Selective hydrogenation of lignin-derived compounds under mild conditions

Paul Joseph Dyson, Gabor Laurenczy, Antoine Philippe Van Muyden, Lu Chen, Xinjiang Cui

A key challenge in the production of lignin-derived chemicals is to reduce the energy intensive processes used in their production. Here, we show that well-defined Rh nanoparticles dispersed in sub-micrometer size carbon hollow spheres, are able to hydroge ...
