In this contribution, we report that low-loading Ru on a sol-gel anatase TiO2 (TiO2-A-SG) can upcycle polyolefin into small hydrocarbons under H2 through hydrocracking, in addition to hydrogenolysis that is common on Ru catalysts. Compared to hydrogenolysis, hydrocracking shows more desired product selectivity in minimal low-valued C1-3, liquids with narrower carbon distribution, more isomers, and can be achieved on Ni with efficiency close to on noble metals.
