Promoted CO2 Reforming with Bioethanol over TiO2-Supported Photothermal Catalysts
Reducing the greenhouse gas CO2 in the atmosphere and converting it into high-value-added syngas is regarded as a competitive strategy in line with green and sustainable development. Herein, a series of M/TiO2 (M = Cu, Co, Ni) catalysts were developed for photothermal CO2 reduction with bioethanol,...

| description | Reducing the greenhouse gas CO2 in the atmosphere and converting it into high-value-added syngas is regarded as a competitive strategy in line with green and sustainable development. Herein, a series of M/TiO2 (M = Cu, Co, Ni) catalysts were developed for photothermal CO2 reduction with bioethanol, and the synergistic mechanism between photocatalysis and thermocatalysis was deeply investigated. Systematic characteristics and photothermal ethanol dry reforming (EDR) testing results revealed the relevancy between catalytic behavior and microstructure properties of TiO2-supported catalysts. Notably, the Ni/TiO2 catalyst displayed superior catalytic behavior than Cu/TiO2 and Co/TiO2 counterparts, which mainly attributed to their abundant oxygen vacancies and stronger Ni–TiO2 interaction. In addition, both the narrower band gap and higher light absorption ability directly promoted the Ni/TiO2 catalyst possessing outstanding ethanol conversion (94.5%) and controllable H2/CO ratio (0.65) at 450 °C. Furthermore, the relatively less activation energy also determined that the Ni/TiO2 sample possessed the fastest kinetic progression in the EDR process. Therefore, the Ni/TiO2 catalyst exhibited the better photothermal catalytic activity compared with other 2 samples. We anticipate that photothermal synergy would offer good technical guidance to promote the conversion and utilization of greenhouse gas CO2 under relatively low temperature environment. |
