As　a　kind　of　lignocellulosic　biomass,　Pennisetum　sinense　(P.　sinense)　is　commonly　used　as　animal　feed,　fertilizer　or　papermaking　raw　materials.　Based　on　the　high　carbon　content　and　renewability　of　P.　sinense,　we　explored　the　possibility　and　feasibility　of　using　it　as　catalyst　matrix.　The　catalyst　was　produced　by　sulfonation　of　char　obtained　from　the　carbonization　of　P.　sinense　at　550　degrees　C.　The　structure　of　the　catalyst　was　characterized　by　SEM,　BET,　XRD,　FT-IR,　XPS　and　TGA,　and　its　catalytic　performance　for　the　hydrolysis　of　cellulose　was　investigated　in　detail.　The　highest　acidity　of　the　catalyst　was　3.79　mmol/g　and　the　maximum　glucose　yield　of　59.92%　was　achieved　under　optimized　conditions.　The　catalyst　also　showed　a　promising　reusability.　The　glucose　yield　was　53.01%　after　5　cycles　and　as　high　as　55.92%　when　using　the　regenerated　catalyst.　(C)　2020　Elsevier　B.V.　All　rights　reserved.
