[0020] (1) Preparation of Pd supported photocatalyst:
[0021] Take TiO 2 The material is dispersed in deionized water, ultrasonically stirred, and TiO is added by pressing 2 Add 0.5%-1.5% of the mass to sodium chloropalladate solution, adjust the pH to 7-10 with NaOH solution, add glucose, water bath for 0.5-2h at a temperature of 60-90°C, centrifuge, wash, and vacuum dry to obtain Pd / TiO 2 catalyst of light;
[0022] (2) Photocatalytic CO 2 Hydrogenation reaction:
[0023] Tin foil paper is added to the inner wall of the high-pressure visible micro-kettle reactor, which plays a role in concentrating light. The quartz wool evenly disperses and supports the catalyst, and a certain space is left at the bottom for stirring to strengthen the gas flow. The photocatalyst is dispersed on the quartz wool. 2 Remove the internal air for half an hour, add 2-3MPa H 2 with 0.5-1MPa CO 2 , 100-150W mercury lamp is used as light source, photocatalytic hydrogenation reaction is carri...
