[0049] Example 2: Cu / TiO 2 -CeO 2 Thermocatalytic Performance Test of Composite Porous Oxide Catalysts
[0050] Such as figure 1 As shown, take 8 mg of catalyst loaded on the glass fiber membrane, and place it in a special reaction tube. During the reaction process, methanol / water vapor is continuously delivered in front of the reaction tube, the reactor is set to the required temperature, and the light-transmitting hole is covered. At this time, the composite catalyst only performs methanol reforming hydrogen production under purely thermal conditions at the desired temperature. The reaction conditions are methanol:water=1:1.2, the sampling speed is 4uL / min, and the gas at the outlet of the reactor is sent to a gas chromatograph for detection. Such as Figure 5 As shown, the hydrogen production rate is 22.0mmol / h / g at 275°C and 58.6mmol / h / g at 300°C. Demonstration of Cu / TiO under thermal conditions 2 -CeO 2 The composite oxide catalyst has thermocatalytic properties. ...

[0051] Example 3: Cu / TiO 2 -CeO 2 Photothermal Coupling Catalytic Performance Test of Composite Porous Oxide Catalysts
[0052] Take 8 mg of catalyst loaded on the glass fiber membrane, and place it in a special reaction tube. During the reaction process, the methanol / water vapor is continuously transported in front of the reaction tube, the reactor is set to the required temperature, and the xenon lamp is turned on to irradiate sunlight. The special-shaped holes on the wall are introduced into the surface of the catalyst. At this time, the composite catalyst absorbs high-energy photons at the required temperature to perform photothermal coupling reforming to produce hydrogen. The reaction conditions are methanol: water = 1:1.2, the sampling speed is 4uL / min, and the gas at the outlet of the reactor is sent to a gas chromatograph for detection. The hydrogen production rate was 48.1 mmol / h / g at 275°C and 78.8 mmol / h / g at 300°C. Compared with the thermocatalytic hydrogen pr...
