Flame spray-synthesized Pt/TiO2 and PtCo/TiO2 catalysts with 0.7 wt% Pt and 0–0.4 wt% Co were studied in the hydrogenation of furfural to furfuryl alcohol (FA) at 50 °C and 2 MPa H2. Particle formation under high temperature flame facilitated high Pt dispersion and formation of Pt-TiOx interface sites, which were beneficial for furfural conversion to FA. Modifying with Co accelerated rutile phase TiO2 formation, which strongly diminished hydrogenation activity on the (FSP)-PtCo/TiO2. On the other hand, (I)-PtCo/TiO2 prepared by conventional impregnation, anatase phase TiO2 was preserved (> 85%) and both furfural conversion and FA selectivity increased upon increasing Co loading.

火焰喷雾合成的Pt-Co / TiO 2催化剂,用于糠醛选择性加氢为糠醇

研究了在50°C和2 MPa H 2的糠醛加氢制糠醇(FA)中,火焰喷涂合成的Pt / TiO 2和PtCo / TiO 2催化剂,其中Pt / TiO 2含量为0.7wt%和PtCo / TiO 2催化剂。高温火焰下的颗粒形成促进了高Pt分散和Pt-TiO x界面位点的形成,这有利于糠醛转化为FA。用Co改性可加速金红石相TiO 2的形成,从而大大降低了(FSP)-PtCo / TiO 2的加氢活性。另一方面,通过常规浸渍制备的(I)-PtCo / TiO 2,锐钛矿相TiO 2 保留(> 85%),糠醛转化率和FA选择性都随着Co负载的增加而增加。
