Mechanism of Protection of Catalysts Supported in Redox Hydrogel Films

17-Apr-2015 | Vincent Fourmond; Stefanie Stapf; Huaiguang Li; Darren Buesen; James Birrell; Olaf Rüdiger; Wolfgang Lubitz; Wolfgan ..., Journal of the American Chemical Society, 2015

The use of synthetic inorganic complexes as supported catalysts is a key route in energy production and in industrial synthesis. However, their intrinsic oxygen sensitivity is sometimes an issue. Some of us have recently demonstrated that hydrogenases, the fragile but very efficient biological ...
