Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>SiC materials with tailored porosity and integrated Ni NPs (Ni@SiC) were synthesized <italic>via</italic> microphase separation of polycarbosilane‐<italic>block</italic>‐polyethylene followed by its pyrolysis. Changing the length of organic block allowed the synthesis of micro, meso and hierarchical Ni@SiC materials which were characterized by PXRD, TEM, TGA, and nitrogen physisorption. Selective hydrogenolysis of aryl ethers mimicking the most abundant linkages of lignin was achieved in water avoiding the possible hydrogenation of aromatic rings.</p> </abstract>
