For instance, complete suppression of the competing H2 evolution during photocatalytic CO2-to-CO conversion has not been achieved before. We design and synthesize a spongy nickel-organic heterogeneous photocatalyst via a photochemical route. The catalyst has a crystalline network architecture with a high concentration of defects. It is highly active in converting CO2 to CO, with a production rate of ~1.6 \u00d7 104 \u03bcmol hour\u22121 g\u22121. No measurable H2 is generated during the reaction, leading to nearly 100% selective CO production over H2 evolution. When the spongy Ni-organic catalyst is enriched with Rh or Ag nanocrystals, the controlled photocatalytic CO2 reduction reactions generate formic acid and acetic acid. Achieving such a spongy nickel-organic photocatalyst is a critical step toward practical production of high-value multicarbon fuels using solar energy.<\/p><\/blockquote>\n<p>Source: <em><a href=\"http:\/\/advances.sciencemag.org\/content\/3\/7\/e1700921\">A spongy nickel-organic CO2 reduction photocatalyst for nearly 100% selective CO production | Science Advances<\/a><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Solar-driven photocatalytic conversion of CO2 into fuels has attracted a lot of interest; however, developing active catalysts that can selectively convert CO2 to fuels with desirable reaction products remains a grand challenge.
