Science Daily June 21, 2021 AgIO3 is useful for the CO2 reduction reaction. However, it needs much higher energy than what visible light can provide to function as an efficient photocatalyst. Researchers in Japan developed a new photocatalyst that incorporates single-walled carbon nanotubes (SWCNTs) with AgIO3 and AgI to form a three-component composite catalyst which solve both the synthesis and the electron transfer pathway problems. Spectroscopic observations using the composite showed that during the synthesis process, the encapsulated iodine molecules received charge from the SWCNT and converted into specific ions. They reacted with AgNO3 to form AgI and AgIO3 microcrystals, […]

Low-temp photocatalyst could slash the carbon footprint for syngas
Science Daily January 10, 2020 Traditional thermocatalytic processes to produce syngas require high temperatures and suffer from coke-induced instability. A team of researchers in the US (Rice University, Princeton University, UCLA, UC Santa Barbara) has developed a plasmonic photocatalyst consisting of a Cu nanoparticle ‘antenna’ with single-Ru atomic ‘reactor’ sites on the nanoparticle surface, ideal for low-temperature, light-driven methane dry reforming. This catalyst provides high light energy efficiency when illuminated at room temperature. In contrast to thermocatalysis, long-term stability (50 h) and high selectivity (>99%) were achieved in photocatalysis. This photocatalyst design could be relevant for future energy-efficient industrial processes…read more. […]
