在这项工作中，我们介绍了HI光，表面工程玻璃波导为基础的“壳管式”光热反应器，这是既可扩展的直径和长度。我们研究了温度，光照，和停留时间的影响，其光热催化性能CO2加氢形成CO，与立方相缺陷负载氧化铟，In 2 O3-x（OH）y，催化剂。我们证明了在各种反应条件下的光增强效应。值得注意的是，立方晶系光催化剂的点亮性能在300°C和大气压下表现出15.40 mmol gcat-1 hr-1的CO释放速率。这比先前报道的立方晶型的In 2 O3-x（OH）y催化剂在相当的操作条件下每单位时间每单位催化剂质量的转化率高20倍，并且比其菱形多晶型高5倍以上。该结果强调了光热催化反应器设计的改进能够实现均匀的光分布和更好的反应物/催化剂混合，从而显著提高催化剂利用率。- 开发了一种基于玻璃波导管的“壳管式”光热反应器。该反应器对CO2还原具有很高的光热催化性能。该模块化反应器在直径和长度方面都具有放大潜力。反应器设计改善了光分布和反应物/催化剂混合。催化;能源可持续性;能源资源;能源储存
In this work, we introduce HI-Light, a surface-engineered glass-waveguide-based “shell-and-tube” type photothermal reactor which is both scalable in diameter and length. We examine the effect of temperature, light irradiation, and residence time on its photo-thermocatalytic performance for CO2 hydrogenation to form CO, with a cubic phase defect-laden indium oxide, In2O3-x(OH)y, catalyst. We demonstrate the light enhancement effect under a variety of reaction conditions. Notably, the light-on performance for the cubic nanocrystal photocatalyst exhibits a CO evolution rate at 15.40 mmol gcat−1 hr−1 at 300°C and atmospheric pressure. This is 20 times higher conversion rate per unit catalyst mass per unit time beyond previously reported In2O3-x(OH)y catalyst in the cubic form under comparable operation conditions and more than 5 times higher than that of its rhombohedral polymorph. This result underscores that improvement in photo-thermocatalytic reactor design enables uniform light distribution and better reactant/catalyst mixing, thus significantly improving catalyst utilization. - A glass-waveguide-based “shell-and-tube” type photothermal reactor was developed The reactor exhibited a high photothermal catalytic performance for CO2 reduction - The modular reactor has potential for scale-up, both in diameter and length The reactor design improves light distribution and reactant/catalyst mixing Catalysis; Energy Sustainability; Energy Resources; Energy Storage
