“… 7 The adsorption of CO over Rh/CeO 2 studied experimentally with infrared (IR) spectroscopy in the temperate range of 90 to 300 K, reports that at 90 K, the observed IR peak at 2163 cm −1 is more sensitive to CO pressure than that noticed at 2186 cm −1 8 The adsorption and dissociation of CO over Co–Si(111) surface was examined using X-ray photo-electron spectroscopy (XPS), showing that room temperature CO adsorption takes place only at Co-rich condition. 9 Zhang et al theoretically investigated the reactivity of the Cu 3 Pt(111), Pt(111) and Cu(111) surfaces towards CO and found that the molecule prefers to adsorb on an atop site of Pt. 10 It is found that multilayered porous graphene sheets strongly interact with CO, resulting in chemisorption with significant amount of charge exchange.…”

The drying procedure is an important consideration for the silicon powder processing. Herein, a comparative investigation of the drying efficiency, drying performance, and energy consumption of silicon powder after separation and purification of monocrystal silicon cutting slurry by using the hot air, far‐infrared and microwave drying treatments. The results show that microwave drying of 30 g silicon powder takes only 12 min, which is much shorter than hot air drying of 200 min and far infrared drying of 40 min. The water evaporation energy consumption of microwave drying reached 73.5 g/kW·h, which was 3.3 times than that of far infrared drying and 16.5 times than that of hot air drying. For 1 kg of silicon powder, the power consumption of microwave drying was 8 kW·h, while the far‐infrared drying was 26.7 kW·h, and the hot air drying was 133.4 kW·h, respectively. Therefore, effects of microwave power, drying temperature and drying time on the dehydration rate of silicon powder were investigated and optimized by response surface method, demonstrating that the microwave drying dehydration rate of 30 g silicon powder could reach 97.65%, and the power consumption could be reduced to 6.7 kW·h/kg under the conditions of microwave power of 1000 W, drying temperature of 89°C and drying time of 12 min. The present study shows that microwave drying of silicon powder is an energy‐saving and efficient process with good industrial application prospects.
