  • Tungsten Carbide: A Remarkably Efficient Catalyst for the

    Breaking up: Tungsten carbide shows remarkable activity in selective C−O bond cleavage of typical βO4 model compounds and deconstruction of lignin feedstocks High yields of C−O cleavage products from model compounds (up to 968 %) and from lignin feedstock (up to 707 %) are obtained without destroying the aromatic ringsTungsten carbide exhibits platinumlike behavior, which makes it an interesting potential substitute for noble metals in catalytic applications Tungsten carbide nanocrystals (≈5 nm) are directly synthesized through the reaction of tungsten precursors with mesoporous graphitic C 3 N 4 (mpgC 3 N 4 ) as the reactive template in a flow of inertTungsten Carbide Nanoparticles as Efficient CocatalystsAn ecofriendly and robust strategy is developed to construct a selfsupported monolithic electrode composed of Ndoped carbon hybridized withHybridization of Bimetallic
