Understanding the role of heat transfer between catalysts and substrates is important for enhancing photothermal CO2 catalysis. Herein, we investigate the effect of different substrates, including silicon wafers, glass slides and copper plates, on the photothermal catalytic performance of commercial Ni catalysts. The highest CO2 conversion rate and CO selectivity are observed in the catalyst film on the glass substrate, and this can be traced to a reduced catalyst-to-substrate heat transfer that increases the catalyst temperature under illumination. Our study reveals the important role of thermal management between catalysts and substrates in photothermal catalysis and sheds light on reactor design for efficient solar-to-chemical energy conversions.

通过绝热基材增强光热 CO2 催化

了解催化剂和底物之间传热的作用对于增强光热 CO2 催化非常重要。在此，我们研究了不同基材（包括硅片、载玻片和铜板）对商业镍催化剂光热催化性能的影响。在玻璃基板上的催化剂膜中观察到最高的 CO2 转化率和 CO 选择性，这可以追溯到减少的催化剂到基板的热传递，从而增加了光照下的催化剂温度。我们的研究揭示了催化剂和底物之间的热管理在光热催化中的重要作用，并阐明了用于高效太阳能到化学能量转换的反应器设计。
