Reverse water-gas shift: This study reports a Au/TiO₂ catalyst which promotes the rWGS reaction under mildly concentrated solar irradiation at ambient temperature. A quantum efficiency of 4.7 % was reached, with a selectivity to CO of 98 %. This activity is achieved due to a plasmonic photothermal effect from the Au nanoparticles, while the high selectivity is likely caused by charge transfer processes which promote the desorption of products from the catalyst surface.

使用等离子体 Au/TiO2 纳米催化剂在低温阳光下将 CO2 还原为 CO

反向水煤气变换：该研究报告了一种 Au/TiO ₂催化剂，它在环境温度和温和集中的太阳辐射下促进了 rWGS 反应。达到了 4.7% 的量子效率，对 CO 的选择性为 98%。这种活性是由于 Au 纳米粒子的等离子体光热效应而实现的，而高选择性可能是由促进产物从催化剂表面解吸的电荷转移过程引起的。
