A novel coordination polymer-based photocatalyst for CO2<\/sub> reduction exhibits unprecedented performance, giving scientists at Tokyo Tech hope in the fight against global warming. Made from abundant elements and requiring no complex post-synthesis treatment or modifications, this promising photocatalyst could pave the way for a new class of photocatalysts for efficiently converting CO2<\/sub> into useful chemicals.<\/strong><\/p>\n\n\n\n

The carbon dioxide (CO2<\/sub>) released into the atmosphere during fossil fuel burning is a leading cause of global warming. One way to address this growing threat is to develop CO2<\/sub> reduction technologies, which convert CO2<\/sub> into useful chemicals, such as CO and formic acid (HCOOH). In particular, photocatalytic CO2<\/sub> reduction systems use visible or ultraviolet light to drive CO2<\/sub> reduction, much like how plants use sunlight to conduct photosynthesis. Over the past few years, scientists have reported many sophisticated photocatalysts based on metal-organic frameworks and coordination polymers (CPs). Unfortunately, most of them either require complex post-synthesis treatment and modifications or are made from precious metals. <\/p>\n\n\n\n

In a recent study published in ACS Catalysis<\/em>, a research team Japan found a way to overcome these challenges. Led by Specially Appointed Assistant Professor Yoshinobu Kamakura and Professor Kazuhiko Maeda from Tokyo Institute of Technology (Tokyo Tech), the team developed a new kind of photocatalyst for CO2<\/sub> reduction based on a CP containing lead\u2013sulfur (Pb\u2013S) bonds. Known as KGF-9, the novel CP consists of an infinite (\u2013Pb\u2013S\u2013) n<\/sub> structure with properties unlike any other known photocatalyst. <\/p>\n\n\n\n

For instance, KGF-9 has no pores or voids, meaning that it has a low surface area. Despite this, however, it achieved a spectacular photoreduction performance. Under visible-light irradiation at 400 nm, KGF-9 demonstrated an apparent quantum yield (product yield per photon absorbed) of 2.6% and a selectivity of over 99% in the reduction of CO2<\/sub> to formate (HCOO\u2212<\/sup>). “These values are the highest yet reported for a precious metal-free, single-component photocatalyst-driven reduction of CO2<\/sub> to HCOO\u2212<\/sup>,” highlights Prof. Maeda. “Our work could shed light on the potential of nonporous CPs as building units for photocatalytic CO2<\/sub> conversion systems.”<\/p>\n\n\n\n

In addition to its remarkable performance, KGF-9 is easier to synthesize and use compared to other photocatalysts. Since the active Pb sites (where CO2<\/sub> reduction occurs) are already “installed” on its surface, KGF-9 does not require the presence of a cocatalyst, such as metal nanoparticles or metal complexes. Moreover, it requires no other post-synthesis modifications to operate at room temperature and under visible light illumination.<\/p>\n\n\n\n

The team at Tokyo Tech is already exploring new strategies to increase the surface area of KGF-9 and boost its performance further. As the first photocatalyst with Pb(II) as an active center, there is a good chance that KGF-9 will pave the way to a more economically feasible CO2<\/sub> reduction. In this regard, the research team concludes: “We believe that our study provides an unprecedented opportunity for developing a new class of inexpensive photocatalysts for CO2<\/sub>reduction consisting of earth-abundant elements.”<\/p>\n\n\n\n

Let us hope further research in this field will give us an edge in the fight against climate change.<\/p>\n\n\n\n
