The 0.5 wt.% Pd/C catalysts used for purification of terephthalic acid(TA) were prepared, and the effects of dodecyltrimethylammonium bromide(DTAB) concentration on activity and microstructure of catalysts were investigated by means of SEM, TEM, XRD,HPLC,specific surface area(BET) and porosity test. The results show that DTAB can increase the activity of Pd/C catalysts, and the catalytic activity increases with the increase in DTAB concentration and nearly remains constant with further increase after it exceeds 0.5 wt.%.. DTAB can clean the surface of activated carbon and diminish the palladium size of Pd/C catalysts. The addition of DTAB has effects in crystal structure of nano Pd/C catalysts, and the Pd crystal planes of (111) and (200) was replaced by a broad reflections after DTAB added. DTAB tends to form various meta-stable structures(spherical or cylindrical)at the solid-liquid interface that helps finer grain for mation and hinders subsequent coarsening of the palladium particles.

Abstract Development of robust alkaline oxygen evolution reaction electrocatalysts is crucial for the efficiency of water splitting. Herein, Fe-MOF nanocones array on nickel foam are synthesized by introducing sodium hypochlorite, leading to Cl substitution of terephthalic acid in Fe-MOFs (Fe-MOF-Cl/NF). Experimental results show that Fe-MOF-Cl/NF exhibits enhanced OER activity over Fe-MOF/NF, lowering η50 from 292.4 to 222.7 mV. In combination with density function theory calculations, the improved OER performance is attributed to engineering electronic structure of Fe sites which accelerate the third step from *O to *OOH, and promote OER kinetics. Additionally, Fe-MOF-Cl/NF can retain catalytic activity for 100 h.
