1、從而在浸漬的過(guò)程中未能充分負(fù)載在載體表面,使得Ni粒子量不足,未能達(dá)到應(yīng)有的催化效果,活性下降。 2、主要是由于油相過(guò)多同時(shí)用于維系“水核”表面膜的CTAB過(guò)少,使得該微乳體系的穩(wěn)定性變差,Ni粒子易于析出、團(tuán)聚。當(dāng)V值逐漸增大直至5:5時(shí),由于油相偏少,體系中形成的“水核”較大,其中容納Nit粒子較多,碰撞程度加劇,從而增大了從體系中析出的Ni的體積,降低了Ni的催化效率。 3、V=1:7和2:8時(shí),催化劑的催化活性和V=3:5差別不大,但在最佳活性點(diǎn)選擇性相對(duì)較低,因此選擇V=3:5為CTAB與正丁醇的最佳配比。 |

1、從而在浸漬的過(guò)程中未能充分負(fù)載在載體表面,使得Ni粒子量不足,未能達(dá)到應(yīng)有的催化效果,活性下降。 Therefore during the extraction process, it failed to sufficiently coat the surface of the carrier, led to inadequate amount of N-particles (incorporated) to provide the catalytic activity that we had wished for 2、主要是由于油相過(guò)多同時(shí)用于維系“水核”表面膜的CTAB過(guò)少,使得該微乳體系的穩(wěn)定性變差,Ni粒子易于析出、團(tuán)聚。當(dāng)V值逐漸增大直至5:5時(shí),由于油相偏少,體系中形成的“水核”較大,其中容納Nit粒子較多,碰撞程度加劇,從而增大了從體系中析出的Ni的體積,降低了Ni的催化效率。 This is mainly because there was too much oil phase in the system and too few CTAB to sustain the water core structure, which compromised the stability of the microemulsion and N-particles tend to aggregate and become phase separated. When the V value was gradually increased to 5:5, the system started to form large water cores due to reduced oil phase, more N-particles were entrapped, which led to more fractions of N-particles leaked out as a result of increased collision amount the particles themselves, reduced the catalytic activity of the N-particles. 3、V=1:7和2:8時(shí),催化劑的催化活性和V=3:5差別不大,但在最佳活性點(diǎn)選擇性相對(duì)較低,因此選擇V=3:5為CTAB與正丁醇的最佳配比。 3. When V=1:7 to 1:4 (應(yīng)該用最小公約數(shù),而不是2:8), the catalytic activity of the product( or catalyst) was not much different from that of V=3:5, however, the selectivity at the point the most catalytic activity was achieved was relatively poor, therefore the V=3:5 of CTAB:n-butanol was selected as the optimal ratio. |
