Embodiment 1
[0032] Carrier preparation: In a 1 L beaker, 13 g La (NO 3 ) 3 ·6H 2 O was dissolved in 200 mL of water with stirring, and then 1.0 mol·L was added dropwise. -1 NH 4 HCO 3 The precipitant adjusts the pH of the mixed slurry to 8.0. After continuing to stir for 0.5 h, the reactant was filtered and washed until the pH of the filtrate was 7.0, dried in an oven at 120 °C overnight, and finally calcined in a muffle furnace at 600 °C for 2.0 h to obtain the catalyst carrier La 2 O 2 CO 3 ;
[0033] Catalyst preparation: 3.0 g of the above La was added to a 50 mL crucible under infrared light irradiation 2 O 2 CO 3 carrier, weigh 0.30g Ni (NO 3 ) 2 ·6H 2 O was dissolved in 7 mL of water to obtain a precursor solution. The precursor solution was added to the crucible and immersed while stirring. After the solvent was evaporated to dryness, it was dried in an oven at 120 °C overnight, and calcined in a muffle furnace at 750 °C for 2.0 h. in tube furnace H 2 / N 2 (volume...
Embodiment 2
[0035] Carrier preparation: In a 1 L beaker, at room temperature (around 25 °C), 24 g La (CH 3 COO) 3 ·5H 2 O was dissolved in 200 mL of water with stirring, and then 0.5 mol L was added dropwise. -1 NH 3 ·H 2 O precipitant adjusts the pH of the mixed slurry to 8.0. After stirring for 0.5 h, the reactant was filtered and washed until the pH of the filtrate was 7.0, dried in an oven at 120 °C overnight, and finally calcined in a muffle furnace at 600 °C for 3.0 h to obtain the catalyst carrier La 2 O 2 CO 3 ;
[0036] Catalyst preparation: 3.0 g of the above La was added to a 50 mL crucible under infrared light irradiation 2 O 2 CO 3 carrier, weigh 0.40g Ni (CH 3 COO) 2 ·4H 2 O was dissolved in 7 mL of water to obtain a precursor solution. The precursor solution was added to the crucible and immersed while stirring. After the solvent was evaporated to dryness, it was dried in an oven at 120 °C overnight, and calcined in a muffle furnace at 800 °C for 2.0 h. in tu...
Embodiment 3
[0038] Carrier preparation: In a 1 L beaker, add 10 g LaCl at room temperature (around 25 °C) 3 Stir to dissolve in 200 mL of water, and then dropwise add 2.0 mol L -1 (NH 4 ) 2 CO 3 The precipitant adjusts the pH of the mixed slurry to 9.0. After continuing to stir for 0.5 h, the reactant was filtered and washed until the pH of the filtrate was 7.0, dried in an oven at 120 °C overnight, and finally calcined in a muffle furnace at 600 °C for 4.0 h to obtain the catalyst carrier La 2 O 2 CO 3 ;
[0039] Catalyst preparation: 3.0 g of the above La was added to a 50 mL crucible under infrared light irradiation 2 O 2 CO 3 Carrier, weigh 0.43g NiCl 2 ·6H 2 O was dissolved in 7 mL of water to obtain a precursor solution. The precursor solution was added to the crucible and immersed while stirring. After the solvent was evaporated to dryness, it was dried in an oven at 120 °C overnight, and calcined in a muffle furnace at 600 °C for 2.0 h. in tube furnace H 2 / N 2 (vol...
