structure directing agent

sequential calcination and impregnation process with Na

PdCl

solution. The physicochemical properties of the catalysts obtained with different addition amounts of eAQ were comparatively characterized by XRD

TG-DSC

BET

TEM

CO-TPR

-TPR and H

-O

titration. The results show that addition of eAQ can not only effectively control the textural properties (surface area

pore volume and average pore size) of the catalysts

but also lower their reduction temperature of active metal. Importantly

the catalyst obtained with an addition amount of 4 wt% eAQ shows the highest hydrogenation efficiency of 10.28 g·L

-1

which is 37.3% higher than 7.49 g·L

-1

of the catalyst obtained without eAQ.
