Summary: Thermochemical methane reforming driven by solar energy is an efficient method for energy storage and greenhouse gas reduction. By comparing steam reforming of methane driven by pure thermal heating and direct light irradiation, it is found that the light-driven system shows improved conversion and reaction rate. The presence of light on the nickel oxide surface activates CH4 desorption and facilitates CHxO species evolution. By optimizing chemical looping reactions and operation conditions, a solar-to-fuel efficiency of 16% is achieved.

Summary: Thermochemical methane reforming driven by solar energy is an efficient way to store renewable energy and reduce greenhouse gas emission. In this study, we compared the reaction reactivity of steam reforming of methane driven by pure thermal heating and direct light irradiation. We found that the light-driven system showed improved conversion and reaction rate. Through experiments, we postulated that light on the nickel oxide surface activated CH4 desorption and facilitated CHxO species evolution. By selecting appropriate chemical reactions and operation conditions, a solar-to-fuel efficiency of 16% was achieved. These results demonstrate the potential of designing more energy-efficient chemical processes with direct sunlight irradiation for solar fuel production.

Summary: Oxy-steam combustion is a promising technology for reducing CO2 emissions. This study investigated the transformation and release of nitrogen under oxy-steam conditions, revealing that char prepared in a N-2/H2O atmosphere has higher nitrogen content compared to a N-2 atmosphere. The presence of OH radicals inhibits the transformation of N-Q to N-6 and promotes the conversion of N-6 to N-5, ultimately leading to lower emissions of HCN and NH3 under N-2/H2O conditions.

Summary: This study investigated the effect of W and Mo modification on arsenic adsorption over Cu/gamma-Al2O3 catalyst. Results showed that W and Mo modification improved the NO conversion activities at low temperatures and reduced the arsenic adsorption on Cu/gamma-Al2O3 catalyst. W modification had a stronger promotion effect on arsenic resistance compared to Mo modification, and the proportion of As5+ on the W-Cu/gamma-Al2O3 surface was larger than that on the Mo-Cu/gamma-Al2O3 surface. Theoretical simulations revealed that Al2O3 adsorption on Mo-Cu/gamma-Al2O3 surface was stronger than that on W-Cu/gamma-Al2O3 surface.
