Cellulose nanocrystals (CNC) derived Mo2C@sulfur-doped carbon aerogels for hydrogen evolution

S-doped ultrafine molybdenum carbide anchored on cellulose nanocrystals (CNC) derived carbon composite aerogels (Mo2C@S-CA) were synthesized for HER by a simple one-step carbonization method, utilizing inorganic-organic hybrid ammonium molybdate/CNC (AMM/CNC) as precursor. The as-synthesized catalysts exhibit superior HER activity.204
