Hydroxide Ligands Cooperate with Catalytic Centers in Metal–Organic Frameworks for Efficient Photocatalytic CO2 Reduction

Abstract: Converting CO into fuels via photochemical reactions relies on highly efficient and selective catalysts. We demonstrate that the catalytic active metal center can cooperate with neighboring hydroxide ligands to boost the photocatalytic CO reduction. Six cobalt-based metal-organic frameworks (MOFs) with different coordination environments are studied at the same reaction condition (photosensitizer, electron donor, water/organic mixed solvent, and visible light). In pure CO at 1.0 atm, the MOFs bearing μ-OH liga… Show more

“…The efficient CO 2 photoreduction systems are typically composed of several modules, such as light harvesters, electron mediator, CO 2 activators and their desired integration, to operate the reaction through a tandem manner. [24][25][26][27] Nickel and cobalt species with rich redox states have been demonstrated to be active sites of photocatalysts, which can powerfully promote the separation and transfer of light-excited charges of CO 2 photoconversion catalysis. [18,[26][27][28][29][30][31] When the reduction reaction is further coupled with the protons, reinforced performance of CO 2 photoreduction can be achieved.…”
